Non-thermal Plasma and $NH_3$ SCR Hybrid Process for Treating Diesel Engine Exhaust

저온 플라즈마와 $NH_3$ SCR 복합공정을 이용한 디젤엔진 배기가스의 NOx 저감 기술

A hybrid De- NOx technique of non-thermal plasma and $NH_3$ SCR process has been investigated to remove NOx from 300 hp marine engine exhaust under the low temperature conditions, i.e. $100-200^{\circ}C$. Fundamental investigation with Diesel-like simulant gas was also conducted. The performance of the present technique has been demonstrated by treating real diesel exhaust gases, in which high contents of soot, water vapor, $SO_2$, NOx, and unburned HC are included. Detailed engineering data for evaluating the feasibility of the technique are provided in the present investigation.
