Boil-Off Gas Generation in Vacuum-Jacketed Valve Used in Liquid Hydrogen Storage Tank
EnergiesThe boiling point of liquid hydrogen is very low, at −253 °C under atmospheric pressure, which causes boil-off gas (BOG) to occur during storage and transport due to heat penetration.

Experimental study on solubility of lubricating oils in a supercritical methane gas
International Journal of Naval Architecture and Ocean Engineering, 2022 In a Boil-off Gas (BOG) compressor, there could be a carryover phenomenon of lubricants oil which flows with a solvent gas. To protect process system downstream of the compressor, it is necessary to select low solubility lubricants at supercritical state.
