Claims (6)
- 고로 슬래그 냉각수 중에 모노에탄올아민, 디에탄올아민, 트리에탄올아민, 디에텔렌트리아민의 에탄올아민을 통해 황화수소를 1차 제거하고, 아민용액을 미세분사하여 고로 슬래그 냉각 중에 발생하는 황화수소를 2차 제거하는 것을 특징으로 하는 아민류를 이용한 고로 슬래그 중의 황화수소 제거방법.
- 삭제
- 제1항에 있어서,황화수소를 1차 제거시 아민류의 농도는 10~200ppm으로 하여 황화수소를 저감하는 것을 특징으로 하는 아민류를 이용한 고로 슬래그 중의 황화수소 제거방법.
- 제1항에 있어서,황화수소를 2차 제거시 아민류의 농도는 10~200ppm, 분사량은 200~1000kg/min 으로 함을 특징으로 하는 아민류를 이용한 고로 슬래그 중의 황화수소 제거방법.
- 고로에서 발생된 슬래그를 교반조에서 처리하는 과정중에 발생되는 황화수소를 제거하는 제거장치에 있어서,상기 교반조의 배가스 유로에 설치되어, 황화수소의 2차 제거를 위해 아민용액을 미세분사하는 스프레이 노즐을 포함하여 이루어지는 것을 특징으로 하는 아민류를 이용한 고로 슬래그 중의 황화수소 제거장치.
- 제5항에 있어서,상기 교반조의 상기 스프레이 노즐의 하부에 설치되어, 황화수소의 2차 제거시 상기 스프레이 노즐을 통하여 미세분사된 아민용액이 황화수소가 포함된 수증기와 접촉하는 시간을 증대시키기 위한 다수의 홀이 천공되어있는 방해판을 더 포함하여 이루어지는 것을 특징으로 하는 아민류를 이용한 고로 슬래그 중의 황화수소 제거장치.
