Rising to the salt extraction challenge

A salt extraction operation needed to transfer quickly from an onshore to an offshore web site equipped by 5 km of pipework. The firm turned to move control associate Celeros to assist meet the unique circumstances encountered at the new salt nicely.
Overview of the 2 new water injection pumps for single and parallel operation, following set up and commissioning at the Frisia Zout BV site.
A new salt extraction plant off the north coast of Holland has been introduced on-line forward of schedule, preventing a potential halt in production when the prevailing 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 venture by working in partnership with Celeros Flow Technology (Celeros FT).
The bulk of the salt produced by Frisia Zout BV goes unfastened to a 40,000-tonne storage facility for supply in bulk to industry. The remainder is packed in smaller quantities 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 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 site.
New challenges
K+S started planning for a brand new pump building in 2017, and development began in April 2020 with the aim of bringing it onstream earlier than the prevailing extraction licence expired on the finish of 2021. However, เกจวัดแรงดันแก๊สหุงต้ม arose with the prevailing onshore nicely, which meant that manufacturing would stop sooner than anticipated. To bridge the hole, Frisia Zout BV started bringing in salt water by tanker, however this was an costly different. As a outcome, it grew to become crucial to deliver the brand new offshore nicely onstream as quickly as potential.
Time pressures were not the one challenges the company faced. Due to the natural geology, the extraction route to the new offshore useful resource was not a straight bore: it changed direction twice earlier than reaching the salt deposits. In reality, the model new plant is fed by one of the deepest wells on the planet and has 5 km of pipework beyond the water injection pumps. As a end result, the process water has to be pumped in at high stress (250 barg) and at a high flow rate (450 m3/h) to extract the quantity of salt required, making the selection of pumps important to success.
Total resolution
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 also on its capability to respond shortly to any operational points. The firm turned to its trusted circulate control companion as soon as again for assist in meeting the distinctive circumstances encountered at the new salt nicely.
Celeros FT brand ClydeUnion Pumps assessed the flow necessities for the water injection process at the new plant and verified that CUP-BB3 pumps could probably be made to satisfy necessities. The pumps had been specified with Duplex stainless-steel casings as a outcome of they might be operating in a salt-laden environment. Celeros FT manufactured, supplied, installed and commissioned the mission-critical pumps for injecting water into the new offshore salt cavern, meeting unusual necessities for prime strain and high 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 ensure it met the new responsibility requirements.
Jouk Riemer, venture supervisor for Frisia Zout BV, defined: “We have used CUP-BB3 pumps in the past and found that their multistage centrifugal design gives higher efficiency, in comparison with plunger pumps, for this application. We needed to use them again for the model new challenge. The Celeros FT group responded to the challenges magnificently, using their engineering experience to determine the best solution to fulfill the stress and flow rates we required, delivering the pump skids to meet the brand new development schedule and helping us keep the venture on monitor.”
Future assured
The new salt extraction plant got here on-line in December 2020. Its CUP-BB3 pumps meet the high stress and move rates required for the application and can run in parallel, which has improved productiveness. The availability of a spare pump gives extra confidence that production downtime shall be minimal. The company’s capacity to fulfill the accelerated project deadline is particularly impressive when you consider that the Covid-19 pandemic was already affecting supplies of supplies 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 all through the installation and commissioning phase and will proceed to make sure the pumps function satisfactorily all through the plant’s 15-year lifespan, although the pump building may be required to serve multiple well in future as demand for K+S high purity salt continues to develop. Easy substitute of damage elements and ongoing service help from Celeros FT will make certain 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 tools and practical engineering expertise provided by Celeros Flow Technology was instrumental in delivering this venture ahead of time. I’m satisfied it would have taken lots longer to get what we required from another pump producer. The company’s responsiveness was crucial in meeting our revised deadline, reducing prices and keeping extraction at this website viable.” Riemer concluded: “This is the first offshore extraction properly we’ve developed nevertheless it has been a largely positive expertise because of Celeros Flow Technology. They brought invaluable engineering expertise and specialist pump data to this project and are a fundamental part of its success.”
