Rising to the salt extraction problem

A salt extraction operation had to transfer shortly from an onshore to an offshore site equipped by 5 km of pipework. The company turned to circulate management associate Celeros to help meet the unique circumstances encountered at the new salt nicely.
Overview of the two new water injection pumps for single and parallel operation, following set up and commissioning at the Frisia Zout BV website.
A new salt extraction plant off the north coast of Holland has been brought on-line forward of schedule, preventing a possible halt in production when the prevailing onshore properly 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 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 supply in bulk to trade. The the rest is packed in smaller quantities to be used in food 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 allow extraction from subsea sources off the coast. Consequently, a brand 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 construction started in April 2020 with the aim of bringing it onstream earlier than the existing extraction licence expired at the end of 2021. However, unexpected difficulties arose with the present onshore nicely, which meant that production would stop before anticipated. To bridge the hole, Frisia Zout BV started bringing in salt water by tanker, however this was an costly various. As a end result, it turned imperative to convey the new offshore properly onstream as soon as possible.
Time pressures weren’t the one challenges the company confronted. Due to the pure geology, the extraction path to the brand new offshore useful resource was not a straight bore: it modified path twice before reaching the salt deposits. In fact, the model 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 outcome, the process water has to be pumped in at high strain (250 barg) and at a high move fee (450 m3/h) to extract the quantity of salt required, making the choice of pumps crucial to success.
Total resolution
Frisia Zout BV has an extended and established relationship with Celeros FT via the ClydeUnion Pumps brand, primarily based not only on the top quality of ITS OEM pumps but in addition on its capability to respond shortly to any operational issues. The firm turned to its trusted circulate control companion once again for help in meeting the distinctive circumstances encountered on the new salt nicely.
Celeros FT brand ClydeUnion Pumps assessed the circulate requirements for the water injection process on the new plant and verified that CUP-BB3 pumps might be made to meet necessities. The pumps were specified with Duplex stainless-steel casings because they’d be working in a salt-laden setting. Celeros FT manufactured, supplied, installed and commissioned the mission-critical pumps for injecting water into the brand new offshore salt cavern, assembly unusual requirements for high pressure and high flow 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 ensure it met the model new duty 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, compared to plunger pumps, for this utility. We needed to make use of them again for the model new challenge. The Celeros FT team responded to the challenges magnificently, utilizing their engineering expertise to determine the best resolution to satisfy the pressure and move rates we required, delivering the pump skids to meet the brand new building schedule and helping us keep the challenge on track.”
Future assured
The new salt extraction plant got here online in December 2020. Its CUP-BB3 pumps meet the excessive stress and circulate rates required for the applying and may run in parallel, which has improved productivity. The availability of a spare pump provides additional confidence that manufacturing downtime shall be minimal. The company’s capacity to fulfill the accelerated venture deadline is especially impressive when you assume about that the Covid-19 pandemic was already affecting supplies of materials and parts. The Celeros FT staff worked exhausting to ensure that this did not have any impact on their buyer.
Celeros FT also offered specialist engineering experience 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, though the pump constructing could additionally be required to serve a couple of nicely in future as demand for K+S excessive purity salt continues to develop. Easy replacement of wear parts and ongoing service help from Celeros FT will be positive that the BB3 pumps proceed to satisfy operational parameters all through the extraction plant’s lifetime.
เกจ์วัดแรงดันน้ำมันเครื่อง said: “The mixture of prime of the range OEM gear and practical engineering skills offered by Celeros Flow Technology was instrumental in delivering this venture ahead of time. I’m convinced it will have taken a lot longer to get what we required from another pump producer. The company’s responsiveness was crucial in assembly our revised deadline, reducing prices and keeping extraction at this website viable.” Riemer concluded: “This is the primary offshore extraction well we now have developed nevertheless it has been a largely constructive expertise due to Celeros Flow Technology. They introduced invaluable engineering expertise and specialist pump information to this project and are a fundamental part of its success.”
