中文摘要	本計畫主要工作內容包括：修訂發電業及玻璃業固定污染源最佳可行控制技術、強化固定污染源空氣污染物排放標準研修作業、檢討研修「揮發性有機物空氣污染管制及排放標準」、石化業揮發性有機物排放檢測及健全、落實加油站油氣回收政策推動工作等五大部分。固定污染源最佳可行控制技術修訂部份，針對電力設施發電鍋爐建議可加嚴至NOx及SOx皆為30ppm。而玻璃業槽窯NOx建議製程以空氣助燃排放濃度需小於或等於250ppm或排放削減率大於或等於30%；以純氧助燃使需符合排放量小於或等於1.85 kg/Gcal。針對「固定污染源空氣污染物排放標準」部分；TSP部分建議固體燃料標準依規模大小分別為50及150mg/Nm3，非固體燃料則為50、100及150mg/Nm3。SOx部分，建議應推動含硫分限值為0.3%之液體燃料，以質量平衡換算對應排放濃度標準150ppm；NOx部份，建議將現行既存污染源標準修正與新設污染源同一。修正生效後設立之污染源，以現行新設污染源標準加嚴20%削減率訂定。玻璃業部份，修訂NOx標準為以空氣助燃時，排放標準為300ppm；以純氧助燃時，排放標準為2.22 kg/Gcal。此外，砷為致癌性有害空氣污染物，亦規定製程使用原料不得含砷化物。研修「揮發性有機物空氣污染管制及排放標準」部分，廢氣燃燒塔主要修訂項目有：規範操作條件須符合設計條件；明定燃燒塔使用時機，含緊急、開車、停車、歲修及經主管機關審查同意之必要操作需求，使用時其VOCs空污費得以削減率98%計算；使用時機以每年不超過30日為原則，超過30日者，空污費需加計2倍計算。此外，為掌握排放情形，規定必須於燃燒事件進行廢氣成分分析，申報該事件污染物排放量，並對其成因進行探究，以減少其再次發生機會。設備元件部份，修訂項目包括：展延修護元件，檢測應比照定檢制度；展延修護期限之設備元件需經審查；接頭配件(含法蘭)不得展延修護；洩漏源應以修護前之濃度申報空污費；及展延修護設備元件須明確紀錄；洩漏定義值建議由2,000ppm修訂為1,000ppm；納入壓力槽設備元件為管制對象；規範大氣型釋壓裝置應連通密閉集氣系統；修訂洩漏管制規定為稽查數量小於等於200個時，洩漏源數量，不得大於三個，稽查數量大於200個時，洩漏源數量不得大於稽查數1.5%。揮發性有機液體儲槽部份，修訂包括：儲槽管制對象除考量蒸氣壓，亦應納入列管毒化物，管制對象新增「其它經主管機關指定公告者」；新增規定固定頂槽必須加裝約束釋壓閥；外浮頂槽之導向桿應採具襯墊之滑動封蓋、外浮頂汽油槽加裝頂蓋；內浮頂槽開口濃度不得高於爆炸下限30%(新設)或50%(既存)。本計畫完成150點次以上石化業設備元件檢測，發現氣體閥及輕質液泵排放係數呈降低趨勢，顯示國內洩漏率有降低趨勢。主要原因為現在多已逐漸汰換為更新為新型製程及元件，以致洩漏率有改善，但法蘭及輕質液閥則略為增加。健全及落實油氣回收作業推動政策部份，資料庫系統功能部分，已完成與土基會「加油站資訊系統」資料庫架構整併之前置作業。執行加油站油氣回收設備操作檢驗及維護輔導工作，發現氣漏檢測不合格原因主要為真空壓力閥(PV閥)洩漏，其次為管線鬆脫或漏氣問題。氣油比檢測不合格部分，以馬達抽氣功率異常為主要原因，其次為皮管積油，建議皆可透過日常巡查或操作保養提早發現或避免。

摘要	The contents of major work in this program include: the modification of best available control technology of stationary pollution sources for power plants and glass industries, the enhancement of air pollutant emission standard of ”Air pollution control and emission standards for stationary pollution sources”, the review of “Air Pollution Control and Emission Standard of Volatile Organic Pollutants”, the emission inspection of volatile organic matter for petrochemical industry as well as the fulfillment of petroleum recycling at gas stations. For the modification of best available control technology of stationary pollution sources, it is suggested that NOx and SOx emission standard for coal-fired power plants can be strictly limited to 30ppm. NOx for glass kiln with auxiliary-air is suggested emission concentration less than or equal to 250ppm or the emission reduction rate be greater than or equal to 30%; combustion supported with pure oxygen needs to meet emission less than or equal to 1.85 kg/Gcal. For the ”Air pollution control and emission standards for stationary pollution sources”, TSP is suggested the emission standards of solid fuel are 50 and 150mg/Nm3 according to the scale, and those for non-solid fuel are 50, 100 and 150 mg/Nm3 respectively. For SOx, it is suggested that the limit value of sulfur is 0.3% of liquid fuel, calculating with mass balance to respond to an emission standard of 150ppm; for NOx, it was suggested that the modification of current pollution source standard be consistent with new pollution source. The pollution source modified to take effective is strictly established at 20% of reduction rate with current pollution source standard. For glass industry, the emission standard is 300ppm when modifying the NOx standard as air combustion supporting; when combustion is supported with pure oxygen, the emission standard is 2.22 kg/Gcal. In addition, arsenic is a hazardous air pollutant with carcinogenic. Arsenide must not be contained in raw materials according to the regulations. In the review of “Air Pollution Control and Emission Standard of Volatile Organic Pollutants” for flares, the main modification is to specify the operating time. The operating conditions conform to the design conditions. The operating time must not be over 30 days annually. For those over 30 days, air pollution fees must be double calculated; moreover, in order to control the emission situation, wastes for special burning event must be specified to analyze. For equipment and component, the modified items include: the defined value of leakage is modified from 2,000ppm to 1,000ppm; equipment and component fitted into a pressure tank are under control; pressure relief devices shall be connected to the closed collection system; the leakage regulations are modified the number of leakage source must not be greater than 3 when the audit number is less than or equal to 200 and the number of leakage source must not be greater than the audit number of 1.5%, when the audit number is greater than 200. For the volatile organic liquid tank, the modifications include: the tank targets consider vapor pressure and hazardous chemicals; new fixing roof tank must be installed with a pressure relief valve; a guide on external floating roof tank shall be installed with a slit cover. An external floating roof tank is installed with a roof cover; the concentration at an opening of internal floating roof tank must not be greater than the lower limit of explosion 30% (newly installed) or 50% (existing). This program completes over 150-point inspections of equipment component for petrochemical industry. It is found out there is a trend to decrease the emission coefficient of gas valve and light liquid pump, showing a decreasing trend of the leakage rate in Taiwan. The main reason is that novel processing and components have been gradually replaced, so that can improve the leakage rate. However, the leakage rate of flange and light liquid valve roughly increases. In order to soundly fulfill petroleum recycling policy, the functions of database system have completed a preparation for combining a database architecture of ”Gas Station Information System” with the Soil Foundation. When performing an inspection and maintenance of petroleum recycling equipment at a gas station, we can find out the main reason why a leakage inspection fails is due to a leakage of vacuum pressure valve (PV valve), following pipe looseness or leakage. The main reason why the gas-oil ratio fails is due to abnormal motor pumping power, following oil accumulated in a tube. We suggest they can be found or avoided in advance via daily inspection or maintenance.
