다단계 연소버너는 유해하고 난연성 물질인 염화화합물을 연소하기 위해 연소의 3T 조건(난류혼합, 높고 균일한 온도, 잔류시간)을 향상시키기 위해 개발되었다. 버너는 3부분 (기화부분, 첫 번째 연소부분, 두 번째 연소부분)으로 구성되어있으며, 액체 연료는 기화부분에서 빠르게 기화되고, 첫 번째 연소영역에서 기화된 연료와 공기가 연소되며 2차 연소영역에서 재 연소된다. 버너 연소 효율 실험은 염소화합물 연소시 화염 후류에서 발생하는 중간 생성물양으로 측정하였다. PCP는 상온에서 고체 상태이며 경유에 녹였으며, 그 농도는 경유량으로 1.0%-1.6%사이로 하였다. 가스 및 그을음은 버너 후류가스에서 포집하였으며, GC로 분석하였다. 중요결과로 그을음은 거의 모든 실험조건에서 검출되지 않았지만, 약간의 위해성 중간 생성물은 검출되었다. PCP농도 1.0%이하에서는 중간 생성물의 농도가 낮았지만, PCP농도가 증가 할수록 중간생성물의 농도가 증가 하였다. 그중 중요한 중간 생성물로는 클로로벤젠이었다. A multistage burning burner was developed and designed to improve 3 T`s conditions, turbulent mixing, high and homogeneous temperature, and residence time to incinerate spent chlorine contaminated solvents, which were known as dangerous and difficult combustible compounds. The burner consisted of 3 main parts, evaporating unit, first burning zone, second burning zone. Liquid fuel was able to be fast vaporized in the vaporizing unit, and the vaporized fuel and air rapidly mixed and incinerated in the first and after second burning zone in the burner. The burner was tested and examined in terms of the efficiency of combustion and the Amount of emitted hazardous intermediate species from the flames by burning the Chlorinated compound. PCP(Pentachlorophenol), which is solid at environmental condition, Was selected as a chlorinated compound and dissolved in the diesel fuel. The concentration Range of PCP in the diesel fuel was 1.0%-1.6% as of diesel fuel volume. Gas and soot Samples collected at the downstream of the burner were analyzed with a gas Chromatography. Soot sample was extracted with C<sub>2</sub>H<sub>2</sub>Cl<sub>2</sub> before injucted into the GC. As of important results, the amount of soot was almost negligible or non detectable over All experimental conditions, but some of hazardous intermediate compounds were detected. The concentrations of the intermediates were very low at 1.0% of PCP, however they Increased as PCP was loaded more in the flame. One of important intermediates was chlorobenzene.

축열식산화장치는 미국사의 제작품으로, S사에서 설치했으며 현장에서의 문제점을 줄이고, 열회수율 증가를 위해 성능보증조건에서 실험을 하였다. 화학공정의 배출원에서 방출되는 가스는 유입송풍기로 축열식산화장치에 유입시켰으며 보조연료로 경유를 사용하였다. 가스샘플은 설계된 최적운전조건에서 배출원의 말단부와 축열식산화장치의 스택에서 채취하였다. 방출가스의 총탄소는 가스를 연속적으로 배출시키면서 탄화수소측정기로 분석하였으며, 방출가스 중 휘발성유기화합물은 Carbo Trap으로 채취후 가스크로마토그라피로 분석하였다. 배출가스 중 주된 휘발성유기화합물은 스틸렌모노머이며, 파괴효율은 90%이상 이었다. 포펫밸브의 전환주기를 240초에서 150초로 조정하였고, 연소기의 운전온도를 927℃에서 820℃로 변환하여 열회수율이 90%에서 93%로 개선되었고, 총탄소의 파괴효율도 90%에서 97%로 증가하였다. 더욱이 축열능력을 증대시키기 위해 축열재(세라믹 새들)를 추가 투입하여 95%의 열회수율을 얻었다. Regenerative Thermal Oxidizer(RTO), which was manufactured by America`s Co and Built by S Co., was tested to reduce on-site problems and to improve heat recovery efficiency, the performance guarantee figure of the RTO. The fume gases from the chemical processes, emission sources, were introduced to the RTO by induced fans, and a diesel fuel was used as an auxiliary fuel. Gas samples were collected at the downstream of the emission sources and the stack of The RTO under the designed optimal operating condition. For TOC(Total Carbon) the exhaust gas was withdrawn continuously and analyzed with a hydrocarbon vapor meter, and the exhaust gas was also collected on the Carbo Trap(type B) tube and analyzed with a gas chromatography for VOCs. The main VOCs among the fume gases were Styrene Monomer, and their EREs were Obtained up to 90%. By coordinating the conversion cycle of poppet valve from 240 Seconds to 150 seconds and changing the operation temperature of the combustor from 92 7℃ to 820℃, the heat recovery efficiency was improved from about 90% to 93% and ERE Of the TOCs was increased from 90% to 97%. Furthermore 95% efficiency of heat recovery was obtained by inputting an additional regenerative thermal media(Ceramic saddle) to increase the thermal capacity.

The road map to reduce green house gas in the mid and long term is required to improve international competitiveness and minimize economic loss by government regulations. Many companies in the Gunsan2 National Industrial Complex should enforce the target management system of energy and green house gas and strengthen its standard in the future according to low-carbon green growth acts. In this study, the reduction of green house gas emissions was investigated through the improvement of operation methods, facilities, heat recovery of exhaust,energy conversion, and heating reactor. If this green house gas reduction plan is applied to major companies in the Gunsan2 National Industrial Complex, a total of 68,942 tCO2eq can be reduced in 2015.

The purpose of this study is to measure composite odor and designated odor in 33 emission sources at 11business sites generating odor in the Wanju Industrial Complex, examine characteristics and problems of majored or substances for each odor emission source, and establish an optimal means to reduce odor according to characteristics of the site. As a result of assessing odor emission characteristics in this study, major odor substances were found to be ethyl benzene, toluene and xylene for automobile parts manufacturing business, styrene, ethylbenzene and toluene for synthetic resin and other plastic materials manufacturing business, and styrene, trimethylbenzene, ethylbenzene, nitric acid and formic acid for other manufacturing businesses. Apartments located closest in the northern and southern boundaries of the industrial complex were predicted to be surrounding regions receiving greatest effect of odor emitted by business sites, and increase in apartment floor was predicted to show greater effect of odor.

It is necessary to evaluate the greenhouse gases (GHGs) reduction policy by central and regional governments to set up the suitable GHG emissions measures. Quantitative, qualitative and synthetic methods have been adopted by previous researches to estimate GHG reduction policy. However, these methods mostly focused on the results of the reduction policy, rather than understanding and fixing the integrated structures of GHG emissions. In this research, System Dynamics(SD) was applied to 1 million green homes program, self-carfree-day system and carbon point program. The results showed that SD analyses could be appliable for the estimation of GHG reduction policy by developing the feedback loops and dynamic simulation model. SD can be consider as a supplementary tool to estimate the GHG reduction policies through the recognition of the structure in complex real system.
