Atlas Copco Gas and Process Division has adapted its turbocompressor 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 over conventional technologies, the company claimed.
Using cryogenic low pressure BOG and fuel gas boosting reference machinery, Atlas Copco has designed a compressor that handles cryogenic high pressure BOG applications with greater reliability and efficiency than was previously attainable.
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 company said.
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 machines are known for, now in cryogenic high pressure BOG handling.”
