Rising to the salt extraction challenge

A salt extraction operation had to transfer rapidly from an onshore to an offshore web site supplied by 5 km of pipework. The firm turned to flow control companion Celeros to help meet the unique circumstances encountered on the new salt properly.
Overview of the two 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 brought online ahead of schedule, preventing a potential halt in production when the prevailing onshore nicely developed points. Frisia Zout BV, part of K+S Minerals and Agriculture GmbH, was able to overcome the time and technical challenges of accelerating the project by working in partnership with Celeros Flow Technology (Celeros FT).
The bulk of the salt produced by Frisia Zout BV goes loose to a forty,000-tonne storage facility for supply in bulk to trade. The remainder is packed in smaller portions for use in food production or made into cubes for water purification.
The salt is extracted underneath licence from the Dutch authorities. The existing 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 model new borehole and related plant was required at the Frisia Zout BV web 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 existing extraction licence expired at the finish of 2021. However, unexpected difficulties arose with the prevailing onshore properly, which meant that production 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 turned crucial to convey the brand new offshore nicely onstream as quickly as possible.
Time pressures were not the one challenges the corporate faced. Due to the natural geology, the extraction path to the model new offshore resource was not a straight bore: it modified path twice earlier than reaching the salt deposits. In reality, the model 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 end result, the method water must be pumped in at excessive pressure (250 barg) and at a high move rate (450 m3/h) to extract the quantity of salt required, making the selection of pumps crucial to success.
Total resolution
Frisia Zout BV has an extended and established relationship with Celeros FT via the ClydeUnion Pumps brand, based mostly not only on the prime quality of ITS OEM pumps but in addition on its capacity to respond rapidly to any operational points. ราคาเกจวัดแรงดันน้ำ turned to its trusted circulate management companion as quickly as once more for help in assembly the distinctive circumstances encountered on the new salt well.
Celeros FT model ClydeUnion Pumps assessed the flow requirements for the water injection course of on the new plant and verified that CUP-BB3 pumps might be made to satisfy requirements. The pumps had been specified with Duplex stainless-steel casings because they’d be working in a salt-laden setting. Celeros FT manufactured, provided, installed and commissioned the mission-critical pumps for injecting water into the new offshore salt cavern, assembly unusual requirements for prime pressure and excessive move 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 obligation necessities.
Jouk Riemer, project supervisor for Frisia Zout BV, defined: “We have used CUP-BB3 pumps prior to now and located that their multistage centrifugal design provides better efficiency, in comparability with plunger pumps, for this utility. We needed to use them again for the new project. The Celeros FT staff responded to the challenges magnificently, utilizing their engineering experience to establish one of the best answer to fulfill the pressure and move rates we required, delivering the pump skids to meet the new construction schedule and serving to us maintain the challenge on monitor.”
Future assured
The new salt extraction plant got here on-line in December 2020. Its CUP-BB3 pumps meet the excessive strain and flow charges required for the application and can run in parallel, which has improved productiveness. The availability of a spare pump provides extra confidence that production downtime shall be minimal. The company’s capability to satisfy the accelerated project deadline is especially impressive when you consider that the Covid-19 pandemic was already affecting provides of materials and parts. The Celeros FT staff worked onerous to make certain that this did not have any influence on their buyer.
Celeros FT also supplied specialist engineering experience throughout the set up and commissioning section and will proceed to ensure the pumps operate satisfactorily throughout the plant’s 15-year lifespan, although the pump constructing could also be required to serve multiple well in future as demand for K+S excessive purity salt continues to grow. Easy substitute of damage parts and ongoing service support from Celeros FT will be positive that the BB3 pumps continue to fulfill operational parameters all through the extraction plant’s lifetime.
Riemer stated: “The combination of prime of the range OEM gear and practical engineering skills supplied by Celeros Flow Technology was instrumental in delivering this venture forward of time. I’m satisfied it will have taken a lot longer to get what we required from another pump manufacturer. The company’s responsiveness was essential in meeting our revised deadline, reducing prices and maintaining extraction at this website viable.” Riemer concluded: “This is the first offshore extraction well we have developed nevertheless it has been a largely positive experience thanks to Celeros Flow Technology. They introduced invaluable engineering expertise and specialist pump data to this challenge and are a fundamental a half of its success.”
