Title (EN) GAS TREATMENT METHOD AND GAS TREATMENT APPARATUS
(FR) PROCÉDÉ DE TRAITEMENT DE GAZ ET APPAREIL DE TRAITEMENT DE GAZ
(KO) 가스 처리 방법 및 가스 처리 장치
Abstract: front page image
(EN)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.
(FR)Selon la présente invention, un procédé de traitement de gaz comprend les étapes consistant: à fournir, à un collecteur de dioxyde de carbone, un gaz de mélange dans lequel un gaz à traiter et un gaz ammoniac sont mélangés, et à refroidir le gaz de mélange de façon à générer du carbonate d'ammonium capturé par du dioxyde de carbone, ce qui permet de séparer le dioxyde de carbone du gaz à traiter; et à capturer le sulfure d'hydrogène à partir du gaz à traiter, qui a été évacué du collecteur de dioxyde de carbone après que le dioxyde de carbone a été séparé de celui-ci, à séparer le sulfure d'hydrogène et l'ammoniac, et à produire de l’hydrogénosulfure de sodium. Par conséquent, selon le mode de réalisation de la présente invention, un appareil de traitement de gaz peut permettre d'améliorer le taux de capture de sulfure d'hydrogène par capture sélective de dioxyde de carbone avant la capture de sulfure d'hydrogène, et, par conséquent, d'améliorer la qualité de l'hydrogénosulfure de sodium à produire.
(KO)본 발명에 따른 가스 처리 방법은 처리 가스와 암모니아 가스가 혼합된 혼합 가스를 이산화탄소 포집기로 공급하여, 혼합 가스를 냉각시켜 상기 이산화탄소가 포집된 탄산암모늄염을 생성함으로써, 상기 처리 가스로부터 상기 이산화탄소를 분리하는 과정 및 이산화탄소가 분리되어 상기 이산화탄소 포집기로부터 배출된 처리 가스로부터 황화수소를 포집하여, 상기 황화수소와 암모니아를 분리하고, 황화수소나트륨을 생성하는 과정을 포함한다. 따라서, 본 발명의 실시형태에 따른 가스 처리 장치는 황화수소 포집 전에 이산화탄소를 선택적으로 포집함으로써, 황화수소 포집율을 향상시킬 수 있으며, 이에 따라 생산되는 황화수소나트륨의 품질을 향상시킬 수 있다.
