Rising to the salt extraction challenge

A salt extraction operation needed to transfer quickly from an onshore to an offshore website provided by 5 km of pipework. The firm turned to circulate control companion Celeros to assist meet the distinctive circumstances encountered at the new salt well.
Overview of the 2 new water injection pumps for single and parallel operation, following set up and commissioning on 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 possible halt in manufacturing when the existing onshore nicely developed issues. Frisia Zout BV, a half of K+S Minerals and Agriculture GmbH, was able to 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 free to a 40,000-tonne storage facility for delivery in bulk to trade. เกจไนโตรเจนsumo is packed in smaller portions to be used 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 new licence would only permit extraction from subsea sources off the coast. Consequently, a model new borehole and associated plant was required on the Frisia Zout BV site.
New challenges
K+S began planning for a new pump building in 2017, and building began in April 2020 with the goal of bringing it onstream before the present extraction licence expired on the end of 2021. However, unforeseen difficulties arose with the prevailing onshore well, which meant that manufacturing would cease before anticipated. To bridge the gap, Frisia Zout BV started bringing in salt water by tanker, but this was an costly different. As a result, it grew to become crucial to bring the brand new offshore nicely onstream as quickly as possible.
Time pressures weren’t the only challenges the company faced. Due to the pure geology, the extraction path to the new offshore resource was not a straight bore: it changed path twice before reaching the salt deposits. In truth, the brand new plant is fed by one of many deepest wells on the earth and has 5 km of pipework beyond the water injection pumps. As a outcome, the method water must be pumped in at excessive pressure (250 barg) and at a high move price (450 m3/h) to extract the quantity of salt required, making the selection of pumps critical to success.
Total answer
Frisia Zout BV has a long and established relationship with Celeros FT by way of the ClydeUnion Pumps brand, primarily based not only on the high quality of ITS OEM pumps but additionally on its ability to respond quickly to any operational points. The company turned to its trusted move control partner as quickly as once more for help in meeting the unique circumstances encountered on the new salt nicely.
Celeros FT model ClydeUnion Pumps assessed the move necessities for the water injection process 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 as a outcome of they’d be operating in a salt-laden surroundings. Celeros FT manufactured, equipped, put in and commissioned the mission-critical pumps for injecting water into the new offshore salt cavern, meeting unusual necessities for high stress and excessive 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 requirements.
Jouk Riemer, project manager for Frisia Zout BV, explained: “We have used CUP-BB3 pumps up to now and located that their multistage centrifugal design offers better efficiency, compared to plunger pumps, for this utility. We wished to use them again for the model new project. The Celeros FT group responded to the challenges magnificently, using their engineering experience to identify the most effective resolution to fulfill the stress and circulate rates we required, delivering the pump skids to fulfill the brand new construction schedule and helping us hold the project on track.”
Future assured
The new salt extraction plant got here online in December 2020. Its CUP-BB3 pumps meet the excessive pressure and move charges required for the appliance and might run in parallel, which has improved productiveness. The availability of a spare pump offers additional confidence that production downtime shall be minimal. The company’s capability to meet the accelerated challenge deadline is particularly impressive when you think about that the Covid-19 pandemic was already affecting supplies of supplies and parts. The Celeros FT team labored onerous to guarantee that this didn’t have any influence on their customer.
Celeros FT also supplied specialist engineering experience all through the set up and commissioning section and can proceed to ensure the pumps operate satisfactorily throughout the plant’s 15-year lifespan, although the pump building may be required to serve more than one nicely in future as demand for K+S excessive purity salt continues to develop. Easy replacement of damage parts and ongoing service assist from Celeros FT will be certain that the BB3 pumps proceed to meet operational parameters all through the extraction plant’s lifetime.
Riemer said: “The combination of prime of the range OEM tools and practical engineering abilities offered by Celeros Flow Technology was instrumental in delivering this challenge forward of time. I’m convinced it would have taken a lot longer to get what we required from one other pump manufacturer. The company’s responsiveness was crucial in meeting our revised deadline, reducing prices and maintaining extraction at this site viable.” Riemer concluded: “This is the first offshore extraction properly we’ve developed however it has been a largely constructive expertise thanks to Celeros Flow Technology. They brought invaluable engineering experience and specialist pump data to this venture and are a fundamental a half of its success.”
