APPARATUS OF ABSORBING SEPARATE

摘要

A mixed gas is inducted into a abosrption tower(21,22), which is filled up with absorbent. The absorbent portion of the mixed gas adheres to the absorbent of the tower and the other gas extrudes the tower. The non-absorbent gas, which extrudes the tower, is delivered to a adiabatic expansion engine (33) to recover the pressure energy of the gas. Heat exchange is occured between the non-absorbent gas extruded the expansion engine and the mixed gas before this mixed gas is compressed. This heat exchange decreases the mixed gas temperature.
