Abstract

A method is disclosed for recovering a useful gas from a gas mixture including a useful gas and at least one secondary gas. The gas mixture is first compressed and transferred into a pressure vessel where cooling occurs. Then, from the pressure vessel, a secondary-gas containing gas phase is removed and condensed useful gas is transferred into a purification vessel. In the purification vessel, the condensed useful gas is then purified. A plant is disclosed for recovering a useful gas from a gas mixture. Finally, the use of a plant for carrying out a method for recovering a useful gas from a gas mixture is disclosed.
