Title:
GAS TREATMENT METHOD AND GAS TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/080266
Kind Code:
A1
Abstract:
According to the present invention, a gas treatment method comprises the steps of: supplying, to a carbon dioxide collector, a mixture gas in which a gas to be treated and ammonia gas are mixed, and cooling the mixture gas so as to generate carbon dioxide-captured ammonium carbonate, thereby separating the carbon dioxide from the gas to be treated; and capturing hydrogen sulfide from the gas to be treated, which was discharged from the carbon dioxide collector after carbon dioxide was separated therefrom, separating the hydrogen sulfide and ammonia, and generating sodium hydrogen sulfide. Therefore, according to an embodiment of the present invention, a gas treatment apparatus can improve a hydrogen sulfide capture rate by selectively capturing carbon dioxide before capturing hydrogen sulfide, and thus the quality of sodium hydrogen sulfide to be produced can be improved.
