Problems solved by technology

[0013] These known techniques are bulky and cause a pressure loss of the gas
Since such a gas then has to be compressed, such a pressure loss results in a significantly higher compression energy

Embodiment Construction

[0040] figure 1 The device 1 shown in refers to a device for extracting gas from a gas mixture supplied by a supply line 2 .

[0041] The device 1 comprises a circuit 3 to which a supply line 2 is connected, in which the liquid first adsorption medium is flowed in the direction of arrow P from the first accumulator 4 via the first duct 5 through the second accumulator 6 and via the second The tubing circulates back to the first reservoir 4 .

[0042] This first adsorption medium, when in contact with the gas mixture, exhibits the property of being able to adsorb (for example by absorption or adsorption) the gas to be extracted from said gas mixture, so that, for example, the partial pressure of the gas to be extracted in the first adsorption medium is lower than that of the gas to be extracted. The partial pressure of a gas in a gas mixture.

[0043] The aforementioned circuit 3 comprises two consecutive stages in flow direction P, which are respectively a purification stage...

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 (12,22).

Description

technical field [0001] The invention relates to a method for extracting a gas from a gas mixture containing the gas. Background technique [0002] Such methods are known in the field of purification of raw biogas originating, for example, from anaerobic digestion of waste sludge, organic waste, manure and the like. The untreated biogas is mainly composed of methane and typically 30% to 50% CO 2 composed of gases. [0003] In order to be used as a natural gas alternative fuel and injected into the natural gas pipeline network, the CO in the untreated biogas must be removed as much as possible. 2 . The purified gas is therefore also known as green gas or biomethane because it does not contribute to global warming when it is burned, as opposed to what happens when fossil fuels are burned. [0004] A method is known in which by combining untreated biogas with adsorbed CO 2 Adsorption of gaseous nature The untreated biogas is purified by contact with an adsorption medium in ...
