Abstract

Method and apparatus for treating a gas by adsorption. A gas is compressed and then treated by being circulated in an adsorber. A regenerating fluid is indirectly heated by the gas coming from the compressor. In a second regeneration phase, the regenerating fluid is sent directly to the adsorber, while the treated gas is refrigerated by an auxiliary refrigerator.
