반월ㆍ시화산업단지의 화학공장을 대상으로 한 악취물질 배출특성에 관한 연구


We investigated dilution ratio values of the threshold limit (DRVTL) and 12 odorous compounds from a number of emission points (stack and process) and boundary areas of 10 chemical industries in the Ban-Woll and Shi-Wha Industrial Complex in Gyeonggi Province. The results of our study suggest that differences in odor emission concentrations are caused by such as factors as : suitability and operational conditions of prevention equipment, suitability hood of process and exhaust ventilation system, differences of raw materials of chemical industry. It was found that trimethylamine and hydrogen sulfide recorded the highest contribution from two types of emission points (stack and process), respectively. Show some actual concentration values here, hydrogen sulfide recorded its maximum values from leather industry, while trimethylamine for hexamine production industry. On the other hand, the results of dimethyl sulfide, dimethyl disulfide and methyl mercaptan were not useful, as their concentrations were not significantly high enough to judge from such respect. In the view-point of dilution ratio values of the threshold limit, the average emission ratio of stack and process from 10 chemical industries was 57, 43%, respectively. Therefore, it is important that the odor emission value from process and stack have to minimize and regulate for management of industrial odor.
