REGENERATION METHOD FOR ACID-GAS ADSORPTION DEVICE, MANUFACTURING METHOD FOR ACID-GAS ADSORPTION DEVICE, AND OPERATING METHOD FOR ACID-GAS ADSORPTION DEVICE

WIPO Patent Application WO/2024/004928

A1

Provided are: a regeneration method for an acid-gas adsorption device and an operating method for an acid-gas adsorption device, the methods being capable of smoothly recovering the acid-gas recovery performance and reducing running costs; and a manufacturing method for an acid-gas adsorption device, the method being capable of manufacturing an acid-gas adsorption device achieving superior acid-gas recovery performance. A regeneration method for an acid-gas adsorption device according to an embodiment of the present invention includes: a step for causing an acid gas to be adsorbed by an acid-gas adsorbent by supplying the acid gas to an acid-gas adsorption device so as to come into contact with an acid-gas adsorbing layer; a step for causing the acid gas to be desorbed from the acid-gas adsorbent; and a step for supplying the acid-gas adsorbent to the acid-gas adsorbing layer of the acid-gas adsorption device, which has been subjected to the step for causing the acid gas to be adsorbed and the step for causing the acid gas to be desorbed, so that the acid-gas adsorbent is attached to the acid-gas adsorbing layer.
