ABSTRACT:
A pressure swing adsorption process with six adsorbers is operated with only one adsorber in an adsorption phase. The adsorbers pass through switching cycles wherein, following an adsorption phase, there are conducted four- or five-stage coccurent expansions, then a countercurrent expansion, a scavenging with cocurrent expansion gas, and a multistage pressurizing to the adsorption pressure. In this process, three or four pressure equalization stages are provided.
