    摘要: An object of the present invention is to provide a pressure swing adsorption gas separation apparatus that can separate strong adsorbate components with high purity without allowing weak adsorbate components to contaminate the strong adsorbate component-storage tank. The present invention provides a pressure swing adsorption gas separation apparatus (100) including a raw material gas-storage tank (1) that stores a mixed gas of a target component and at least one component other than the target component as a raw material gas; a strong adsorbate component-storage tank (2) that stores strong adsorbate components; a weak adsorbate component-storage tank (3) that stores strong adsorbate components; a compressor (4) that compresses a gas of the raw material gas-storage tank (1) or the strong adsorbate component-storage tank (2); a compressor (5) that compresses a gas of the strong adsorbate component-storage tank (3); and four adsorption columns of a lower column (10B), lower column (1 1B), upper column (10U), and upper column (11U).

    摘要: Process for the recovery of helium from one or more than one helium-containing off-gas streams by successive preconditioning, cryogenic separation and purification, whereby the off-gas preconditioning takes place a multi-stage preconditioning unit 10, said preconditioning unit 10 comprising n stage units S1 to Sn, with n ≥ 2, each stage unit S1 to Sn being adapted to precondition off-gas by at least partially chemically converting at least one component other than helium in the off-gas and/or by at least partially removing at least one component other than helium from the off-gas, the stage units S1 to Sn being in linear fluid succession so that off-gas which has been preconditioned in stage unit Sx, with 1 ≤ x
