Rising to the salt extraction challenge

A salt extraction operation needed to transfer quickly from an onshore to an offshore web site equipped by 5 km of pipework. The company turned to move control associate Celeros to help meet the distinctive circumstances encountered at the new salt properly.
Overview of the 2 new water injection pumps for single and parallel operation, following set up and commissioning at the Frisia Zout BV web site.
A new salt extraction plant off the north coast of Holland has been brought on-line ahead of schedule, preventing a possible halt in production when the present onshore nicely developed points. Frisia Zout BV, a part of K+S Minerals and Agriculture GmbH, was in a place to overcome the time and technical challenges of accelerating the challenge by working in partnership with Celeros Flow Technology (Celeros FT).
The bulk of the salt produced by Frisia Zout BV goes unfastened to a 40,000-tonne storage facility for delivery in bulk to industry. The the rest is packed in smaller quantities to be used in meals manufacturing or made into cubes for water purification.
The salt is extracted underneath licence from the Dutch authorities. The current borehole licence
allowed K+S to extract salt from underground on the mainland. Due to regulatory modifications, the new licence would solely permit extraction from subsea sources off the coast. Consequently, a new borehole and associated plant was required at the Frisia Zout BV web site.
New challenges
K+S began planning for a brand new pump constructing in 2017, and development started in April 2020 with the goal of bringing it onstream earlier than the present extraction licence expired on the finish of 2021. However, unforeseen difficulties arose with the existing onshore well, which meant that production would cease sooner than anticipated. To bridge the hole, Frisia Zout BV started bringing in salt water by tanker, but this was an expensive different. As a end result, it grew to become imperative to deliver the new offshore properly onstream as quickly as possible.
Time pressures were not the only challenges the corporate faced. Due to the pure geology, the extraction path to the model new offshore useful resource was not a straight bore: it modified course twice before reaching the salt deposits. In fact, the new plant is fed by one of many deepest wells on the planet and has 5 km of pipework past the water injection pumps. As a end result, the method water must be pumped in at high stress (250 barg) and at a excessive move fee (450 m3/h) to extract the quantity of salt required, making the choice of pumps important to success.
Total resolution
Frisia Zout BV has an extended and established relationship with Celeros FT via the ClydeUnion Pumps model, based mostly not solely on the high quality of ITS OEM pumps but additionally on its ability to reply rapidly to any operational points. The company turned to its trusted move control associate as soon as again for help in meeting the distinctive circumstances encountered at the new salt properly.
Celeros FT brand ClydeUnion Pumps assessed the move requirements for the water injection course of at the new plant and verified that CUP-BB3 pumps might be made to fulfill requirements. The pumps had been specified with Duplex stainless-steel casings as a result of they might be operating in a salt-laden environment. Celeros FT manufactured, equipped, installed and commissioned the mission-critical pumps for injecting water into the brand new offshore salt cavern, assembly uncommon necessities for high pressure and excessive flow rates. In addition, they supported Frisia Zout BV in bringing an older pump again into service as a spare: assessing it and upgrading the casing to make sure it met the model new obligation requirements.
Jouk Riemer, challenge supervisor for Frisia Zout BV, defined: “We have used CUP-BB3 pumps up to now and found that their multistage centrifugal design provides better performance, compared to plunger pumps, for this software. We wished to make use of them once more for the new challenge. The Celeros FT group responded to the challenges magnificently, using their engineering experience to identify one of the best resolution to satisfy the strain and flow rates we required, delivering the pump skids to meet the new building schedule and serving to us maintain the challenge on monitor.”
Future assured
The new salt extraction plant came online in December 2020. Its CUP-BB3 pumps meet the excessive pressure and move rates required for the appliance and can run in parallel, which has improved productivity. เกจวัดแก๊ส of a spare pump provides additional confidence that production downtime will be minimal. The company’s capability to satisfy the accelerated venture deadline is especially spectacular when you consider that the Covid-19 pandemic was already affecting supplies of supplies and parts. The Celeros FT staff labored exhausting to make sure that this didn’t have any impact on their customer.
Celeros FT additionally offered specialist engineering experience throughout the set up and commissioning section and will proceed to make sure the pumps function satisfactorily throughout the plant’s 15-year lifespan, although the pump building may be required to serve multiple properly in future as demand for K+S high purity salt continues to grow. Easy alternative of damage elements and ongoing service assist from Celeros FT will be positive that the BB3 pumps proceed to fulfill operational parameters all through the extraction plant’s lifetime.
Riemer said: “The combination of top of the range OEM equipment and practical engineering abilities supplied by Celeros Flow Technology was instrumental in delivering this project forward of time. I’m convinced it will have taken lots longer to get what we required from one other pump manufacturer. The company’s responsiveness was essential in assembly our revised deadline, decreasing costs and preserving extraction at this web site viable.” Riemer concluded: “This is the first offshore extraction nicely we now have developed but it has been a largely optimistic experience due to Celeros Flow Technology. They introduced invaluable engineering experience and specialist pump information to this venture and are a elementary part of its success.”
