소형전기로를 이용한 플라스틱류 소각시 발생하는 VOCs 농도분석
이병규,김행아 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.6
This study analyzed concentrations of volatile organic compounds (VOCs) produced from incineration of plastic wastes at 600℃ The plastic wastes used in this study included polyethyleneterephthlate (PETE), high density polyethylene (HOPE), polyvmyl chloride (PVC), low density polyethylene (LOPE), polypropylene (PP), polystyrene (PS) and other Plastic wastes were heated from room temperature upto 600°C providing the compressed air inside of a small-cale electric furnace for 90 minutes and then they were oxidized (incinerated) for 60 minutes at 600℃ maintaining the same air supply VOCs emitted from the incineration process were sampled using an air sampling pump and Tedlar air bags for 150 minutes and then the components and concentrations of the VOCs were analyzed by a GC-MS The most prominent chemical structure of the VOCs obtained from the Incineration process of the HOPE, LDPE and PP, which Include ethylene groups In their main chains, was identified as aliphatic hydrocarbons such as l-hexcne However, aromatics such as benzene were major chemical structure from the Incineration of PETE, PVC and PS which include benzene lings in their main chains This study estimated the total VOC production from the incineration of the plastic wastes based on the real plastic waste production and the emission factors 64% and 27% of the total vac emissions consisted of aliphatic hydrocarbons and aromatics, respectively, which have double bonds within their molecular structure and thus a high ground level ozone formation potential
