Atlas Copco to introduce new BOG handling solution at Gastech

LNG Industry,

Atlas Copco Gas and Process has announced that it will introduce a new approach to cryogenic high-pressure boil-off gas (BOG) handling at Gastech 2019.

According to the statement, the company will draw upon its experience in manufacturing integrally geared turbocompressors (IGC) for the LNG market, adapting this technology to handle cryogenic high-press BOG processing. This six-stage compressor reportedly offers over 98% reliability and availability, as well as combined CAPEX and OPEX savings.

Using cryogenic low pressure BOG and fuel gas boosting reference machinery, Atlas Copco Gas and Process claims that it has developed a compressor capable of handling cryogenic high pressure BOG applications with greater reliability and efficiency than was previously attainable.

According to the company, 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 the industry’s highest 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.

Tushar Patel, Global Head of Marketing at Atlas Copco Gas andProcess, said: “Applying integral gear technology to cryogenic high pressure BOG handling is a true accomplishment by our engineering team.

“We are pleased that we can offer our customers the efficiency and reliability our IGC machines are known for, now in cryogenic high pressure BOG handling.”
