Abstract
The invention relates to a method for the provision of gas under pressure, by vaporisation of a cryogenic liquid from at least two cryogenic separation devices (A, B, C, D). Each device comprises a heat exchanger () and a system of columns (). In a first mode of operation, a cryogenic liquid is withdrawn from the columns in each cryogenic separation device, at least a part of which is pressurised () to give a pressurised cryogenic liquid () and at least a part of the cryogenic liquid under pressure is vaporised in the heat exchanger () to give a part of gas under pressure (). A cryogenic liquid is sent () from the cryogenic separation device to a common store () and at least one liquid (A,B,C,D) coming from the store is vaporised in the exchange line () in at least one of the cryogenic separation devices.
