Rising to the salt extraction challenge

A salt extraction operation had to move quickly from an onshore to an offshore web site supplied by 5 km of pipework. The company turned to circulate control companion Celeros to help meet the unique circumstances encountered on the new salt nicely.
Overview of the 2 new water injection pumps for single and parallel operation, following set up and commissioning on the Frisia Zout BV site.
A new salt extraction plant off the north coast of Holland has been brought online forward of schedule, preventing a possible halt in production when the prevailing onshore nicely developed points. Frisia Zout BV, a part of K+S Minerals and Agriculture GmbH, was in a position to overcome the time and technical challenges of accelerating the venture by working in partnership with Celeros Flow Technology (Celeros FT).
The bulk of the salt produced by Frisia Zout BV goes free to a 40,000-tonne storage facility for delivery in bulk to trade. The the rest is packed in smaller portions for use in meals manufacturing or made into cubes for water purification.
The salt is extracted beneath licence from the Dutch authorities. The existing borehole licence
allowed K+S to extract salt from underground on the mainland. Due to regulatory adjustments, the model new licence would solely allow extraction from subsea sources off the coast. Consequently, a new borehole and associated plant was required at the Frisia Zout BV site.
New challenges
K+S started planning for a brand new pump constructing in 2017, and construction started in April 2020 with the goal of bringing it onstream earlier than the existing extraction licence expired at the end of 2021. However, unforeseen difficulties arose with the prevailing onshore properly, which meant that manufacturing would cease sooner than anticipated. To bridge the hole, Frisia Zout BV started bringing in salt water by tanker, however this was an expensive various. As a end result, it became imperative to deliver the new offshore properly onstream as quickly as attainable.
Time pressures weren’t the only challenges the company faced. Due to the natural geology, the extraction path to the new offshore useful resource was not a straight bore: it modified path twice before reaching the salt deposits. In fact, the new plant is fed by one of the deepest wells on the earth and has 5 km of pipework beyond the water injection pumps. As a result, the process water has to be pumped in at high strain (250 barg) and at a excessive move price (450 m3/h) to extract the amount of salt required, making the selection of pumps critical to success.
Total resolution
Frisia Zout BV has a long and established relationship with Celeros FT by way of the ClydeUnion Pumps model, based mostly not only on the high quality of ITS OEM pumps but additionally on its capability to reply shortly to any operational points. The company turned to its trusted move management associate as soon as once more for assist in meeting the distinctive circumstances encountered on the new salt well.
Celeros FT model ClydeUnion Pumps assessed the flow requirements for the water injection course of at the new plant and verified that CUP-BB3 pumps could be made to meet necessities. The pumps have been specified with Duplex stainless-steel casings as a end result of they might be working in a salt-laden setting. Celeros FT manufactured, supplied, put in and commissioned the mission-critical pumps for injecting water into the new offshore salt cavern, meeting uncommon necessities for high strain and high circulate charges. In addition, they supported Frisia Zout BV in bringing an older pump back into service as a spare: assessing it and upgrading the casing to make sure it met the brand new duty necessities.
Jouk Riemer, venture manager for Frisia Zout BV, explained: “We have used CUP-BB3 pumps up to now and located that their multistage centrifugal design gives higher performance, in comparability with plunger pumps, for this software. ราคาเกจวัดแรงดันลม needed to use them again for the model new project. The Celeros FT team responded to the challenges magnificently, using their engineering experience to identify one of the best solution to meet the strain and move charges we required, delivering the pump skids to fulfill the new development schedule and serving to us hold the venture on observe.”
Future assured
The new salt extraction plant got here on-line in December 2020. Its CUP-BB3 pumps meet the high strain and flow charges required for the appliance and may run in parallel, which has improved productivity. The availability of a spare pump gives further confidence that production downtime shall be minimal. The company’s ability to satisfy the accelerated project deadline is particularly spectacular when you consider that the Covid-19 pandemic was already affecting provides of supplies and components. The Celeros FT staff worked exhausting to ensure that this didn’t have any impression on their buyer.
Celeros FT additionally offered specialist engineering experience throughout the set up and commissioning part and will proceed to ensure the pumps operate satisfactorily throughout the plant’s 15-year lifespan, though the pump building could also be required to serve multiple nicely in future as demand for K+S high purity salt continues to develop. Easy replacement of wear elements and ongoing service help from Celeros FT will make positive that the BB3 pumps continue to meet operational parameters all through the extraction plant’s lifetime.
Riemer stated: “The combination of high quality OEM equipment and sensible engineering skills offered by Celeros Flow Technology was instrumental in delivering this project forward of time. I’m satisfied it will have taken lots longer to get what we required from another pump producer. The company’s responsiveness was crucial in meeting our revised deadline, reducing prices and keeping extraction at this site viable.” Riemer concluded: “This is the first offshore extraction nicely we have developed but it has been a largely optimistic experience thanks to Celeros Flow Technology. They brought invaluable engineering expertise and specialist pump data to this venture and are a elementary part of its success.”
