摘要： A system and method of pre-purification of a feed gas stream is provided that is particularly suitable for pre-purification of a feed air stream in cryogenic air separation unit. The disclosed pre-purification systems and methods are configured to remove substantially all of the hydrogen, carbon monoxide, water, and carbon dioxide impurities from a feed air stream and is particularly suitable for use in a high purity or ultra-high purity nitrogen plant. The pre-purification systems and methods preferably employ two or more separate layers of hopcalite catalyst with the successive layers of the hopcalite separated by a zeolite adsorbent layer that removes water and carbon dioxide produced in the hopcalite layers.

摘要： Adsorptive decomposition of a gas mixture is performed by vacuum pressure swing adsorption. The gas mixture is condensed to the adsorption pressure by means of at least one condenser prior to being fed into the vacuum pressure swing adsorption process. Regeneration of the adsorber(s) is carried out by means of at least one vacuum pump. The condensed gas mixture (1, 5, 6) is at least periodically and/or at least partially temporarily stored (S1) and/or fed to a consumer at those times when no gas mixture is being fed to the vacuum pressure swing adsorption process; and/or at least one of the vacuum pumps (P) that is not required for the regeneration is used at least occasionally for another application at those times when no regeneration of the adsorber or an adsorber (A, A′) is being carried out.
