Title:
ACID GAS COLLECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/048566
Kind Code:
A1
Abstract:
Provided is an acid gas collection method with which it is possible to reduce oxidation degradation and volatilization-caused abrasion of an acid gas adsorbing material. The acid gas collection method according to an embodiment of the present invention sequentially includes an absorbing step, a desorbing step, and a cooling step. In the absorbing step, a gas to be processed containing an acid gas is supplied to an acid gas absorbing device including an acid gas adsorbing material, and the acid gas is absorbed by the acid gas adsorbing material. In the desorbing step, the acid gas absorbing device is heated, and the acid gas is desorbed from the acid gas adsorbing material. In the cooling step, the acid gas absorbing device is cooled by a cooling medium with a temperature less than ambient temperature.
