Abstract:
A method for purifying or separating a gas mixture comprising at least one fuel, using a unit having at least one adsorber subjected to a pressure cycle comprising at least one step of placing under vacuum by means of a vacuum pump, wherein at least one adsorber and/or the vacuum pump, depressurized during the cycle, is repressurized at least partly by an external gas to said unit and not containing a sufficient quantity of oxidizer to create an inflammable mixture during this repressurization.
