Abstract
국문요지 본 연구는 점착 및 접착테이프 생산사업장에 설치된 축열식산화장치를 중심으로 총탄화수소의 제거효율과 에너지 절감효과를 분석 ‧
제시함으로써 향후 동종 시설의 대기오염물질 배출억제를 위한 배출허용기준 설정 등의 환경관리대책마련 및 적절한 대기오염방지시설 설계의 기초자료를 제공하기 위한 목적으로 수행하였다. 점착 및 접착테이프 생산 공정과 대기오염방지시설인 RTO의 기초조사를 위해 배출가스의 특성 및 RTO의 설치현황을 조사하였으며, 연소실 온도변화에 따른 THC의 제거효율을 조사하였다. 또한, 세라믹 축열재의 축열 효율과 버너 가동율, 연료사용량 조사를 통해 RTO의 에너지 절감효과를 조사하였다. 점착 및 접착테이프 생산 공정에서 배출되는 가스의 조성은 생산되는 제품에 따라 원료투입량에 대한 유기용제 구성성분의 비율에 큰 차이가 있었으며, 3사 모두 Ethyl Acetate와 Toluene의 구성성분 비율이 높은 것으로 조사되었다. 또한, RTO의 공급실적은 소각방식의 방지시설 중에서 THC의 제거효율이 가장 우수한 것으로 알려진 RTO가 89.5%로 가장 높았고, RTO의 THC 제거 효율은 연소실 온도가 증가함에 따라 증가되는 것을 확인할 수 있었다. RTO의 에너지절감효과를 알아보기 위해 수행한 연소실 운전온도 변화에 따른 세라믹 축열재의 축열 효율을 분석한 결과, T사의 경우 연소실 온도가 상승할수록 95.2 ~ 96.0%의 범위에서 등락을 함에 따라 연소실 온도에 따른 축열 효율 변화특성을 보이지 않았으나, I사의 경우 연소실 온도가 650℃에서 850℃로 증가할수록 축열 효율이 93.7%에서 95.1%로 소폭 증가하는 경향을 보였다. 일반적인 RTO의 연소실 운전온도인 800℃에서의 세라믹 축열재의 축열 효율이 95%내외로 기존 연구와 비슷한 결과를 보임으로써 직접연소장치에서 사용되는 열교환기의 효율이 60 ~ 75%인 점을 비교하였을 때 세라믹 축열재를 이용한 RTO는 보조연료 사용량을 최소화 할 수 있으므로 에너지 절감효과가 매우 크다는 것을 확인할 수 있었다. 또한, RTO의 버너 가동율은 연소실온도와 에너지로 전환될 수 있는 유기용제의 농도, 세라믹 축열재의 축열 효율 등의 복합적인 영향을 받는 것으로 보여 졌다. RTO를 설치하기 전과 후의 에너지 사용량의 비교가 가능한 S사를 대상으로 연료사용량에 따른 에너지 절감 효과를 분석한 결과 연간 466,768,800원의 연료를 절감할 수 있을 것으로 나타났다. 본 연구의 결과는 점착 및 접착테이프 생산 공정의 대기오염물질 배출억제를 위한 배출허용기준 설정 등의 환경관리대책마련 및 적절한 대기오염방지시설 설계에 도움이 될 것을 기대하며, 향후 후속연구로써 점착 및 접착테이프 생산 공정에서 배출되는 배출가스의 대기 질에 대한 기여도와 경제적이고 효율적인 대기오염방지시설별 제거효율에 대한 연구와 기술개발이 필요할 것으로 사료된다. | Abstract A Study on the Removal Efficiency and Energy Saving Effects of Total Hydrocarbon(THC) using Regenerative Thermal Oxidizer(RTO) in the Pressure Sensitive Adhesive Tape Manufacturing Process Kim, Mi Young Depart. of Environmental Engineering The Graduate School of Engineering Hanyang University (Supervised by Professor Yoon Shin Kim, Dr. H. Sc., Ph. D.) This study was conducted to analyze and present the removal efficiency of THC(Total Hydrocarbon) and the effect of saving energy Based on the RTO(Regenerative Thermal Oxidizer) installed at the production process for pressure sensitive adhesive tape, with the goal of provide basic data of proper air pollution preventing facilities design and environmental management measures such as settling effluent quality standard for air polluting emission control of further same facilities. We looked at the characteristics of each discharged gas and the current state for the installation of RTO which is the facility for the prevention of air pollution throughout the basic investigation process. Also, we investigated the removal efficiency of THC according to the changes of temperature in the combustion chamber. Also, by investigating the removal efficiency of ceramic regenerative materials, the operating rate of burners, and the used amount of fuel, we investigated the energy saving effect of RTO. There was a big difference for the constitutive ratios of organic solvents regarding the input of materials for the formation of gases discharged in the process of manufacturing pressure sensitive adhesive tapes. All three companies showed high constitutive ratios of ethyl acetate and toluene. Also, regarding supplying achievements, RTO, which is known to show the most excellent removal efficiency of THC among the incineration-typed preventive facilities, shows 89.5%, which is the highest figure. We were able to see that the removal efficiency of THC shown by RTO increases as the temperature in the combustion chamber increases. In case of the 'T'company, after analyzing the removal efficiency of ceramic regenerative materials according to the changes of temperature in the combustion chamber in order to find out the energy-saving effect of RTO, we were able to see that when the temperature in the combustion chamber increased within the range of 95.2% to 96.0%, there was no change for the removal efficiency based on the temperature. However, in case of the 'I' company, when the temperature in the combustion chamber increased in the range of 650℃ to 850℃, the removal efficiency slightly increased in the range of 93.7% to 95.1%. At 800℃, which is the normal operating temperature of RTO in the combustion chamber, the removal efficiency of ceramic regenerative materials was around 95%. Such a result was similar to that of the previous one. As a result, it was possible to see that since the efficiency of the heat exchanger used in the direct combustion apparatus was within the range of 60% to 75%, the additional amount of fuel for RTO could be minimized with the use of ceramic regenerative materials. We were able to see that the related energy-saving effect would be extremely high. Also, the burner-operating ratio of RTO seemed to be influenced by such factors as the temperature in the combustion chamber, the density of the organic solvents which could be transformed into energy, and the removal efficiency of ceramic regenerative materials in a complicated way. After analyzing the energy saving effect based on the used amount of fuel at the 'S' company through which it was possible to compare the used amount of energy before and after installing RTO, we were able to see that it would be possible to save fuel up to 466,768,800 KRW annually. With the results of this study, we expect that it would be possible to provide various measures for environmental management, including the establishment of an approved standard for the restriction of pollutants discharged in the air from the process of manufacturing pressure sensitive adhesive tapes. Also, we believe that it would be possible to establish various related conditions while designing the preventive facilities for air pollution. It will be necessary to carry out a follow-up study for the contribution made by the gases discharged from the process of manufacturing pressure sensitive adhesive tapes to the quality of the atmosphere and the removal efficiency for the economic and efficient facilities used to the prevention of air pollution while developing related technologies.
