FIELD: separation equipment.
SUBSTANCE: group of inventions relates to separation of a gas mixture flow by adsorption at a variable temperature. The method of operating the adsorption plant at variable temperature includes operation of three adsorption modules in the adsorption phase, in the feeding phase, in the regeneration phase, in the washing phase, and then in the cooling phase. A distinctive feature of the method is that in the same period of time one of the adsorption modules operates in the adsorption phase, one of the adsorption modules operates in the washing phase, and one of the adsorption modules operates in the feeding phase, and during the first working periods, part of the second gas mixture is fed into the adsorption module operating in the washing phase as the third gas mixture or part of the third gas mixture, and the fourth gas mixture or part of the fourth gas mixture is supplied to the adsorption module operating in the feeding phase. A variable temperature adsorption unit is also disclosed.
EFFECT: efficient use of the adsorbent and increase the yield of the target component.
