放電による非水溶性臭気物質の除去

This article describes the bench scale experiments (the flow rate of odor gas about 1 Nm³ /min) for removal of the water insoluble odor (ethyl mercaptan (EM) and dimethyl sulfide (DMS)) using corona discharge. The odor concentration was adjusted by the bubbling of the odors solutions diluted the excess ethanol into cooling container. The concentration of the odor was successfully controlled by the flow rate of bubbling gas (N₂) and it enabled a stable experiment for a long period of time. The decomposition of EM and DMS was accomplished by the corona discharge reactor consisted of four stainless wires and achieved over 50% conversion at electric power of 15W. Furthermore, the experimental results suggested that the most of EM directly was due to decomposition into corona plasma not oxidation of the ozone produced by corona discharge. But the decrease of DMS concentration combined of discharge decomposition and ozone oxidation
