Rising to the salt extraction problem

A salt extraction operation needed to transfer shortly from an onshore to an offshore website supplied by 5 km of pipework. The company turned to circulate control 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 installation and commissioning at the Frisia Zout BV web site.
A new salt extraction plant off the north coast of Holland has been brought on-line ahead of schedule, stopping a possible halt in manufacturing when the present onshore properly 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 supply in bulk to industry. The remainder 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 existing borehole licence
allowed K+S to extract salt from underground on the mainland. Due to regulatory adjustments, the brand new licence would only allow 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 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 prevailing onshore nicely, which meant that manufacturing would cease ahead of anticipated. To bridge the gap, Frisia Zout BV started bringing in salt water by tanker, but this was an costly various. As a end result, it grew to become imperative to convey the brand new offshore well onstream as quickly as possible.
Time pressures weren’t the one challenges the corporate confronted. Due to the natural geology, the extraction route to the brand new offshore resource was not a straight bore: it modified direction twice before reaching the salt deposits. In reality, the 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 result, the process water must be pumped in at high stress (250 barg) and at a high move rate (450 m3/h) to extract the amount of salt required, making the selection of pumps critical to success.
Total solution
Frisia Zout BV has an extended and established relationship with Celeros FT by way of the ClydeUnion Pumps brand, based mostly not only on the prime quality of ITS OEM pumps but in addition on its ability to respond quickly to any operational points. The firm turned to its trusted flow control associate as quickly as again for assist in meeting the unique circumstances encountered on the new salt nicely.
Celeros FT brand ClydeUnion Pumps assessed the circulate requirements for the water injection process at the new plant and verified that CUP-BB3 pumps might be made to meet necessities. The pumps have been specified with Duplex stainless-steel casings as a outcome of they’d be operating 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, meeting uncommon necessities for high stress and excessive flow rates. 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 new duty necessities.
Jouk Riemer, challenge manager for Frisia Zout BV, explained: “We have used CUP-BB3 pumps in the past and found that their multistage centrifugal design provides higher performance, in comparability with plunger pumps, for this application. We wanted to use them once more for the brand new challenge. The Celeros FT staff responded to the challenges magnificently, utilizing their engineering experience to identify the best solution to meet the stress and circulate rates we required, delivering the pump skids to fulfill the new development schedule and serving to us hold the project on observe.”
Future assured
The new salt extraction plant came online in December 2020. Its CUP-BB3 pumps meet the high stress and circulate rates required for the applying and might run in parallel, which has improved productiveness. เกจวัดแรงดันnuovafima of a spare pump gives further confidence that manufacturing downtime shall be minimal. The company’s ability to fulfill the accelerated project deadline is particularly spectacular when you consider that the Covid-19 pandemic was already affecting provides of supplies and components. The Celeros FT group labored exhausting to ensure that this did not have any impact on their customer.
Celeros FT additionally supplied specialist engineering expertise throughout the set up and commissioning section and will proceed to ensure the pumps operate satisfactorily all through the plant’s 15-year lifespan, although the pump building could additionally be required to serve multiple properly in future as demand for K+S high purity salt continues to grow. Easy alternative of damage elements and ongoing service help from Celeros FT will ensure that the BB3 pumps continue to satisfy operational parameters throughout the extraction plant’s lifetime.
Riemer stated: “The combination of prime quality OEM tools and practical engineering skills offered by Celeros Flow Technology was instrumental in delivering this venture forward of time. I’m satisfied it would have taken so much longer to get what we required from one other pump manufacturer. The company’s responsiveness was essential in meeting our revised deadline, lowering costs and keeping extraction at this site viable.” Riemer concluded: “This is the primary offshore extraction properly we now have developed nevertheless it has been a largely positive experience because of Celeros Flow Technology. They brought invaluable engineering experience and specialist pump information to this venture and are a fundamental a part of its success.”
