LNG BOG(Boil off gas)compressor’s main role is to keep the pressure of the LNG tank within required range. Boil off gas enters into the suction line of the compressor, is compressed and sent either to a condenser for re-liquefaction, fed into a gas turbine as fuel in a power generation plant, or is directed into a pipeline for city gas usage. Gas suction temperature is cryogenic, down to -160 degC(-256degF) therefore special considerations and high precision during its design and manufacturing are necessary.
We developed the world’s first LNG BOG Reciprocating Compressor in 1969. Since then, IHI’s highly acclaimed delivery track record allowed our LNG BOG Reciprocating Compressors to hold dominating share of the market.
