PRESSURE VARIATION ADSORPTION TOWER AND ADSORPTION SEPARATION DEVICE AND PRESSURE VARIATION ADSORPTION SEPARATION

摘要

PROBLEM TO BE SOLVED: To provide a pressure variation adsorption tower capable of increasing a thermal efficiency in the same device structure as conventional one and capable of efficiently separating and recovering an objective component without necessitating a special device and the huge energy. ;SOLUTION: In the pressure variation adsorption tower of an adsorption separation device, the objective component in a mixed gas is separated and recovered by properly combining an adsorption stage, a blow down stage, a pressure equalization stage, a purge stage, a desorption stage and a pressurizing stage by using the adsorption tower 1 provided with a bed 2 filled with an adsorbent. In such a case, a filled layer 5 is formed by filling an inert filler in space parts at both ends of the bed 2 filled with the absorbent and provided in the adsorption tower 1.;COPYRIGHT: (C)1998,JPO
