Rising to the salt extraction problem

A salt extraction operation needed to transfer rapidly from an onshore to an offshore website supplied by 5 km of pipework. The firm turned to circulate control partner Celeros to assist meet the distinctive circumstances encountered at the new salt properly.
Overview of the 2 new water injection pumps for single and parallel operation, following installation and commissioning on the Frisia Zout BV site.
A new salt extraction plant off the north coast of Holland has been introduced on-line ahead of schedule, stopping a potential halt in production when the existing onshore properly developed issues. Frisia Zout BV, a half of K+S Minerals and Agriculture GmbH, was capable of 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 forty,000-tonne storage facility for supply in bulk to business. The remainder is packed in smaller portions to be used in meals production or made into cubes for water purification.
The salt is extracted under licence from the Dutch authorities. The present borehole licence
allowed K+S to extract salt from underground on the mainland. Due to regulatory changes, the new licence would solely allow extraction from subsea sources off the coast. Consequently, a brand new borehole and associated plant was required on the Frisia Zout BV site.
New challenges
K+S started planning for a new pump constructing in 2017, and development started in April 2020 with the aim of bringing it onstream before the prevailing extraction licence expired at the finish of 2021. However, unforeseen difficulties arose with the prevailing onshore nicely, which meant that manufacturing would stop ahead of anticipated. To bridge the hole, Frisia Zout BV began bringing in salt water by tanker, however this was an expensive various. As a result, it grew to become crucial to deliver the model new offshore properly onstream as quickly as potential.
Time pressures were not the only challenges the company confronted. Due to the natural geology, the extraction path to the new offshore useful resource was not a straight bore: it modified path twice earlier than reaching the salt deposits. In fact, the new plant is fed by one of the deepest wells in the world and has 5 km of pipework past the water injection pumps. As a outcome, the method water needs to be pumped in at high strain (250 barg) and at a excessive move price (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 by way of the ClydeUnion Pumps brand, based mostly not solely on the prime quality of ITS OEM pumps but in addition on its capability to respond shortly to any operational issues. The company turned to its trusted flow control companion as soon as again for assist in meeting the distinctive circumstances encountered at the new salt well.
Celeros FT brand ClydeUnion Pumps assessed the flow necessities for the water injection course of on the new plant and verified that CUP-BB3 pumps might be made to meet requirements. The pumps have been specified with Duplex stainless-steel casings as a result of they might be working in a salt-laden environment. Celeros FT manufactured, equipped, put in and commissioned the mission-critical pumps for injecting water into the brand new offshore salt cavern, meeting uncommon necessities for high pressure and excessive move rates. 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 model new obligation necessities.
Jouk Riemer, project supervisor for Frisia Zout BV, defined: “We have used CUP-BB3 pumps in the past and located that their multistage centrifugal design offers better efficiency, in comparison with plunger pumps, for this application. We wished to make use of them once more for the brand new venture. The Celeros FT group responded to the challenges magnificently, utilizing their engineering expertise to establish one of the best resolution to fulfill the strain and move charges we required, delivering the pump skids to satisfy the new development schedule and serving to us keep the challenge on monitor.”
Future assured
The new salt extraction plant got here online in December 2020. Its CUP-BB3 pumps meet the high pressure and move charges required for the application and might run in parallel, which has improved productivity. The availability of a spare pump gives extra confidence that manufacturing downtime will be minimal. The company’s capacity to satisfy the accelerated venture deadline is particularly impressive when you consider that the Covid-19 pandemic was already affecting provides of supplies and components. The Celeros FT group labored onerous to guarantee that this didn’t have any impression on their buyer.
Celeros FT additionally supplied specialist engineering expertise all through the set up and commissioning section and can continue to make sure the pumps operate satisfactorily throughout the plant’s 15-year lifespan, although the pump constructing may be required to serve a couple of properly in future as demand for K+S excessive purity salt continues to grow. Easy alternative of wear components and ongoing service help from Celeros FT will ensure that the BB3 pumps continue to fulfill operational parameters throughout the extraction plant’s lifetime.
Riemer said: “The combination of excessive quality OEM gear and practical engineering expertise provided by Celeros Flow Technology was instrumental in delivering this project forward of time. I’m convinced it would have taken so much longer to get what we required from one other pump manufacturer. The company’s responsiveness was essential in assembly our revised deadline, reducing costs and maintaining extraction at this website viable.” เพรสเชอร์เกจน้ำ concluded: “This is the first offshore extraction well we’ve developed nevertheless it has been a largely optimistic experience due to Celeros Flow Technology. They introduced invaluable engineering expertise and specialist pump data to this venture and are a fundamental part of its success.”
