Abstract

In Korea, not much interest has been paid yet to mercury among flue gas HAPs (Hazardous Air Pollutants), but mercury is expected to become a major problem in the near future. The present paper investigates the current state of mercury emission and control technologies. Interest of the U.S. and European countries in the area of air pollution has been recently directed to mercury emitted from power plants. There are largely two mercury removal technologies applied to power plants. One is removing mercury by oxidizing elemental mercury in WFGD (Wet Flue Gas Desulfurization), and the other is spraying an adsorbent such as activated carbon or other novel sorbents (low-cost sorbents). Developed country is requiring that all power plants be equipped with mercury control facilities by 2007. This paper aims at contributing to the establishment of future strategies in response to the problem.

국내의 HAPs(Hazardous Air Pollutants)중 수은은 아직까지 관심의 대상이 아니지만 머지않아 문제가 될 것으로 예측된다. 본 논문에서는 현재 국내외의 배가스 수은 배출현황과 처리기술에 대해 요약하였다. 미국을 중심으로 구미 각국에서는 대기분야의 연구개발이 수은에 집중되고 있다. 수은 제어 프로그램은 크게 두 가지로 방향을 잡고 있다. 하나는 기존의 WFGD(Wet Flue Gas Desulfurization)를 이용하여 수은을 산화시켜 제거하는 방법이며 다른 하나는 수은 제거효율이 높은 활성탄 또는 다른 novel sorbent (low-cost sorbent)를 사용하는 방법이다. 선진국에서는 2007년에 발전소 수은 제거설비 설치가 의무화 될 것이다. 본 논문에서 제공하는 자료는 국내에서 발전소 수은 규제가 시작될 때 효과적으로 적용될 수 있을 것이다.
