Abstract
The installation comprises an insulated storage tank (1) containing the gas in at least partially liquid form at a high pressure, a line (2) comprising a vaporizer (3) for supplying gas to a user station (A), a first cold-holding circuit (4), comprising a valve (5) and a first exchanger (6) in heat-exchange contact with the fluid in the first tank (1), and a pressure-holding line (8) comprising a second exchanger (9) and a valve (10). The system is particularly useful as a backup installation for a main gas-production source (30).
Claims6
An installation for supplying a gas under high pressure to at least one user station, comprising an insulated tank for storing the gas in at least partially liquid form at a pressure greater than 10.times.10.sup.5 Pa, having an upper part and a lower part, at least one supply line comprising an evaporator and extending between the lower part of the tank and the user station, a first fluid circuit extending between the lower part of the tank and an outer circuit portion comprising, serially arranged, an ON/OFF valve, and a first heat exchanger in heat exchange relationship with the fluid within the tank to thereby keep the tank cold.
The installation as claimed in 1, wherein the storage pressure in the tank is greater than the critical pressure of the gas.
The installation as claimed in 1, wherein the gas is oxygen nitrogen.
The installation as claimed in 1, wherein the gas is oxygen.
