Lng Bog Compressor

Lng Bog Compressor FAQ

What is an lng bog boil off gas compressor?

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.

What is the use of a bog compressor?

BOG compressor is commonly found in natural gas chemical industry used for extraction of boil off gas (BOG) from LNG tanks. After heating, the BOG will be boosted to desired pressure based on different processes and then transported to other processing equipment. This can effectively avoid over-high pressure in the LNG tanks.

Can a boil off gas compressor be used to recycle lng?

The boil-off gas (BOG) compressor is widely used for recycling the excessive boil-off gas of liquefied natural gas (LNG), and the extra-low suction temperature brings about great challenges to design of the BOG compressor. In this paper, a test system was built to

What is the operating temperature of the ihi lng bog compressor?

IHI LNG BOG Compressor design point is set to ultra-low temperatures (in the vicinity of -160 degC/-256degF). However, during start-up of a compressor, suction gas can warm up to ambient temperatures due to gas which stagnates in piping etc..
