Abstract

Separating a starting gas mixture using pressure swing adsorption. In this, at least part of a low-pressure extraction flow from the pressure swing adsorption is subjected to a thermal separation, wherein a return fraction is formed in the thermal separation which is returned to the pressure swing adsorption separation. In the thermal separation, counterflow cooling takes place to obtain a two-phase mixture, wherein at least part of the two-phase mixture is subjected to phase separation to obtain a gas phase and a condensate. At least a part of the gas phase is used to form the return fraction, and counterflow cooling is carried out using at least a part of the gas phase and at least a part of one or more fluid flows which are formed by expansion of at least a part of the liquid phase.
