Abstract
A gas is purified by adsorption on activated carbon contained in an adsorber vessel. The carbon is desorbed by passing an inert gas therethrough at a sufficiently high temperature. The desorbed impurity is removed by refrigeration and the refrigeration is supplied by the vaporization of an inert gas in liquid phase. This vaporized inert gas, in turn, comprises the desorption gas.
