Abstract

This study deals with $de-SO_X$ and $de-NO_X$ process of a wet scrubber for small size ship engines. The experiment was conducted according to the E3 mode of the $NO_X$ technical code. In order to discharge the sulfur containing flue gas, ditertiarybutyldusulfide was added to the diesel fuel to increase the sulfur content. NO gas, which occupies most of the nitrogen oxides in the exhaust gas, was oxidized into $NO_2$ and absorbed by a wet scrubber. The developed equipment of this work achieved 100% of removal efficiency for highly soluble $SO_2$ gas in an aqueous solution.

본 연구는 중 소형 선박의 배가스에 포함되어 있는 황산화물 및 질소산화물을 처리하기 위한 습식 스크러버의 처리효율에 관한 내용이다. 실험은 질소산화물 기술문서($NO_X$ Technical Code)의 E3 모드에 준해서 진행하였다. 엔진에서 황산화물을 배출하기 위해서, 연료로 사용되는 경유에 ditertiarybutyldusulfide를 혼합하여 황 함유량을 높인 연료로 실험을 진행하였다. 배가스 내의 질소산화물의 대부분을 차지하는 NO가스는 $NO_2$로 산화시켜 습식 스크러버로 흡수하였으며, 황산화물인 $SO_2$는 세정액에 잘 흡수되어 100% 처리효율을 확인하였다.
