An installation 2 for the storage and supply of a cryogenic liquefied gas, for example liquefied natural gas, comprises storage tank 4 for the liquefied gas at low temperature having an upper internal region 4a in which the boil off gas collects. That boil off gas is supplied by pipe 10 to an inlet 8 of a liquid jet pump or liquid jet compressor 6. Liquefied gas is conveyed from the tank 4 by pump 22 and pipe 20 to a jet 14 of the jet compressor 6. The boil off gas is entrained by the cold liquefied gas leaving the jet 14 in a venturi 16 to form a stream, the pressure of which is higher than that of the supply pressure of the vaporised gas so that the gas resumes its liquid phase, and the liquefied gas is raised to high pressure by high pressure pump 30 for onward supply. |
