중소형 선박의 SOX/NOX 동시제거를 위한 습식세정시스템

Simultaneous removal of SOX and NOX by wet scrubber at small and medium craft

In recent years, researchers have put a considerable effort to decrease the emission of harmful gaseous pollutants to the atmosphere. In order to remove simultaneously SO2 and NOX from the flue gas of small and medium-sized ship, we designed minimal wet scrubber inside a compact multistage modular system. In this study we proceed experiment of elemental technology at each stage of the scrubber. The each stage is oxidation of NO which is the main component of NOX, and removal of SO2, respectively. NaClO2 was used to oxidize NO gas, and NaOH was used to remove SO2 gas. The maximum NO conversion efficiency and the SO2 removal efficiency are both indicate 100%.
