Abstract

Environmental awareness is rising worldwide. however, cement manufacturing facilities use recycled resources to improve raw material and fuel substitution rates, contributing to environmental issues such as waste disposal. The emission of sulfur oxides (SOx), an air pollutant, has been regulated by limestone as raw material in cement manufacturing. However, the impact of increasing use of recycled resources on future facility processes and environmental changes is unclear. Therefore, the cement manufacturing facilities require desulfurization-related technologies and research. In this study, we investigated the applicability of desulfurization technology to cement manufacturing facilities and demonstrated various approaches to applying this technology using byproducts generated in cement manufacturing.

전 세계적으로 환경에 관한 관심이 높아짐에 따라 시멘트 제조 시설은 순환자원을 사용하여 원료 및 연료 대체율을 향상시켜 폐기물처리와 같은 환경문제에 기여하고 있다. 대기오염물질 중 하나인 황산화물(SOx)은 석회석을 원료로 사용하는 시멘트 제조 특성상 배출관리가 잘 이루어지고 있지만, 순환자원 사용 증대에 따른 추후 설비 공정 및 환경 변화가 어떻게 변화될지는 미지수이다. 이에 따라 시멘트 제조 시설도 탈황 관련 기술 및 연구가 필요할 것으로 판단된다. 따라서 본 연구에서는 시멘트 제조 시설에서의 탈황기술 적용 가능성 조사 및 시멘트 제조 공정에서 발생되는 부산물을 활용한 탈황기술 적용 방안을 모색하였다.
