摘要:
High and low pressure pumping systems for cryogenic or liquefied gases comprise at least one cryogenic tank (1) in which the liquefied cryogenic gas is stored at low pressure and at least one vaporizer (2) which is connected to the gas offtake region located downstream of the system. The systems comprise: at least one insulated tank (S; S1) which is interposed between a cryogenic tank (1) and a vaporizer (2); valves (V1, V2, V; V1, V3, V13) for connecting the tank (S; S1) to the tank (1) and valves (V3, V4; V2, V4) for connecting the tank (S; S1) to the vaporizer (2).
