| 摘要 |
The invention relates to a process for purifying and drying, by adsorption, gas mixtures, in particular air upstream of air fractionation plants. The adsorbers for this purpose are provided with two packed beds, the first of which binds the water and the second of which binds the component to be separated off from the gas stream. The process is carried out in such a way that the heat of adsorption formed during the adsorption is for the most part retained in the adsorber in order to serve for supporting the desorption in the following regeneration.
