Abstract: 본 발명은 화력발전소 및 산업시설에서 배출되는 배가스 중의 황산화물을 제거하는 방법을 제공하기 위한 것이다.
종래의 강제 산화방식의 습식 석회석-석고법 배연 탈황 공정에 있어서 탈황효율을 향상시키기 위해서는 슬러리의 pH를 증가시키거나, 흡수탑의 종류에 따라 기-액 접촉비 또는 △P를 증가시켜야 하나 슬러리의 pH를 증가시킬 경우 탈황효율은 증가 하나 석회석 이용률과 부산석고의 순도가 낮아지며 기-액 접촉비 또는 △P를 증가시킬 경우 전력소모량 증가에 따른 운전비용이 증가하므로 효용성이 낮다.
본 발명은 상기의 문제점을 해결하고 탈황설비에서 흡수제로 사용되는 석회석 이용률 및 부산물인 석고 순도 향상과 동일한 운전조건에서 탈황효율을 최대화 할 수 있도록 탈황설비 흡수탑에 유기산 첨가제의 일종인 DBA를 주입하고, 탈황폐수중의 COD 증가 문제 등 폐수 성상 변화에 따른 탈황 폐수 처리 방법을 증발처리법으로 구성하여 탈황폐수를 효율적으로 처리할 수 있도록 하였다.-
