초록

저온 플라즈마 기술의 하나인 필스 코로나 방전을 이용한 질소산화물 제거기술에 대하여 살펴보았다. 운전전력 저감방법으로서 에틸렌이나 프로필렌과 같은 올레핀계 탄화수소 첨가제를 사용하였고, NO의 산화반응기구에 있어서 이들 탄화수소 첨가제의 역할을 고찰하였다. 프로필렌은 현재까지 가장 우수한 첨가제로 알려져 있는 에틸렌보다도 운전전력 저감에 있어서 훨씬 우수한 성능을 나타내었다. 고전압 방전에 의해 발생되는 다양한 종류의 성분 중에서 어떤 성분이 NO의 산화반응에 핵심적인 역할을 하는지 알아보기 위한 이론적 분석 및 실험을 통하여 오존이 NO의 산화에 있어 가장 중요한 성분임을 확인하였다. 이러한 결과는 펄스 코로나 방전에 의해서 뿐만 아니라 배가스에 오존을 주입하여도 질소산화물의 제거가 가능하다는 증거이며, 그 가능성은 실험을 통하여 입증되었다. 펄스발생회로의 구성요소 중 펄스형성축전기의 정전용량을 코로나 반응기 초기 정전용량의 5배로 하였을 때 최대의 에너지 이용효율이 얻어졌다.

The removal of nitric oxide by a pulsed corona discharge process was investigated. As an energy saving technique, the addition of hydrocarbons such as ethylene and propylene to flue gas was examined, and the scheme for the oxidation of NO facilitated by hydrocarbon was discussed. Compared to ethylene known asn the most powerful additive, propylene gave much better performance in the conversion of NO. From the theoretical and experimental analyses performed to find out active component dominantly affecting the oxidation of NO, ozone was found to play a major role in the oxidation of NO. It indicates that the removal of NO is also possible by injecting ozone to flue gas as well as by inducing corona discharge. The possibility for the removal of NO using ozone was experimentally proved. Maximum energy utilization efficiency for the removal of nitric oxide was obtained when the pulse-forming capacitance in the pulse voltage generator was five times larger than the geometirc capacitance of the corona reactor.
