<p>PURPOSE: To provide a method which can suppress waste of energy needed for desorption of a substance from an adsorption bed even if there exists fluctuation in concn. of a specified substance which an original gas contains, and its apparatus. CONSTITUTION: A gas processing apparatus is provided with an adsorption bed 1 which adsorbs a solvent in air, a blower 5 feeding a solvent-contg. air to the adsorption bed 1 and feeding a part of the air from which the solvent is adsorbed to the adsorption bed 1 so as to use the part of the air for desorption of the solvent from the adsorption bed 1, and a heater 6 for heating the air used for desorption of the solvent. In addition, a temp. measuring sensor 7 for measuring the temp. of the air which desorbs the solvent from the adsorption bed 1 and a temp. controlling device 8 for controlling a heater 6 so as to make the temp. a specified fixed value based on a signal from the temp. measuring sensor 7.</p> |
