| 摘要 |
An adiabatic adsorption method for pressure-swing adsorbers, e.g. for gas purification or separation of components of a gas mixture, in which several switchable adsorbers are used in an adsorption phase followed by at least two pressure-relief stages and at least one pressure buildup stage with an intervening purging in the adsorption-desorption/regeneration cycle. According to the invention, at least one of the adsorbers is operated as an auxiliary adsorber by comparison with a main adsorber with a reduced contact time between the adsorption medium and gases in the auxiliary adsorber. This reduced contact time can result from a reduced adsorption-phase period by comparison with that of the main adsorber (reduced residence time) and/or by using a reduced charge of the adsorption medium in the auxiliary adsorber by comparison with that of the main adsorber. |
