Abstract

A fluid storage and supply device comprising a cryogenic reservoir for storing liquefied fluid, a withdrawing circuit comprising a first withdrawing pipe having a first upstream end connected to the upper part of the reservoir and a second downstream end intended to be connected to a user member, the first withdrawing pipe comprising a first heating heat exchanger situated outside the reservoir and a second heating heat exchanger situated inside the reservoir, the withdrawing circuit comprising a set of valve(s) configured to ensure the passage of a flow of fluid circulating from the first end towards the second end by passing through the first heat exchanger and then through the second heat exchanger or by passing solely through the first heat exchanger without passing through the second heat exchanger, characterized in that the device further comprises a system for pressurizing the reservoir comprising a pressurizing pipe separate from the withdrawing circuit and comprising two ends respectively connected to the upper and lower parts of the reservoir, a vaporizing heat exchanger and a set of valve(s) configured to allow the withdrawal of liquid from the reservoir, the heating thereof in the vaporizing heat exchanger and the reintroduction thereof into the reservoir.

Dependent claims

A fluid storage and supply device comprising:

a cryogenic tank for storing liquefied fluid;
a withdrawal circuit comprising:
a first withdrawal line having a first, upstream end connected to the upper part of the tank and a second, downstream end intended to be connected to a user member, wherein the first withdrawal line comprises a first heating heat exchanger located outside the tank and a second heating heat exchanger located inside the tank;
an assembly of one or more valves that is configured to ensure the passage of a flow of fluid circulating from the first end to the second end, in the process entering the first heat exchanger and then the second heat exchanger or in the process entering solely the first heat exchanger without entering the second heat exchanger;
a system for pressurizing the tank, comprising:
a pressurization line separate from the withdrawal circuit and comprising two ends connected respectively to the upper part and the lower part of the tank,
a vaporization heat exchanger and
an assembly of one or more valves that is configured to allow liquid to be withdrawn from the tank, to be heated in the vaporization heat exchanger and to be reintroduced into the tank, and
wherein the first heat exchanger and the vaporization heat exchanger are housed in one and the same exchanger housing in a heat-exchange relationship with at least one flow of heat-transfer fluid.
