Abstract

과량의 수증기와 암모니아가 포함된 황화합물 함유 혼합가스로부터 황화합물을 제거하는 방법이 제공된다.A method is provided for removing sulfur compounds from a mixture of sulfur compounds containing excess water and ammonia.

본 발명에 따르면 과량의 수증기 및 암모니아에 포함된 소량의 황화수소 및 이산화탄소 등 혼합가스를 고온 산화반응기 내에서 산화시켜 암모니아는 질소와 물로 황화수소는 이산화황으로 완전 산화한 다음, 촉매 환원 반응기 내에서 이산화황을 황화수소로 전환시키고 그 황화수소를 탈황 설비 공정 전단으로 보내 제거하는 방법을 제공한다.According to the present invention, a small amount of hydrogen sulfide and carbon dioxide mixed with excess water vapor and ammonia are oxidized in a high temperature oxidation reactor to completely oxidize ammonia to nitrogen and water, hydrogen sulfide to sulfur dioxide, and then sulfur dioxide to hydrogen sulfide in a catalytic reduction reactor. And the hydrogen sulphide is sent to the front end of the desulfurization plant process for removal.

본 발명은 산화 반응기 조업이 용이하고 추가 연료장입 없이도 반응 온도를 유지할 수 있으며, 별도의 암모니아 처리장치 없이 암모니아를 제거할 수 있는 잇점을 지닌다.The present invention has the advantage of easy operation of the oxidation reactor, maintain the reaction temperature without additional fuel loading, and can remove ammonia without a separate ammonia treatment device.
