中文摘要 | 煉油廠及石化廠VOC主要來自設備元件的逸散排放,而洩漏嚴重的設備元件(濃度高於一萬ppm者)數量雖佔不到1%,但VOC排放量卻佔了總排放量近90%,因此VOC減量需從洩漏嚴重的設備元件著手,才能事半功倍。紅外線氣體顯像查漏法可快速查到嚴重洩漏的設備元件,並且「看到」洩漏狀況及洩漏位置,以便做出正確的維修。另外,紅外線氣體顯像查漏法具遙測功能,特別適用於難以接近及高處的設備元件查漏。文中彙整作者使用FLIR GF300紅外線氣體顯像查漏儀六年多的經驗及心得,並將收集到的文獻、資料做整理,以供各位石化業先進做參考,包括介紹目前市售的FLIR GF320及GF306的功能及特色,另外介紹OPGAL Eye-C-Gas的特色,並與FLIR GF320做比較。此外,也介紹美國環保署對該方法推廣情形及方法驗証結果。未來,發展方向可能朝降低可顯像的最低濃度及可測出濃度兩方向邁進。 |
英文摘要 | In a refinery or petrochemical plant, VOCs mostly derive from the fugitive leakage of components, such as valves, flanges, vents, and pumps. The major leakages (> 10,000ppm) take up less than 1% of the components, but contribute about 90% amount of total VOCs to the atmosphere. This fact indicates that we had better target major, instead of minor, leakages in order to abate VOCs effectively and economically. Infrared gas imaging is a novel leakage-detector for discovering major leakages, especially for components inaccessible or at the height. It is helpful to identify where the leakage is from and how it behaves. After that, the leaking components can be repaired or replaced correctly and quickly. The experience of 6 years of use is summarized and four types of leakage-detectors on the market are introduced, including FLIR GF300, FLIR GF320, OPGAL Eye-C-Gas and GIT Sherlock. The promotion and accreditation of this tool by US EPA are mentioned as well. Both lower detection limit and ability to measure the concentration are our expectations in the near future. |
