A method for gas processing, in particular for processing biogas of a biogas plant in which in one method step a membrane process or a reactive process is executed, and in at least one further method step an adsorption and/or absorption process is executed.

Method and device for gas processing

A method for separating off carbon dioxide from a gas mixture, in particular from breathing air, with a life-sustaining device, wherein in a first method step the gas mixture is fed to an adsorption and/or absorption unit under at least one first pressure, and in a second method step a gas mixture is conveyed out of the adsorption and/or absorption unit under at least one second pressure that is higher than the first pressure.

A method for separating off carbon dioxide in biogas plants includes an adsorption phase and a regeneration phase. Crude biogas that is treated in the adsorption phase is passed at ambient pressure through an adsorber suitable for adsorption of carbon dioxide, and in the regeneration phase the adsorber is regenerated with a purge gas at the temperature between 20 and 100&#xb0; C., and also ambient pressure. The crude biogas is treated upstream of the carbon dioxide separation method, and is desulphurized and dried and minor components can be removed. For avoiding impurities in the biogas, at the start of the adsorption phase a purge process is carried out on the adsorber with treated crude biogas, wherein the purge process is controlled with respect to time via a number of valves and a sensor.

A method for removing volatile organic substances from the contained air of closed habitats includes a) conducting contained air through an adsorber bed formed by a hydrophobic zeolite bed, b) closing the adsorber bed, c) extracting the air from the adsorber bed and feeding the air into the closed habitat, d) desorbing the volatile organic substances, in particular freons such as R134a and VOCs, from the adsorber bed by heating the adsorber, e) leading the desorbed substances to an environment outside the closed habitat, wherein water vapor, water, or COis fed to the adsorber bed through a flushing line. The device includes a housing for accommodating an adsorber, a contained-air supply line, a contained-air return line, a flushing line, and least one outlet-air line for returning air from the adsorber bed into the closed habitat and for conducting the desorbate to an environment outside the closed habitat.

A method for regenerating an adsorber or absorber on board a submarine, wherein the adsorber or absorber is present in the interior of the submarine for binding metabolically generated CO-containing harmful gases, and wherein the metabolically generated CO-containing harmful gases are transferred outboard via a compressor. The thermal energy for regenerating the adsorber or absorber is generated by burning a hydrocarbonaceous energy carrier with oxygen, wherein at least one combustion product, together with the metabolically generated CO-containing harmful gases, is transferred outboard via the compressor.
