108年度雲林縣離島工業區揮發性有機物查核計畫

 中文摘要 本計畫主要的工作項目為專案列管本縣離島工業區揮發性有機物污染源管制業務。確實監督離島工業區揮發性有機物污染源之污染排放,並進行揮發性有機物污染源查核、檢測作業與後續追蹤管制作業,提昇離島工業區VOCs查核管制及排放減量成效,以維護本縣空氣品質並減少對於民眾健康的衝擊。自決標日(108年01月01日)開始執行迄今,均依合約規定、原規劃之工作項目及執行方法,並於執行截止日前(108年12月31日)完成期末報告工作量,其主要成果摘要如下: (一) 離島工業區揮發性有機物排放量自103年2,815.15公噸降至108年為2,551.01公噸。其中設備元件、儲槽、排放管道為前三大污染源,油漆塗佈逸散量則逐年增加。 (二) 列管石化製程排放管道及防制設備法規符合度查核共完成30製程,查核結果均符合規定;另針對列管石化製程排放管道共完成揮發性有機物(或單一污染物苯、甲苯、二甲苯等項目)稽查檢測12根次,分析結果均符合操作許可證排放標準。 (三) 離島工業區廢氣燃燒塔已完成42座法規符合度查核,其中台塑石化公司輕油裂解二廠於10月12日因製程開車導致燃燒塔廢氣流量大於無煙設計值,已逕行告發。透過廢氣回收及製程正常操作下不得使用燃燒塔進行排放之管制策略,燃燒塔使用事件日及揮發性有機物排放量逐年下降。針對使用頻率較高之業者如長春石化公司麥寮廠及台灣化學纖維公司聚丙烯廠等,建議作為後續管制重點,持續要求業者優化操作,精進管制。 (四) 列管儲槽法規符合度查核共343座,查核結果業者均依規定進行操作;儲槽設備元件稽查檢測作業共909個,均未發現洩漏。另持續輔導業者進行儲槽廢氣回收改善措施,自103起至107年共146座儲槽完成改善,揮發性有機物逸散量亦大幅下降,將持續輔導業者進行改善以減少揮發性有機物逸散。 (五) 列管裝載場法規符合度查核共46座,查核結果業者均依規定進行操作;另裝載場設備元件稽查檢測作業共1,019個,均未發現洩漏。 (六) 廢水設施氣密量測作業共28座,台塑石化公司輕油裂解一廠油水分離池I001最高淨檢值3,997.8ppm,未保持氣密狀態,已逕行告發。目前離島工業區針對久未使用且仍有逸散疑慮之油水分離池均已逐步申請拆除作業,以減少揮發性有機物之逸散。 (七) 製程設備元件洩漏檢測共11,601個,其中大於洩漏定義值(1,000ppm)共21個,業者均依規定於24小時內完成修護並經承辦人員確認無誤;另台塑石化公司輕油裂解一廠發現1個元件大於洩漏管制值(10,000ppm)及大連化工設備元件1個元件未依規定建檔,均已逕行告發。透過無預警之稽查檢測方式督促業者於平日確實進行自主管理及確實修護,設備元件洩漏率及逸散率均逐年降低。 (八) 針對離島工業區內應配合應變或達預警排放量規模之工廠,執行空品惡化防制計畫書現場查核共59製程。業者均依規定配合應變作業,粒狀污染物削減量537.35公斤、硫氧化物削減量2,660.42公斤、氮氧化物削減量6,480.74公斤及揮發性有機物削減量565.63公斤。

The 2019 Project of VOC inspection in offshore industrial zones, Yunlin County

  摘要 The main task of this plan is to manage the volatile organic pollution source control of the offshore-island industrial zones in the County by project. It is to effectively monitor the emission of volatile organic compound pollution sources in the industrial zones of offshore islands, and conduct inspections, testing and follow-up control of volatile organic compound pollution sources, and to improve the effectiveness of inspection, control and emission reduction of VOCs in the offshore-island industrial zones, so as to maintain air quality of the county and reduce impact on public health. Since award of the bid (January 1st, 2019), all planned work items and execution methods have been completed in accordance with the contract. Final report has been accomplished before the end of term (December 31st, 2019). The major outcomes are summarized as follows: (1) VOCs emission from the offshore-island industrial zones decreased from 2,815.15 metric tons in 2014 to 2,551.01 metric tons in 2019. Among the pollution sources, components of equipment, storage tanks, and drainage pipes are the top three pollution sources while the amount of fugitive emission of paint coating is increasing year by year. (2) 30 controlled petrochemical processes were inspected for whether the drainage pipelines and pollution control equipment are in compliance with regulations. All 30 processes were found in compliance with the regulations. In addition, 12 inspections on VOCs (or single pollutant such as Benzene, Toluene, Xylene, etc.) in the controlled petrochemical process drainage pipelines were conducted. All results of analysis were in accordance with the emission standards of operating permits. (3) Inspections for compliance with regulations on 42 flare towers of the offshore-island industrial zones have been completed. Among them, the 2nd Naphtha cracking plant (OL2) of Formosa Petrochemical Corporation due to process startup has emitted exhaust over the flare smokeless design capacity, and has been reported on October 12. Through the control strategy of exhaust recycling and no emission from flare tower under normal process operation, the use-event day of flare tower and emission of VOCs are decreasing year by year. For those whose flare towers run more frequently, such as the Mailiao Factory of Chang Chun Petrochemical Co., Ltd. and PP Plant of Formosa Chemicals & Fiber Corp., it is recommended to put them on focus of control and continuously request those companies to optimize operations and improve control system. (4) 343 classified storage tanks in total were inspected for compliance with regulations. All tanks were found operating in accordance with the regulations. 909 inspections on equipment components of storage tanks were completed, and no leakage was found. In addition, we continuously gave advice to the companies to carry out storage tank exhaust recycling improvement actions. From 2014 to 2018, totally 146 storage tanks have been improved. Emission of VOCs has also been significantly reduced. We will continue to give advice the trade to reduce VOCs emission. (5) 46 controlled loading yards were inspected for compliance with regulations. All 46 yards were found operating in accordance with the regulations. In addition, 1,019 inspections on equipment components of loading yards were completed. No leakage was found. (6) Airtight tests were conducted on a total of 28 effluent facilities. The highest net measured value of oil-water separation tank (I001) of the 1st Naphtha cracking plant (OL2) of Formosa Petrochemical Corporation is 3,997.8ppm, and the company has been accused of failure of air-tightness. At present, the oil-water separation tanks in the offshore-island industrial zones which have not been used for a long time and doubted for fugitive emission is gradually applied for dismantlement so as to reduce the emission of VOCs. (7) Leakage inspections were conducted on 11,601 process equipment components. 21 out of them were found over leakage ratings (1,000ppm). Those companies have repaired the leakage problems in 24 hours according to the regulations and problems were confirmed resolved by the case officer. In addition, the 1st Naphtha cracking plant (OL1) of Formosa Petrochemical Corporation has been accused of leakage of 1 component over 10,000ppm. Dairen Chemical Corporation has been accused of 1 unfiled component according to the regulations. Through non pre-warning audit inspection, the companies were urged to carry out self-management and substantial maintenance on weekdays, and leakage rate and fugitive emission rate of equipment components is reduced year by year. (8) On-site inspections were made on air quality deterioration prevention and control plans of 59 factories that should cooperate with the emergency response or reach the alert level of emission in the offshore-island industrial zones. All factories inspected have cooperated with the emergency response operation in accordance with regulations. Reduction of granular pollutants was 537.35 kg, reduction of sulfur oxides was 2,660.42 kg, reduction of nitrogen oxides was 6,480.74 kg, and reduction of VOCs was 565.63kg.
