Abstract

본 발명은 암모니아 흡수탑에 물과 코크스 가스를 공급하여 암모니아 황화수소를 흡수시키고 암모니아 흡수탑의 최상부에 설치된 산화제 공급장치로부터 산화제로서 과산화수소를 투입하여 황화수소를 산화시킨 후 상기 암모니아 및 황화수소가 흡수된 조안수를 증류탑에 공급하여 암모니아를 분해하고 암모니아가 탈기된 탈안수는 암모니아 흡수탑으로 순환시키는 것으로 구성된 코크스가스 중의 암모니아 및 황화수소의 제거방법에 관한 것이다.The present invention absorbs hydrogen ammonia sulfide by supplying water and coke gas to the ammonia absorption tower, and adds hydrogen peroxide as an oxidant from an oxidant supply device installed at the top of the ammonia absorption tower to oxidize hydrogen sulfide, and then the ammonia and hydrogen sulfide are absorbed The present invention relates to a method for removing ammonia and hydrogen sulfide in coke gas, which is supplied to a distillation column to decompose ammonia and deammonia degassed with ammonia.
