Drawing from their experience manufacturing integrally geared turbocompressors (IGC) for the LNG market, Atlas Copco Gas and Process Division has adapted this technology to handle cryogenic high-pressure boil off gas (BOG) processing. This six-stage compressor offers over 98% reliability and availability combined with significant CAPEX and OPEX savings.
This is the first process machine to combine two cryogenic and four warm stages on a single gearbox and skid, allowing for a smaller, more efficiently operating machine. The six stages allow for high processing capability.
The application of dry-gas seals in a cryogenic high-pressure BOG centrifugal compressor is another first for this type of machine. Compared to traditional carbon ring seals, the dry gas seals allow for higher efficiency and lower methane leakage into the environment.
“Applying integral gear technology to cryogenic high pressure BOG handling is a true accomplishment by our engineering team”, said Tushar Patel, Global Head of Marketing at Atlas Copco Gas and Process. “We are pleased that we can offer our customers the efficiency and reliability our IGC ma-chines are known for, now in cryogenic high pressure BOG handling”.
Atlas Copco Gas and Process will be holding an announcement for the HP BOG compressor in their booth (#M280) at Gastech on 17 September 2019.
