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.

A device for intermediate storage of condensation water includes a swirl body which causes an inflowing air-water mixture to rotate, and a venturi tube through which the air-water mixture leaves the device. A ring groove in which water accumulates because of the swirl is arranged downstream of the swirl body, and water accumulated in the ring groove is sucked into the venturi tube via one more suction pipes. An expansion zone has an expanded cross-section and a step shaped interior for generating increased surface adhesion. Separating metal sheets in the expansion zone brake the swirl, bind the accumulated gushing water by adhesion forces, and guide it by capillary forces to the interior surface of the expansion zone. Gushing water accumulated at the ends of the separating metal sheets is drained by one or more suction pipes, into the venturi tube.
