This study estimated the emission characteristics of odorous volatiles organic compounds (VOCs) from major 7 emission facilities by industrial classification in Yeosu petrochemical industrial complex. This study investigated terminal emission facilities (Inlet and outlet) in the industrial plant area, the plant boundary area and Samil-dong which has many civil appeal for an offensive odor to grasp VOCs concentration in ambient air of the plant boundary area and civil appeal area from May, 2002 to December, 2004, besides. VOCs were sampled 6 L using silicocan canisters and toluene, xylene and styrene which are known as odorous VOCs were analyzed by cryogenic preconcentration system and GC/MS. The removal efficiency of emission facilities in the industrial plant area for odor showed 96.5% of wet scrubber, 89.5% of RTO and 86.0% of RCO. The concentration of odorous VOCs at the plant limits area in 2003 were higher than 2002. The reason was guessed that toluene of high concentration emitted from terminal emission facilities in the industrial plant area influenced on ambient air at the plant boundary area. The concentration of odorous VOCs in ambient air at Samil-dong were decreasing from 1995 to 2001, but the concentration of toluene sharply increased from 2002. The reason was presumed that VOCs emission increased due to expansion of Yeosu petrochemical industrial complex and removal efficiency of terminal emission facilities dropped due to outworn equipments for VOCs prevent.

The aim of this study was to investigate the legally-designated malodorous compounds at the plant boundary areas of 5 plants expected to emit high odor intensities, as well as! complaint area at the Yeosu petrochemical industrial complex in Korea. The sampling was carried out during spring and summer of 2003 and 2006. The concentrations of ammonia, sulfur compounds (hydrogen sulfide, methyl mercaptan, and dimethyl sulfide) and aldehydes (acetaldehyde and propionaldehyde) emitted during 2006 were higher than those emitted during 2003, and the concentrations emitted during summer were higher than those emitted during spring at the plant boundary areas. It was thought that the concentrations of odorants in the complaint area had been directly influenced by the concentrations of odorants in the plant boundary areas as they showed similar patterns of concentration variations. While the concentration of TMA during 2006 was lower than during 2003 at the all sampling sites, the concentration of styrene during 2006 was higher than during 2003 at the all sampling sites. The sites showed high concentrationsof odorous compounds at the plant boundary area of the related chemical and petrochemical refinery plants.

-14, was selected todevelop a VOCs’ source prole matrix of the Yeosu Petrochemical Complex and to test its collinearity by singularvalue decomposition(SVD) technique. The VOCs collected in canisters were sampled from 12 different sourcessuch as 8 direct emission sources (refinery, painting, wastewater treatment plant, incinerator, petrochemicalart activity, vehicle emission, and asphalt paving activity) in this study area, and then those samples were analyzedby GC/MS. Initially the resulting raw data for each profile were scaled and normalized through several datatreatment steps, and then specic VOCs showing major weight fractions were intensively reviewed and comparedcollinearity by SVD technique. The study nally could provide a proper VOCs’ source profile in the study area,which can give opportunities to apply various receptor models properly including chemical mass balance(CMB).

The concentrations of volatile organic compounds (VOCs) in the ambient air were measured at three sites (Samil-dong, SRO and EFMC) in Yeosu industrial complex during September 2000 to August 2001. Air samples were collected for 24 hours in Silicocan canister (6ℓ) with constant flow samplers every 6 days and analyzed using a cryogenic preconcentration system and a GC/MS. At each site, we identified 35 species known as on both the carcinogenic and mutagenicity by the EPA US (TO-14 manual). No relationship was found between VOCs concentration at three sampling points. Furthermore, the result shows that there appears to be a variety distribution of the concentration. BTX, vinyl chloride and high concentrations of I, 2-dichloroethane were observed at the sampling sites. Especially, high concentration of toxic VOCs, such as vinyl chloride, chloroform, I, 2-dichloroethane and benzene were shown at environmental facilities management cooperation (EMFC) site. They seem to be emitted from the facility of wastewater treatment in Yeosu industrial complex. It was difficult to tell the seasonal variation of total VOCs concentration. Nevertheless, the concentration in winter was typically higher than in summer. The concentrations of toxic VOCs contents in Yeosu industrial complex were generally lower than those in Ulsan complex, although those were similar or less than in Seoul and Daegu. Whereas, toluene and styrene emitted from Yeosu industrial complex were higher than those of Edmonton industrial complex in Canada. Especially, toluene was third times higher than those observed from Texas, USA.

VOCs 시료는 silicocan canister 6 L로 채취하였으며, 저온농축장치(cryogenic preconcentration system)와 GC/MS를 이용하여 분석하였으며, 조사항목은 악취성 VOC로 알려진 3개 항목(toluene, xylene, styrene)을 분석하였다. 연구결과는 다음과 같으며, 사업장내 배출시설의 악취 제거효율(removal efficiency)은 흡수탑 (96.5%) > RTO (89.5%) > RCO (86.0%) 순으로 우수한 것으로 나타났다. 사업장 부지경계지점은 2002년에 비해 2003년의 악취성 VOC 농도가 상승한 것으로 조사되었다. 이는 사업장내 최종 배출시설 자체에서 toluene 물질이 높은 농도로 배출되어 사업장 부지경계지역의 대기 중 농도에 영향을 미친 것으로 생각된다. 민원지역인 삼일동 지점의 대기 중 악취성 VOC 농도는 1995년부터 2001년까지 점차 감소하다가 특히 toluene 성분은 2002년부터 다시 급격히 증가하는 경향을 보였다. 이는 여수산단지역 확장으로 인한 사업장내 VOC 물질 배출 증가와 10여년 전에 설치된 VOC 방지시설의 노후로 인한 방지효율 저감에 의한 영향으로 생각된다.

The purposes of this study were to characterize the local levels of VOCs (volatile organic compounds), to develop source profiles of VOCs, and to quantify the source contribution of VOCs using the CMB (chemical mass balance) model. The concentration of VOCs had been measured every 6-day duration in the SRO monitoring site in the Yeosu Petrochemical Industrial Complex from September 2000 to August 2002. The total of 35 target VOCs, which were included in the TO-14 designated from the U.S. EPA, was selected to be monitored in the study area. During a 24-h period, the ambient VOCs were sampled by using canisters placing about 10~15 m above the ground level. The collected canisters were then analyzed by a GC-MS in the laboratory. Aside from ambient sampling at the SRO site, the VOCs had been intensively and massively measured from 8 direct sources and 4 general sources in the study area. The results obtained in the study were as follows; first, the annual mean concentrations of the target VOCs were widely distributed regardless of monitoring sites in the Yeosu Petrochemical Industrial Complex. In particular, the concentrations of BTX (Benzene, Toluene, Xylene), vinyl chloride were higher than other target compounds. Second, based on these source sample data, source profiles for VOCs were developed to apply a receptor model, the CMB model. Third, the results of source apportionment study for the VOCs in the SRO Site were as follows; The source of petrochemical plant was apportioned by 31.3% in terms of VOCs mass. The site was also affected by 16.7% from wastewater treatment plant, 14.0% from iron mills, 8.4% from refineries, 4.4% from oil storage, 3.8% from automobiles, 2.3% from fertilizer, 2.3% from painting, 2.2% from waste incinerator, 0.6% from graphic art, and 0.4% from gasoline vapor sources.
