        This study was conducted to find an odor reducible solution in Hwayang agricultural industrial complex. Civilcomplaints have lasted because of odor caused by recycled plastic producers. In order to understand the emissioncharacteristic and concentration of key odor components, we investigated the complex odor and 17 odorcompounds at 3 sites of five chemical facilities from march to october 2013. The results of complex odor showed8~12 at a boundary of 5 facilities. The results of complex odor showed 6694, 3000, 1442 at an emission (stack)of 3 facilities, which exceeded the emission standard. The highest compound and its concentration of each sitewas different because each facility has different processes and use different raw materials. We suggested thesuitable prevention facility for each company to reduce odor. We analyzed the odor contribution with the emission(stack) point of S, I, B and the inside point of W, J. S plant was Acetaldehyde (45%), I plant was Trimethylamine(32%), B plant was Styrene (35%), W plant was Hydrogen sulfide (42%), J plant was Hydrogen sulfide(41%).An objective of study is odor management area and will apply odor strict emission standards. A suitable preventionfacility should be operated efficiently based on survey data to reduce odor.

        This study was conducted to evaluate the emission characteristics of air pollutants from incineration facilities in Jeollanam-do. We selected 8 incineration facilities depend on type and the 19 items such as dust etc. were measured at the measurement hole for emission gas from air contamination control units. The range of emission concentrations for dust was 2.8 ~ 20.9 mg/Sm3 less than permissible air discharge standards. The results of 10 gaseous contaminants such as SOx was less than permissible air discharge standards. The range of emission concentrations for NOx was 13.4 ~ 120.0 ppm, less than permissible air discharge standards. As G facility was 112.4 ppm, 120.0 ppm, it exceeded emission standard (100 ppm) twice. The range of emission concentrations for HCl was ND ~ 85.300 ppm, B Facilitiy exceeded emission standard (20 ppm) as 85.300 ppm. The range of emission concentrations for NH3 was ND ~ 76.333 ppm, A, D, H Facility exceeded emission standard (30 ppm). The concentration of each facility was 42.416 ppm, 62.930 ppm, 76.333 ppm. The results of heavy metals (5 items) showed within emission standards. G facility is operating in condition that input of urea is 100 L/day. If input of urea were changed to 50 ~ 75 L/day, the operating cost of air pollution prevention facility can be reduced by 25% ~ 50%. In this study, the correlation between urea input and nitrogen oxides was statistically significant, but the correlation between urea input and ammonia showed insignificantly. Our research attempts to evaluate the emission characteristics of air pollutants from incineration facilities and to institute a reduction plan, an effective management of incinerators.
