Rising to the salt extraction challenge

A salt extraction operation needed to move rapidly from an onshore to an offshore web site provided by 5 km of pipework. The firm turned to circulate control partner Celeros to assist meet the unique circumstances encountered on the new salt well.
Overview of the two new water injection pumps for single and parallel operation, following installation and commissioning at the Frisia Zout BV site.
A new salt extraction plant off the north coast of Holland has been brought on-line ahead of schedule, preventing a possible halt in manufacturing when the existing onshore nicely developed points. 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 unfastened to a forty,000-tonne storage facility for supply in bulk to trade. The remainder is packed in smaller portions to be used in food production or made into cubes for water purification.
The salt is extracted under licence from the Dutch government. The present borehole licence
allowed K+S to extract salt from underground on the mainland. Due to regulatory modifications, the brand new licence would solely permit extraction from subsea sources off the coast. Consequently, a new borehole and associated plant was required at the Frisia Zout BV web site.
New challenges
K+S began planning for a brand new pump building in 2017, and construction started in April 2020 with the goal of bringing it onstream earlier than the prevailing extraction licence expired at the finish of 2021. However, unforeseen difficulties arose with the present onshore nicely, which meant that production would cease before anticipated. To bridge the gap, Frisia Zout BV began bringing in salt water by tanker, but this was an expensive different. As digital pressure gauge ราคา , it grew to become crucial to convey the new offshore properly onstream as quickly as possible.
Time pressures were not the only challenges the corporate confronted. Due to the pure geology, the extraction path to the brand new offshore useful resource was not a straight bore: it modified course twice earlier than reaching the salt deposits. In truth, the brand new plant is fed by one of the deepest wells on the earth and has 5 km of pipework past the water injection pumps. As a end result, the method water needs to be pumped in at excessive strain (250 barg) and at a excessive move rate (450 m3/h) to extract the amount of salt required, making the choice of pumps crucial to success.
Total answer
Frisia Zout BV has a protracted and established relationship with Celeros FT by way of the ClydeUnion Pumps brand, primarily based not only on the prime quality of ITS OEM pumps but also on its capacity to reply quickly to any operational issues. The company turned to its trusted flow control associate as quickly as once more for assist in assembly the unique circumstances encountered on the new salt properly.
Celeros FT model ClydeUnion Pumps assessed the circulate necessities 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 as a outcome of they would be working in a salt-laden surroundings. Celeros FT manufactured, supplied, put in and commissioned the mission-critical pumps for injecting water into the new offshore salt cavern, assembly unusual requirements for high stress and excessive move charges. 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 make sure it met the new obligation requirements.
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 better performance, in comparison with plunger pumps, for this application. We wanted to make use of them again for the brand new challenge. The Celeros FT team responded to the challenges magnificently, using their engineering expertise to identify the best solution to fulfill the stress and circulate rates we required, delivering the pump skids to meet the new building schedule and helping us maintain the venture on observe.”
Future assured
The new salt extraction plant came on-line in December 2020. Its CUP-BB3 pumps meet the high stress and circulate charges required for the application and might run in parallel, which has improved productivity. The availability of a spare pump provides further confidence that production downtime shall be minimal. The company’s capability to satisfy the accelerated venture deadline is especially impressive when you suppose about that the Covid-19 pandemic was already affecting provides of materials and components. The Celeros FT group worked hard to ensure that this didn’t have any impression on their customer.
Celeros FT additionally offered specialist engineering expertise all through the installation and commissioning part and can proceed to make sure the pumps operate satisfactorily all through the plant’s 15-year lifespan, although the pump constructing could also be required to serve a couple of properly in future as demand for K+S high purity salt continues to grow. Easy replacement of damage parts and ongoing service assist from Celeros FT will be certain that the BB3 pumps proceed to satisfy operational parameters all through the extraction plant’s lifetime.
Riemer said: “The mixture of high quality OEM gear and practical engineering abilities supplied by Celeros Flow Technology was instrumental in delivering this venture forward of time. I’m satisfied it would have taken lots longer to get what we required from one other pump producer. The company’s responsiveness was crucial in meeting our revised deadline, decreasing prices and maintaining extraction at this website viable.” Riemer concluded: “This is the primary offshore extraction well we’ve developed however it has been a largely constructive experience thanks to Celeros Flow Technology. They introduced invaluable engineering experience and specialist pump data to this project and are a basic part of its success.”
