Amarinth wins US$200,000 API 610 OH1 pump order in Iraq

0

The pumps are for condensate transfer duties and include the latest API 682 4th edition Plan 53B seal support systems along with Amarinth mobile top-up units.

The Iraqi Ministry of Oil-operated Majnoon oil field is a super-giant oil field located 60km from Basra in southern Iraq and is one of the richest oil fields in the world. The field is 52km-long, 15km-wide, includes 13 different oil and gas reservoirs, and has an estimated 38 billion barrels of oil in place.

Specified for ATEX Zone 1 use, the pumps are required on an aggressive 30-week delivery. On completion, they will be inspected and witness tested by Bureau Veritas, and supplied with a full legalised Iraq documentation package.

This is Amarinth’s first order from Azku Global Services and comes off the back of numerous projects that the UK pump company has successfully delivered into Iraq.

“We are delighted to receive this first order Azku Global Services which further strengthens our reputation in Iraq for successfully delivering robust and reliable pumping solutions on short lead times for its expanding oil and gas infrastructure,” said Oliver Brigginshaw, managing director of Amarinth. “Our ability to meet these aggressive delivery deadlines is assisted by the in-depth knowledge we developed across our organisation of the documentation and legislative processes required to supply pumps to Iraq.”

KSB Canada completes Lake Huron high lift pump replacement project

0

For half a century residents and commerce across eight municipalities of the greater London Area of south western Ontario have received their potable water supply from Lake Huron Water Treatment Plant (WTP) near Grand Bend and over this period the community has been well served. However, in 2017 the Lake Huron Primary Water Supply System (LHPWSS) announced an Energy Audit and Pump Optimization study that identified a significant opportunity for energy savings and the optimization of pump operations for the pumping station.

The outcome of this study has been the modification of the original five pump configuration in the pump station and its replacement with a six pump configuration. This has involved removing three of the original 50-year old 3000hp (2237kW) pumps and replacing them with four high lift pumps from KSB. With the new pumps running on their operational curve, substantial energy savings can be made. As an electrical transmission-connected entity, the LHPWSS was eligible under the Independent Electricity Systems Operator’s (IESO) Industrial Accelerator Program (IEP) for financial incentives for eligible energy efficiency projects.

Four international pump manufacturers submitted bids, but KSB Canada’s submission stood out. Despite being the highest capital expenditure cost by a significant amount, KSB’s submission actually offered the lowest overall anticipated lifecycle cost over 25 years.  This was possible due to KSB’s impressive energy efficiency and creative solution in offering a single type for all four pumps (large and small.) This reduced the spares requirement, in turn reducing the lifecycle cost and providing flexibility to easily increase pump capacity in the future as demand continues to increase. The contract was awarded to KSB Canada, who commenced design and consultation work in 2019. Pump manufacturing began in 2020 and the updated pumping station became fully operational in August 2022.

Lake Huron Primary Water Supply System

Located in Southwestern Ontario, along the Quebec City-Winsor Corridor, London is an interesting city as it gets its water source from both Lake Huron and Lake Erie. The Regional Water Supply Division of the City of London (RWS) is seconded to the regional Water Boards and responsible for two major water supply systems, these being the LHPWSS and the Elgin Area Primary Water Supply System (EAPWSS). The LHPWSS services the municipalities of London, Lambton Shores, North Middlesex, South Huron, Bluewater, Middlesex Centre, Lucan-Biddulph and Strathroy-Caradoc from a water treatment plant located north of the village of Grand Bend in South Huron.  The plant has a current treatment capacity of 340 million liters per day (75 million imperial gallons per day) and serves the city’s population of approximately 420,000 people in the eight municipalities, including 80% of the City of London.

The plant has a current treatment capacity of 340 million liters per day (75 million imperial gallons per day) and serves a population of approximately 420,000 people. 

The pumping station was originally designed for a single pipeline, but later in 1996 and 2014 the RWS partially twinned the 47km main transmission pipeline to a terminal reservoir resulting in the pumps no longer running on their curve.  “After almost 50 years, the existing pumps were becoming inefficient, with the impellers showing signs of pitting. Keeping them operational required a lot of ongoing maintenance because they were running off curve,” reports Billy Haklander, Capital Program Manager, LH&EAPWSS.

Pump selection

To give the LHPWSS the most flexibility in selecting pumps, four pump suppliers were invited to submit separate bids for the small and large pumps and to identify a credit should the LH&EAPWSS decide to source both the small and large pumps from the same supplier. KSB’s bid offered a creative solution using just a single type for all four pumps, with only the impellers and motors being different in accordance with the size of the pump. The base plates for each pump were the same size. The flexibility offered by KSB enabled the capital cost of its bid to be adjusted to account for fewer spares and thereby create savings for the customer.

A significant benefit of the proposal made by KSB was that with the smaller pumps using the same size casings and base plates as the two larger pumps, they had engineered the opportunity to increase the pump size by fitting larger impellers and motors at a future date.  This can be done on site without any civil works needing to be carried out. Thus, if demand grows for the water supply to be increased it can be accommodated with the minimum of cost and disruption to the plant.

Following a 25 year Life Cycle Cost analysis, taking into account the capital cost, energy consumption and maintenance costs made by AECOM Canada, consultants for LH&EAPWSS, the contract was awarded to KSB. Given that the pumps proposed by KSB met the technical requirements and offered the lowest overall anticipated lifecycle cost over 25 years, AECOM and RWS recommended that the proposal from KSB be accepted.

Installation challenges

“One of the constraints that we had to take into consideration when evaluating the bidders’ project was ability to conform to the available space in the existing pump hall,” explains Marcus Henderson, KSB National Operations Manager. “With this being an existing installation there was only so much real estate to work with and a key constraint was that the existing pumps were of a bottom suction configuration. Usually, the installation configuration for horizontal split case pumps is in-line with the suction and discharge in the same direction. This meant that we had to find a solution to incorporate bottom suction. We had to undertake some pattern work to incorporate the existing pipework which enabled us to solve the problem.”

“The eventual scope of the project involved the supply of four bottom suction horizontal split case pumps, vibration monitoring system and flow straighteners (suction conditioning spools) for potable water distribution (water supply)”, reports Marcus Henderson. “Also, part of the contract was to supply two TECO make 1494kW/2000hp @ 1200rpm, 4160V / 3Ph/60Hz and two TECO make 2611Kw/3500hp @ 1200rpm, 4160V / 3Ph/60Hz electric motors. We were also responsible for torsional and lateral analysis for the pump sets, on site start-up  and commissioning field services.”

The plant’s pumps are rated for 1,158 L/s, and each of the pumps’ discharge piping is equipped with a 500mm diameter tilting disk check valve, along with a 500mm diameter metal seated ball valve equipped with a motorized electric actuator. The WTP has two hydro pneumatic tanks, each with a capacity of 580m³, for transient protection of the 47km partially twinned 1200mm diameter water main distribution system.

The pumps specified were:

2 x RDLO 500-835 B SC G O BS

Design Flow Capacity: 900 L/s (78 ML/D)

Design Flow Pump Head: 125m TDH

Low RPM

Pump Starting: Soft Starter

 

2 x RDLO 500-835 A SC G O BS

Design Flow Capacity: 1,300 L/s (112 ML/D)

Design Flow Pump Head: 150m TDH

Low RPM

Pump Starting: Soft Starter

 

The RDLO pumps are rated for 1,300 L/s or 900 L/sec and each of the pumps’ discharge piping is equipped with a 600mm diameter tilting disk check & throttling valve and isolation ball valve each with a motorized actuator. 

RDLO pumps

Proven in many water applications around the world, the RDLO pumps were identified as being more than capable of meeting the customer’s specific demands. KSB’s RDLO axially split, single stage volute pumps have been developed specifically for handling raw water, clean water, service water and transport fluids with a minimum of flow resistance. As a result, they lower the energy and life cycle costs of the systems in which they are installed. They also meet the twin demands of reliability and high availability. Reliability results from the casing halves being sealed by solid casing split flanges at the upper and lower casing part, and high availability is attributable to the use of generously dimensioned bearings and high-quality shaft seals. Smooth running is ensured at all times thanks to the flow-optimised, vortex-free intake elbow and rigid shaft with short bearing span. Because the shaft is completely sealed without steps/threads in the wetted area the RDLO offers reliable power transmission.

The combination of solid bearing brackets, a short and rigid shaft and pre-loaded bearings guarantees low vibration and extended operating life for the bearings, seals and coupling. Being axially split case pumps simplifies maintenance procedures, enabling ready access to all parts for thorough inspection. The drive may be positioned on both the left and right of the pump without additional parts or modifications to the casing being necessary. ”Two of the pumps are connected up to 3500 hp motors and the other two to 2500 hp motors. These are the main pumps supplying drinking water to the entire LHPWSS with many customers over 50km away, so they consume a great amount of energy. It is marginal improvements such as these that can improve efficiency by one or two percent, but they work out to big dollars when you consider the overall size of the plant,” comments Henderson.

Installation

“Because the pumps were being retrofitted into the original premises, it was necessary to run the plant at half capacity on one transmission side during installation,” explains Haklander. “As there was a spare bay already in the plant it was possible to utilize this for the installation of the first pump. The procedure involved running pumps 1, 2 and 3 while pumps 5 and 6 were being installed. Once these pumps were tested and we were comfortable with their performance the procedure switched to running pumps 4, 5 and 6 while pumps 1, 2, and 3 were being installed.”

The introduction of the new pumps provided the opportunity to retrofit isolation valves. Historically the lack of the isolation valves on the existing pumps required the complete isolation of half of the discharge header board (three pumps) in order to facilitate the repair to one pump, effectively limiting the pump capacity of the plant to half of its rated capacity. The selection of a combined control/check valve to replace two valves on each pump discharge meant that each pump would have a dedicated isolation valve for each pump discharge. Isolation valves on each pump discharge will enable the complete isolation of the combination valve and the high lift pump for maintenance and repair purposes.

Pump efficiency

A significant element of the project was the issue of the pumps delivering energy savings, which involved factory acceptance testing at KSB’s Halle facility in Germany. Henderson explains: “Factory testing involved shipping one motor of each size to our factory and coupling them up to the pumps for string testing and recording the overall pump performance. The motors also underwent type testing under full load in accordance with the IEEE Standard so that they could determine motor efficiency.” He continues: “We took the factory overall power and the data from the motor factory to determine pump efficiency. There were strict penalties on performance guarantees on this project, so if we failed to meet the efficiency guarantees given, KSB would be required to pay LHPWSS the difference in energy costs delivered and  those which were guaranteed over the performance lifetime.”

“It is worth noting that when the pump tests were carried out, they had to be on bare internals. The coatings were only applied after testing, so it was a true test of the raw efficiency of the pumps. Given that coating can improve efficiency by one to two percent we faced some tough conditions.”

Conclusion

“The replacement of fifty-year-old high lift pumps at the Lake Huron Water Treatment Plant will result in significant energy savings and optimization of pump operations. The complexities of this large infrastructure project include the installation of two 2,000hp/1494kW and two 3,500hp/2611kW pumps and associated combination control and isolation valves as well as a medium voltage motor control centre, all while maintaining supply to the utility’s regional customers,” says Haklander.

“Working with KSB and the other vendors throughout a global pandemic provided unforeseen challenges, but I was amazed at how well the project went. The people at KSB in Canada were able to set up and accommodate the virtual site acceptance testing program and their engineers at the Halle plant in Germany were great in providing information when it was requested. KSB was at the front in making it a successful project and their collaboration with the key players, in particular Kenaidan Contracting the general contractor responsible for installing the pumps and the mechanical aspects of the project and overseeing the installation of the electrical components by their electrical sub-contractor Selectra, was greatly appreciated,” comments Haklander.

Henderson explains: “One of the positives to come from this project was that we were able to go ahead with a planned role for a permanent commissioning team. As projects get more complex and extend over longer periods, there is a need for greater consistency, and with this new development we are able to deliver an integrated resource constantly available to our customers.”

Netzsch/DXP partnership improves oil/water delivery system

0

When a well in an oilfield is first opened, generally there is plenty of existing pressure and volume for oil, gas and water to reach the surface. Over time, however, that initial boost reduces and artificial lift methods must be applied to literally push those resources to the surface. The most often used artificial lift methods include progressing cavity pumps (PCP), rod lift, plunger lift, gas lift, hydraulic lift, and electric submersible pumps (ESP). Each has particular strengths for specific applications.

Conventional pumping methods

Netzsch Pumps USA, in partnership with DXP, began a discussion with a Midwest oil producer that employed the gas lift method. The producer had just constructed a multi-pad well site having designed in the gas lift artificial lift method.

In this system, high pressure gas is injected into the well bore, which forces the fluids to the surface. Each well then feeds the gas and fluids to a dedicated two phase, horizontal separator, which divides a major portion of the gas from the well fluids. The gas is then directed back into the compressor to be re-injected into the well bore.

The liquids and residual gas (not separated in the initial phase) are sent to a vertical, two phase separator for additional processing. The residual gas rises to the top of the separator and is fed back to the compressor. The fluids consisting of oil, water and some solids are then forced into the pumping system to be transported through pipelines to a central processing facility (CPF) where the oil is now separated from the water. The CPF is approximately 15 miles from the well site.

Unreliability of conventional technology

To date, the most common method to move the fluids to the CPF has been the use of centrifugal pumps. However, in this case several issues are encountered when using centrifugal technology:

  • Inability to handle the varying suction and discharge pressures and maintain consistent flow rates.
  • Inability to handle the viscosity fluctuations and maintain consistent flow rates.
  • Inability to handle solids that may be present in the fluids without extreme wear.

Centrifugal pumps are unable to maintain constant flows when suction pressures vary. This is also the case when discharge pressures fluctuate. In order to provide consistent flow rates, control valves and other instrumentation must be used to insure the centrifugal pump is operating at its best efficiency point (BEP). If not, the flows drop off substantially reducing production.

Viscosity fluctuations are challenging for centrifugal pumps because flow output is affected. For instance, as viscosity increases the flow rate of a centrifugal pump will begin to rapidly decrease, and production rates are reduced.

The high speed impeller rotation of centrifugal pumps cannot handle solids or abrasives without accelerated wear. Because of the high speeds (3,600 RPM) solids and abrasives can cause rapid wear of the impellers, resulting in reduced production and high maintenance costs.

Nemo PC pumps address issues

Netzsch Nemo PC pumps can manage fluctuations in suction and discharge pressures while maintaining a consistent flow rate. Variations in viscosity of the pumped fluid do not affect the flow rates, allowing production to continue at the highest levels required.

Pump speeds are controlled by VFDs to meet production flow rates. PC pumps can meet the pressure demands over the wide speed range.

Netzsch Nemo PC pumps can handle solids and abrasives that could be present in the fluid with very little wear. This is because there is low internal leakage (slip) inside the pumping elements which is the result of the properly sized compression fit between the rotor and stator.

To meet the application conditions provided by the producer (7,500 bpd/51 m3/h per pump, up to 250 psi/1.7 bar suction pressures, differential pressure of 500 psi/3.4 bar) Netzsch engineers selected the Nemo pump model NM076SY. Since a total capacity of up to 30,000 bpd/204 m3/h was required from the three wells, Netzsch recommended the use of four pumps.

The Netzsch Nemo pump was supplied with SAE 316SS materials and a Nemolast S459/S91 stator.

One of the things that sets Netzsch apart from other progressing cavity pump manufacturers is the ability to offer many different universe joint options to meet demanding pumping applications. In this case, Netzsch engineers recommended the Z type joint. The Z double seal pivot joint is used when flows and pressures are high and when torque and axial loads are at their highest. This joint is oil-filled and hermetically sealed with two independent seals that are resistant and compatible to both the lubricant and the pumped fluid. It is designed for continuous, heavy duty operation under the highest loads.

The joint also has a special design with a balanced seal. The balanced seal is referred to as an equalizer. The equalizer is a sliding piston that sits in the tube coupling rod and applies pressure on the lubrication oil at the same rate the seal is pressurized from the outside. This balanced seal design is able the handle suction pressures up to 1,000 psi/69 bar.

Netzsch, in partnership with DXP, supplied a complete, heavy duty I-beam skid, consisting of the pump, motor, gearbox, pressure gauges and sensors, and valves. All four pumps were installed and anchored in for smooth operation.

Engineers from DXP and Netzsch were present to ensure a smooth start-up and they have been in daily operation since.

Netzsch says that the producer has been very satisfied with the performance of the Netzsch pumps and the service and support of the Netzsch/DXP partnership. More units have been purchased and Netzsch pumps are being planned on future well sites to transport the produced water/oil mixture to central processing facilities.

Blend welds like a master with Superflex

Welding, an art that has been around for centuries, has come a long way since its invention. From the early days of blacksmiths hammering metal together to modern-day welding machines, it’s evident how technology has revolutionized this craft. But what about blending welds?

The Superflex abrasive range from Grinding Techniques is a versatile and affordable solution for all your welding needs. It offers a wide variety of products that include an extensive range for surface preparations that will turn anyone into an expert.

Welding is a joining process that permanently fuses materials together. A welder uses heat and pressure to join two pieces of metal or other materials together. The finished weld is known as a weldment or seam, leading onto the next process – achieving a seamless finish with our range of surface preparation abrasive products.

Blending welds is the action of combining two metal pieces together through welding and the grinding down of the weld to produce no visible seam.

Before welding can commence, the workpiece needs to be cleansed of any rust or mill scale that has formed.  The requirement for this application is ideally suited to the Superflex rough cleaning, or non-woven flap disc.  Once the cleaning process is completed you can determine the type of weld that is required.

There are many different welding processes, and each has its own advantages and disadvantages. The type of welding process that is best for a particular application depends on the materials to be joined, the thickness of the materials, the desired strength of the weld, the speed of the process, and the cost. Some common welding processes include MIG welding, also known as Gas Metal Arc Welding and TIG welding, known as Tungsten Inert Gas Welding. Where MIG welding is known to be a low cost yet highly productive method of welding, and mostly used on common metals like Carbon Steel and Alloys, TIG welding is a more precise form of welding and requires a bit more skill, as it results in a neater and smaller weld.

Carbon steel is almost always painted after welding, where Stainless steel usually requires a polished finish. If working on Carbon steel, not all welds need to be removed, as the seam will not always be visible. Stainless steel, like elevator panels, or handrails on the other hand requires a highly refined finish to disguise scratches.

When preparing to blend a weld, it is important to ensure that you are working with a clean, good weld, free from air bubbles or porosity. There should also be no undercut for example, edges that don’t intrude or fold into the surface of the material.

The Superflex range consists of different product options when it comes to blending weld applications. Removing the weld can quickly be accomplished with our Superflex AS30R Professional grinding disc for ease of application and minimal fuss.  We recommend, a criss-cross motion to knock down the high spots when grinding, as you will remove stock quicker and easier without damaging the workpiece around the weld.

It is important to refrain from too much pressure when using a grinding disc, as you wouldn’t want to grind into the weld causing damage that could potentially weaken the weld leading to it needing to be re-worked. In some cases, a used grinding disc might offer the perfect solution, as it will be less aggressive on application. It is important to note that the final required blend will require further rework with a finer grit abrasive product after grinding.

If opting to use only one product, the Industrial and Professional range of Superflex Flap Discs with a multitude of application possibilities on various material, is ideal to remove both the weld and produce the final blend.

As a third option to blend welds, Superflex Fibre Discs can be used. A P80 grit used at a really low grinding angle of about 45 degrees, will blend the weld perfectly. Once satisfied with the finish, you can use a finer grit fibre disc, we recommend either P120 or P150, to remove the scratch marks further. Take care not to use excessive pressure during this application.

The surface is now ready for painting, perfectly prepared using the Superflex range of surface preparation products, however if a mirror finish is required, we recommend using a Superflex Non-woven Medium Flap disc followed by a Superflex Non-woven Fine Flap disc.

Whatever your requirement when it comes to abrasive products, we have you covered.

Valves in the pulp and paper Industry

Valve supplier Bilfinger Intervalve Africa (BIA), investigated the steam system of a paper mill to allow for possible improvements that can be made. Top performers in the paper and pulp industry are constantly striving to increase productivity and quality while minimising costs. The main aspects that need to be addressed in achieving operational excellence are a reduction in energy costs, chemical use, production downtime and process variability.

“The correct selection, monitoring and servicing of control valves can result in financial rewards for clients,” he points out.

Underhill mentions that the functions of control valves in the paper and pulp industry are extremely diverse. They range from the required accuracy of the dosing valves, and the tight control and fast-acting requirements of the basis weight valve to the severe service requirements of the power and steam system such as the control of cavitation and noise.

Careful consideration should be given to the selection of a control valve, as the specific function which it needs to fulfil in sizing and style has to be considered, he states.

Underhill explains that the process of selecting the correct size, style and characteristics of a valve is paramount in the initial stages of a project. Incorrect sizing of the control valve could result in the valve not operating in a good control range, leading to the possibility of excessive wear and loss of controllability.

Certain valves have been specifically designed to operate in different applications – incorrect selection can lead to cavitation or flashing damage, excessive plant noise and poor control in areas such as basis weight, affecting paper quality. Valves used in incorrect applications can lead to undesirable process variability.

Control valve assembly consists of three prime components – the valve body, actuator and positioning. These components need to work in harmony with one another to fulfil the client’s control requirements. Poor performance of any of these components can lead to poor control of the process, leading to unacceptable process variability that can seriously affect the user’s bottom line, he explains.

The advent of the smart positioners on control valves, as well as emergency shutdown valves, have resulted in many benefits for the client, Underhill notes. The Fisher DVC2000 and DVC6200 series digital valve controllers add accuracy of the valve position along with valve diagnostic capabilities that will determine the health of the valve.

Using the downloaded information from the device, either from advanced diagnostics or the online performance diagnostics, allows for maintenance programmes to be adjusted to cater for the more problematic valves. This will avoid the removal and stripping of valves that are in good health, which is costly and time consuming, he explains.

Overlaying downloads obtained from valves over time will assist the client in moving to predictive maintenance and reducing expensive stock holding of spares.

In conjunction with control valves, it is important to be aware that good-quality, hand-operated or automated isolation valves should be used in certain applications to protect the control valve, Underhill says.

“Bilfinger Intervalve Africa has a wide range of quality products to fill this role,” he concludes.

Vesconite supplies 5000-unit blanket order

Vesconite Bearings is supplying a Georgia-based vertical-turbine pump manufacturer with a 5000-unit blanket wear-rings order, allowing the manufacturer to request low-friction Vesconite Hilube polymer wear rings for 10 of its vertical-turbine-pump models.

The company ordered its first Vesconite Hilube wear rings in 2015 and, after testing, started ordering larger quantities from 2017. In March 2019, Vesconite visited the pump manufacturer and finalised fixed volume requirements and pricing for the blanket order. The company supplies the central and south-eastern USA with pumps for the municipal, industrial, fire and flood-control industries.

The order covers a one-year period and allows the company to regularly draw on the 5000-unit blanket wear rings order. Vesconite Bearings technical sales representative, Charlie Simpson, said: “The company sees the value of using the product and has switched all of its wear rings to Vesconite Hilube ones in all of its own-brand vertical-turbine pumps.”

Vesconite Hilube wear rings allow for extremely close clearances to ensure greater pump efficiencies and are designed for use with mildly acidic or basic liquids.

SCHROEDAHL announces self-modulating TDL ARVs

SCHROEDAHL, a CIRCOR International brand has announced that new, self-modulating TDL Automatic Recirculation Valves (ARVs) are now available in cast material that is more than 35% lighter.

The all-in-one pump protection solutions are designed to keep pumping systems running smoothly in firefighting, refinery, power and chemical applications without cavitation or overheating.

Unlike control valve packages, the self-operated flow-sensitive Schroedahl TDL Automatic Recirculation Valves operate without a separate power supply or any control system and begin protection as soon as they are installed.

The valves combine a high-quality main line check valve and the automatic bypass control system in a new, durable design. The valves’ self-actuated integrated bypass control function ensures minimum flow rate, guarding pumps against overheating and cavitation. The systems provide high pump stability with less vibration and fewer coupling or gear problems. TDL ARVs’ modulation bypass function also offers savings for operators with reduced energy consumption for frequent partial load operation.

Additionally, the bypass check valve prevents reverse pump flow, and allows for parallel pump installations.

The truth about the imminent copper supply crisis

The chief geoscientist with leading global mining-tech company IMDEX has issued a clarion call to the mining sector to restore its damaged image and shake off its risk-averse approach as he warned there was widespread ignorance of the scale of the imminent copper supply crisis.

Dr Dave Lawie, Chief Geoscientist and Chief Technologist – Mining Solutions with IMDEX, in an address to geoscience students for the University of British Columbia’s Earth, Ocean and Atmospheric Sciences Department, said the mining sector needed to effectively communicate its role in finding the metals and minerals, including copper, needed in a low-carbon future to address the copper supply crisis. Failure to do so risked the future of decarbonisation and accelerated electrification.

“I have a saying for our industry at the moment. It can’t read the label from inside the bottle. On the outside of the bottle it says, ‘save the world’, but we can’t read the label,” Dr Lawie said.

Finding enough copper to meet future copper supply crisis was a problem “that needs the best minds on the planet to think through.

“That’s the challenge for all of us. Living in a world where we need to talk to people about what the mining industry and geoscience need to do to address the copper supply crisis and save the world is very difficult when I read a survey that says kids think milk comes from a supermarket.

“So, if they think that, try asking them where the copper comes from for their iPhone. “They won’t know; they just won’t have thought of that as a concept. But that’s not their problem. That is our problem.

“We are an incredibly bad industry at communicating with the general public about the copper supply crisis. Terrible, abysmal.”

In a wide-ranging presentation, Dr Lawie compared the likely future demand/supply scenarios for critical minerals to meet net-zero emission targets to those for copper.

“Solar and wind would have to grow 20 to 30 times to deliver the amount of electrification the US needs to decarbonise by 2050 or go carbon neutral by 2050. When I see that I think where is the copper going to come from?” Dr Lawie said.

“To supply the demand for electrify electric vehicles by 2040 we’ll need 42 times the amount of lithium, 25 times more graphite, 21 times more cobalt, 11 times more nickel and seven times more rare earths than we are producing now.

“Now I only find that mildly disturbing because when I look at those commodities I think: Lithium no one’s looked for seriously – ever – and in fact we can find new lithium. Lithium mines we can bring into production. We’re actually finding lots of lithium hard rock deposits at the surface in Australia.

“Australia has increased its hard rock lithium production immensely in just a matter of two or three years. We can respond; it doesn’t worry me at all. Same with graphite. We haven’t really seriously looked for graphite. We’ll fix that. Cobalt is an issue, particularly with mining in the Democratic Republic of Congo, but we can we find 20 times more cobalt, not a problem geologically.

“There are cobaltian pyrite deposits sitting at the surface all through the Curnamona Block in Australia. Increasingly, cobalt is being recovered as a byproduct of nickel laterite mining.”

Cobalt prices have declined this year amid a drop in demand, the possibility of a change in battery technology with less reliance on cobalt, and some miners increasing production.

“Lithium, nickel, cobalt, graphite, manganese, rare earths; don’t worry about it as a geoscientist, Dr Lawie said “Copper? Worry a lot because that is where the problem is going to come.”

He said declining copper grades meant more waste and increased use of water and power to maintain existing supply rates, but current copper mining rates were not enough to cover demand for existing uses without factoring in “the electrification of everything” in a low-carbon future.

Better data from ore body knowledge could help unlock some of the stranded copper assets worldwide that are not constrained by ESG issues. “Barrick has gone back into Reko Diq (gold and copper mine) on the border with Pakistan and Afghanistan.

That tells you something about the risk appetite and that the looming copper deficit is true. Some companies are really making the effort. That is a giant deposit. Given its geopolitical complexity, if it could be (released) it would be a big win for a copper supply of the future,” Dr Lawie said.

“In 2021, we used about 20 to 23 Mt of copper, but some projections have that demand going to 30 Mt by 2030. How on earth are we going to go from 22 Mt of copper to 30 Mt a year? “Kamoa-Kakula copper mine (in the DRC) is the largest mine that has come on line for some time and will produce half a million tonnes a year.

“We need two Kamoa’s a year for the next 10 to 15 years to supply the copper we need to decarbonise. Of those 22 Mt of copper, the four largest producers of it are Chile, Peru, Congo and China. None of those countries you would call great exemplars of democratic governance and stability.

“So, of the current supply, apart from the geological problems of securing more supply and putting it into production, the existing resources are under threat. This is a very finely balanced supply consumption equation.

“We can’t risk copper supply chain delays or our want and willingness to expand solar, and wind electricity production won’t happen.

“If you think that the industry is responding by ramping up exploration budgets massively and getting to work, it sort of is and isn’t. What we’re doing is within the realms of what our industry conventionally does in the face of these things which is not much actually because we’re still risk averse.

“Of course, the more political problems you have in a jurisdiction, the less likely you are to want to go out and spend $10 billion.

“As a reflection of our industry, about half the total global exploration expenditure still is spent on gold.

Next would be copper. The amount of exploration spending on copper is increasing, but not really anything that’s going to make a difference. “The message for my mining industry comrades is, I just wonder if our industry can actually do anything about this?”

Tanzania signs $667m of deals to develop rare earth and graphite projects

Tanzania has signed agreements worth a total of $667m with three Australian companies for the development of rare earth minerals and graphite projects, reported Reuters.

Signed with Evolution Energy Minerals, Ecograf and Peak Rare Earths, the agreements form part of Tanzania’s efforts to advance negotiations on long-delayed mining and energy projects.

Under the deals, the country will have a 16% stake in each of the jointly established companies to operate the rare earth and graphite projects, reported Reuters, citing Palamagamba Kabudi, the chairman of the Tanzanian Government’s negotiating team.

Evolution Energy Minerals has signed agreements related to the arrangements regarding the ownership and development of its Chilalo Graphite Project.

Evolution managing director Phil Hoskins said: “Completion of the agreements is a key milestone as we continue to progress towards the development of our Chilalo project.

“Financiers require certainty on the operation of the Tanzanian government’s free-carried interest and the completion of these agreements provides the certainty to support further investment from Evolution and debt and equity financiers.”

EcoGraf has signed an agreement with the Tanzanian government for the development and operation of the Epanko Graphite Project.

According to the deal, the new Duma TanzGraphite joint venture has been incorporated to develop and operate the Epanko project.

EcoGraf holds an 84% stake in Duma TanzGraphite while the government owns a 16% free-carried interest.

Peak Rare Earths has signed a binding framework agreement with the government for the development of the Ngualla Rare Earth Project.

Peak executive chair Russell Scrimshaw said: “Development of the Ngualla Project will deliver direct foreign investment of more than $320m into the Tanzanian economy, generate hundreds of direct and thousands of indirect jobs for Tanzanians and position Tanzania as one of the major rare earth producers outside of China.”

CLEAN AND COLOURFUL.

The special challenges faced by the food and pharmaceutical industries result from the wide diversity of their processes. Success depends on the consistency and continuity of the production processes – whether it be mixing, filling, evaporating or CIP and SIP cleaning. That’s why longevity and reliability are also in the focus when selecting measurement technology components. An industrial metrology specialist is now introducing new compact and simple instrument series consisting of pressure sensors and level switches that bring colour into play.

TAILORED TO STANDARD APPLICATIONS

VEGA has now completed its measurement technology portfolio for hygiene-sensitive processes with 2 new compact instrument series comprising pressure sensors and level switches. The product families VEGABAR and VEGAPOINT prove that automation can be quite simple and highly efficient at the same time, without compromising on dependability, hygiene or accuracy. The new measuring instruments are perfectly tailored to standard applications that nevertheless do not tolerate compromises when it comes to quality. Their standardised  hygienic adapter system (see info box) provides flexibility and helps keep installation work and parts inventory at a reasonable level. The process fittings can be selected as needed and adapted to local requirements.

READY FOR CLEANING

All surfaces of sensors that come into contact with the product are made of stainless steel and have optimal surface roughness values. All materials across the board are approved and tested according to FDA and EC 1935/2004. This is confirmed by independent laboratories and institutes. The design of the instruments is certified according to the European EHEDG guidelines and the North American 3-A Sanitary Standards Inc.

Vega sensors reliably withstand the complex CIP and SIP processes and ensure in every process step that all required media are continuously available in sufficient quantities.

SWITCHING STATUS VISIBLE AT A GLANCE

Thanks to the all-round switching status display, all switching states can be visually discerned from any direction. The colour of the illuminated ring, which can be freely selected from over 256 colours, remains clearly visible even in daylight. The plant operator can see at a glance if the measuring process is running, if the sensor is switching or if there is a possible malfunction in the process.

UNIVERSAL COMMUNICATION VIA IO-LINK

There is a lot of sensor intelligence built right into the new compact series: The standard IO-Link protocol ensures universal and, at the same time, particularly simple communication. This means that the instruments have a standardised  communication platform that enables seamless data transfer and simple integration of the system. With this tool, sensors can be installed, parameterised and, if necessary, put back into operation faster and more cost-effectively. IO-Link transfers parameters automatically if an instrument has to be exchanged.

WIRELESS TRANSMISSION OF MEASURED VALUES

The new VEGABAR and VEGAPOINT instrument series can be easily read out and configured via Bluetooth with a smartphone or tablet. Radio technology is making processes more flexible. Wireless communication provides better accessibility. It allows parameterisation, display and diagnostics from a distance of up to 25 meters, thus saving time and avoiding dangers. Especially in environments such as clean rooms, where physical access involves a lot of effort, setup and operation become considerably easier.

COMBINATION AS REQUIRED

VEGABAR pressure sensors with switching function are available in three versions: the compact series 10 and the series 20 and 30, each with or without a display, a switching point visualization and a large graphic display. The instruments are available with either a metallic or a ceramic measuring cell.

VEGAPOINT sensors for point level detection are also available in three versions. Two of them (10 and 20) are designed for liquids with a water content of at least 10%, the third (30) can also be used for bulk solids.

The new pressure sensors and level switches represent an important milestone for VEGA. Users not only get an entire range of level and pressure measurement technology from a single source, but also hygiene-optimised instrument designs that are extremely easy to install and a needs-based combination of reliability, flexibility and reproducibility in food and pharmaceutical processes.
