What is the working principle of the BOG compressor?

Answer:

General BOG compressor uses oil-free lubrication reciprocating compressor, the working principle is the same as the ordinary reciprocating compressor. The difference is that the inlet of the BOG compressor is low temperature gas, so the first stage cylinder block, piston and so on must be able to withstand low temperature, and also to prevent freezing
With the increase of volatile gas in the tank, the tank pressure rising, in order to maintain the pressure within the allowable range, the general need to BOG compression and then condensed into liquid or compressed output. The BOG compressor is the compressor used to compress the BOG
The working principle of BOG compressor is to use the connecting rod to push the piston to move again and again, so that the gas can be pressurized and transported out
Refers to cryogenic liquids, such as LNG (-162 degrees Celsius), low temperature propane (-40 ~ -42 degrees Celsius), low temperature alkane (0 ~ -2 degrees Celsius), etc., in the tank to absorb the heat outside the volatile gas
