A salt extraction operation needed to move shortly from an onshore to an offshore website supplied by 5 km of pipework. The company turned to circulate management associate Celeros to help meet the unique circumstances encountered on the new salt well.
Overview of the 2 new water injection pumps for single and parallel operation, following installation and commissioning at the Frisia Zout BV web site.
A new salt extraction plant off the north coast of Holland has been introduced online ahead of schedule, stopping a potential halt in production when the present onshore properly developed points. 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 loose to a 40,000-tonne storage facility for supply in bulk to business. The remainder is packed in smaller quantities for use in meals manufacturing or made into cubes for water purification.
The salt is extracted underneath licence from the Dutch government. The current borehole licence

allowed K+S to extract salt from underground on the mainland. Due to regulatory adjustments, the new licence would only allow extraction from subsea sources off the coast. Consequently, a model new borehole and associated plant was required at the Frisia Zout BV web site.
New challenges

K+S started planning for a model new pump building in 2017, and building started in April 2020 with the aim of bringing it onstream earlier than the prevailing extraction licence expired on the finish of 2021. However, unexpected difficulties arose with the prevailing onshore properly, which meant that manufacturing would cease ahead of anticipated. To bridge the hole, Frisia Zout BV began bringing in salt water by tanker, however this was an costly alternative. As diaphragm seal , it turned crucial to bring the new offshore nicely onstream as soon as possible.
Time pressures were not the only challenges the company faced. Due to the pure geology, the extraction route to the new offshore useful resource was not a straight bore: it modified course twice earlier than reaching the salt deposits. In truth, the new plant is fed by one of many deepest wells on the planet and has 5 km of pipework beyond the water injection pumps. As a outcome, the process water needs to be pumped in at excessive stress (250 barg) and at a excessive flow fee (450 m3/h) to extract the amount of salt required, making the selection of pumps important to success.
Total resolution

Frisia Zout BV has a long and established relationship with Celeros FT through the ClydeUnion Pumps brand, based not solely on the high quality of ITS OEM pumps but in addition on its ability to reply quickly to any operational issues. The company turned to its trusted flow control partner as soon as again for assist in meeting the unique circumstances encountered on the new salt well.
Celeros FT brand ClydeUnion Pumps assessed the move requirements for the water injection process at the new plant and verified that CUP-BB3 pumps could be made to meet requirements. The pumps have been specified with Duplex stainless-steel casings because they’d be working in a salt-laden surroundings. Celeros FT manufactured, supplied, installed and commissioned the mission-critical pumps for injecting water into the brand new offshore salt cavern, assembly uncommon requirements for prime pressure and high circulate 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 ensure it met the brand new obligation necessities.
Jouk Riemer, project manager for Frisia Zout BV, explained: “We have used CUP-BB3 pumps up to now and found that their multistage centrifugal design gives higher efficiency, in comparability with plunger pumps, for this application. 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 determine the best resolution to fulfill the pressure and move rates we required, delivering the pump skids to fulfill the brand new development schedule and helping us hold the challenge on monitor.”

Future assured

The new salt extraction plant came online in December 2020. Its CUP-BB3 pumps meet the excessive strain and circulate rates required for the applying and may run in parallel, which has improved productivity. The availability of a spare pump provides further confidence that manufacturing downtime shall be minimal. The company’s ability to fulfill the accelerated project deadline is especially impressive when you suppose about that the Covid-19 pandemic was already affecting provides of supplies and parts. The Celeros FT staff labored exhausting to ensure that this didn’t have any impact on their buyer.
Celeros FT additionally supplied specialist engineering experience all through the installation and commissioning phase and will proceed to ensure the pumps operate satisfactorily throughout the plant’s 15-year lifespan, although the pump constructing could additionally be required to serve more than one properly in future as demand for K+S excessive purity salt continues to develop. Easy alternative of damage components and ongoing service assist from Celeros FT will be certain that the BB3 pumps proceed to fulfill operational parameters all through the extraction plant’s lifetime.
Riemer stated: “The mixture of high quality OEM tools and sensible engineering expertise provided by Celeros Flow Technology was instrumental in delivering this challenge ahead of time. I’m convinced it will have taken so much longer to get what we required from another pump producer. The company’s responsiveness was crucial in assembly our revised deadline, lowering costs and maintaining extraction at this web site viable.” Riemer concluded: “This is the primary offshore extraction nicely we now have developed but it has been a largely constructive expertise due to Celeros Flow Technology. They introduced invaluable engineering expertise and specialist pump data to this project and are a basic part of its success.”
