GAS PURIFYING APPARATUS AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gas purifying apparatus and a method for successfully regenerating an adsorbent by suppressing condensation of chemical substances on a surface of the adsorbent lowering by the gravity and stabilizing the fluidization of the adsorbent.

SOLUTION: The gas purifying apparatus 1 includes an adsorbing part A bringing gas G containing chemical substances into contact with the adsorbent K to adsorb the chemical substances into the adsorbent K, a separation part D separating the chemical substances from the adsorbent K by bringing non-condensable gas Ga into countercurrent contact with the adsorbent K lowering through the adsorbing part A while forming a moving bed, wherein an adsorbent body temperature control part C is provided between the adsorbing part A and separation part D, for keeping the lowering adsorbent K at a temperature of from the dew point of the non-condensable gas Ga containing the chemical substances having passed through the separation part D to dew point +50°C.
