Abstract:
1. A method for the adsorptive decomposition of a gas mixture by means of a vacuum pressure swing adsorption process, wherein a gas mixture to be decomposed adsorptively is compressed to the adsorption pressure by means of at least one compressor before being delivered to the vacuum pressure swing adsorption process, and the regeneration of adsorber or adsorbers utilized in said vacuum pressure swing adsorption process occurs by means of at least one vacuum pump, and wherein at those times at which no gas mixture is delivered to the vacuum pressure swing adsorption process, the compressed gas mixture ( at those times at which no regeneration of the adsorber (A, A′) or of an adsorber (A, A′) by means of the vacuum pump (V) or at least one of the vacuum pumps (V) takes place, the vacuum pump (P) or at least one of the vacuum pumps (P) not required for regeneration is employed at least temporarily for another intended use.
