A reliable flow of high-purity nitrogen
29 April 2022
When an oil refinery in the UK required the supply of nitrogen to its tank farm to purge one of its storage tanks, they turned to Atlas Copco Specialty Rental. The customer had previously used liquid nitrogen and vaporizers to supply the tanks, however they were keen to explore an alternative, tailored, and efficient solution. We were only too happy to help.
Purity combo: N2 and oil-free air
The customer’s requirement was to provide 650m3/h nitrogen at 95% purity. We had the perfect total solution in our NGM 1000 nitrogen membrane unit combined with the PTS 1600, our oil-free diesel-driven air compressor, which delivered 100% oil-free feed air to the nitrogen membrane.
The location of the tank also called for a compact solution as there was limited space in which to site the equipment. For this we proposed our safety trailer to house the NGM 1000 and nitrogen receiver. This enabled us to position the equipment where required and erect the safety platform and handrails to enable access around the unit for commissioning and servicing.
After installation and commissioning, the setup was ready to supply nitrogen to the tank at the required specification. The overall aim was to achieve oxygen levels of less than 10% within the tank. The first test results showed that the levels in the tank had dropped to 8.3% oxygen content which was a great start. The final test results, however were even better; with oxygen levels down to 6%. This gave the customer confidence in the knowledge that the environment within the tank was inert.
