Abstract

제철소에서 부산물로 발생하는 백운석 슬러지를 이용하여 배가스중에 함유한 SOx가스를 제거하는 방법이 제공된다. 백운석 슬러지를 NaOH등의 알카리 수용액으로 처리하여 이를 탈황제로 사용하면 종래의 탈황제보다 그 효과가 우수하다. 상기 방법대로 폐자원의 재활용 측면 뿐만 아니라 환경오염문제 측면에서도 유용하고 탈황효과도 우수하다.Provided is a method for removing SOx gas contained in flue gas using dolomite sludge generated as a by-product from an ironworks. When dolomite sludge is treated with an aqueous alkali solution such as NaOH and used as a desulfurization agent, the effect is superior to conventional desulfurization agents. As described above, it is useful not only in terms of recycling waste resources, but also in terms of environmental pollution, and has excellent desulfurization effects.
