固定式OP-FTIR監測工業區周界大氣醋酸乙烯濃度

本研究係蒐集高雄市仁大工業區周界民國101-106年間固定式OP-FTIR監測站VA監測數據及氣象資料，包括：VA出現頻率、濃度、超標頻率及超標時數等，並比對VA主要排放源A廠於增設RTO防制設備前/後OP-FTIR監測站VA監測濃度的差異，除可分析VA是否主要係由A廠貢獻外，亦可驗證A廠增設RTO對處理VA是否有效。研究結果顯示：由民國101-106年間仁大工業區周界固定式OP-FTIR監測站VA監測監測數據及氣象資料分析結果推論：仁大工業區周界大氣VA主要來自於A廠貢獻；且由VA監測數據分析可知：民國104年後VA監測濃度與超標情況有明顯降低趨勢，推測與A廠增設RTO防制設備有關。A廠民國103年底完成廠內製程設備元件汰舊換新及增設RTO防制設備後，周界固定式OP-FTIR監測站VA連續監測數據有明顯降低，至民國106年夏季間VA監測值較往年減少近85 %，顯示：製程設備元件改善及增設RTO防制設備可有效降低VA逸散及排放。

This study collected the meteorological and Vinyl Acetate (VA) data of the Ren Da Industrial Park and it’s surrounding regions obtained by fixed Open-Path Fourier Transform Infrared Spectrometry (referred to as OP-FTIR) monitoring stations in 2012–2017. Said data included VA occurrence frequency, concentration, frequency of VA content exceeding the standard concentration, and the duration of VA content exceeding the standard concentration. This study compared the VA concentration of Plant A (the primary contributor of VA emissions) before and after the installation of Regenerative Thermal Oxidizer (RTO) control equipment. The comparison enabled this study to determine whether Plant A was the major contributor of VA and whether the RTO was effective in treating VA. The results showed that Plant A was the major contributor of VA in the Ren Da Industrial Park and it’s surrounding regions. VA concentration decreased considerably after 2015, and the RTO control equipment might cause the decrease. Plant A replaced its manufacturing equipment and installed RTO control equipment by year-end 2014, after which the VA concentration decreased substantially. By summer 2017, VA concentration decreased by approximately 85%, signifying that improving manufacturing equipment and installing RTO control equipment can effectively reduce VA diffusion and emissions.
