Zusammenfassung:The present invention relates to a method and an apparatus for purifying discharge gas containing a sulfur oxide generated from an internal combustion engine using a multi-stage adsorption process, which can purify contaminants from a flow of the discharge gas of the internal combustion engine operated by fuel containing sulfur, in particular the internal combustion engine for a ship operated by heavy oil. According to the present invention, the method allows the flow of the discharge gas to come in contact with a solid adsorbent of an adsorbing device in a first step of allowing the acid contaminants containing sulfur dioxide and sulfur trioxide to be coupled and allows the flow of the discharge gas to continuously pass through a second step of the finely purified adsorbing device, wherein the adsorbent of the second step is used as the adsorbent in the first step. 내연기관으로부터 발생한 황 산화물을 포함한 배출 가스를 다단 흡수 공정을 이용하여 정화하기 위한 방법 및 장치. 본 발명은, 황을 포함한 연료에 의해 작동되는 내연기관 특히, 중유(heavy oil)에 의해 작동하는 선박용 내연기관의 배출 가스 유동으로부터 오염물을 정화하기 위한 방법 및 장치에 관한 것이다. 본 발명에 의하면, 특히 이산화황 및 삼산화황을 포함한 산성 오염물이 결합되는 제1단계에서 배출 가스 유동이 흡착기의 고형 흡착제와 접촉하여 계속해서 상기 배출 가스 유동은 미세하게 정화되는 흡착기의 제2단계를 통과하고, 상기 제2단계의 흡착제가 상기 제1단계에서 흡착제로서 이용된다.
