FIELD: technological processes.
SUBSTANCE: invention relates to separation of gas mixes by short-cycle unheated adsorption. Gas mix flow is subjected to compression in compressor and forced cyclically through adsorbent layer in two parallel jointed adsorption columns wherein pressure increase and decrease conditions are sequentially maintained. Said conditions are maintenance using synchronous switching of inlet and outlet valves. In the proposed vertical adsorber with a variable internal volume, a fixed partition with a movable valve in the shape of a truncated cone is installed. In the desorption mode, the load on the pump is reduced by lowering the internal volume of the adsorption column.
EFFECT: invention provides increase in the efficiency of the adsorbent regeneration process in the desorption mode and decrease in energy costs.
