Abstract: Method for extracting a gas from a gas mixture by: during a purification step, bringing a first sorption medium into contact with the gas mixture in order to extract the gas from the gas mixture, whereby an enriched first sorption medium is formed in which the gas is at least partially sorbed; during a regeneration step, bringing a second sorption medium into contact with the enriched first sorption medium in order to extract the gas from the enriched liquid first sorption medium; whereby for the contact in the purification step and/or in the regeneration step use is made of a separate venturi ejector.
