Abstract
The present invention relates to a method of and a cryogenic installation for distributing gases. From a storage tank at low pressure, successive portions of cryogenic liquid are withdrawn to an enclosure, which is isolated by closing a valve. After this, a further valve is opened, the effect of which is to cause the pressure in a receptacle to rise to the high distribution pressure and to allow the gas concerned to condense to a certain degree so that said enclosure is filled with liquid under pressure. The liquid evaporates partially at the periphery and is thus transferred to a heater and from there to a buffer container. The invention is applicable in particular to the distribution of oxygen, nitrogen and argon under pressure.
