Аннотация:A mathematical model of the adsorption process in the adsorption stage of the system is proposed. The mathematical model has been tested on a binary mixture of nitrogen and oxygen used as an example. The data obtained by numerical simulation agree within the limits of error with experimental data obtained earlier. A scheme of a hybrid membrane–adsorption system for creating an artificial breathing atmosphere in a closed room, consisting of an adsorption unit in the first stage and a membrane unit in the second stage of separation, has been proposed. In the hybrid system, the feed stream drawn into the compressor comprises air from the external environment and air coming from the ventilated room and the adsorbent is regenerated by the reject stream of the membrane unit.
