The execution of this project spans a nine-month period from April 2 to December 31, 2012. The main objectives: 1.Of volatile organics air pollutant emissions of major pollution source checking and testing operations for six light offshore industrial park, and regulatory advocacy and checking work to reduce emissions of volatile organic compounds in air pollutants, and to the implementation of laws and regulations. 2.Assess their emissions by air pollutant emissions of volatile organic compounds in the status of investigations. 3.Strengthen the raw material conveying pipeline's leak detection to reduce the large number of leaks of volatile organic compounds in air pollutants. 4.The implementation of the Air Pollution Control Act on the control of volatile organic compounds in air pollutants, contributed to the reduction in emissions.
Currently the number of controlled factories is 21, and that of valid permits is 172, including 162 permits to operate and 10 permits to install. As of December 31, 2012, the number of processes having been completed in construction in off-shore industrial parks was 171, accounting for 86.4% of the estimated construction under environmental assessment. There are 398 chimneys, 2,094,699 equipment components (the third quarter of 2012), 2,148 reservoirs, 142 loading yards and 45 flares in offshore industrial parks. Of the above, 40 chimneys are at the plastic crackers, taking the biggest share at 10.05% of all the chimneys, followed by 22 each at the #3 Olefin plant and the Formosa PVC plant, each accounting for 5.56%. Nan Ya Plastics Corporation Mailiao plant has the most reservoirs, 558 of them accounting for 25.97% of total, followed by the Formosa Cracker Mailiao first plant with 346, accounting for 16.10%. Formosa Cracker Mailiao first factory has the most equipment components, 559,674 of them accounting for 26.71% of the total number of controlled components, followed by Formosa Chemical Haifeng plant, with 380,795 components, which is 18.17% and Formosa Chemical Mailiao plant, with 202,990 components, accounting for 9.69%. Formosa Chemical Terminal Storage Tank Area has the most loading yards, with 28 of them, accounting for the largest 20.74% of all controlled number, followed by Dairen Chemical Corp. at Mailiao with 20 yards, 14.81% and Formosa Cracker plant with 16, 11.85%. There are currently 45 controlled flares in all, of which six are at Formosa Cracker plant, accounting for the biggest 13.33%, and three at each #2, #3 Formosa Naphtha Cracker plants and Dairen Chemical Corp. at Mailiao, 6.66% each.
Concrete results of tasks during the execution period of this project included: the equipment components inspectors detected a total of 50,006 points, its public and private premises equipment component concentration distribution range in table 6.2-6、Equipment element detects the type and concentration distribution. To various public and private spaces leakage points and component types to compare the leakage concentrations exceeding 1,000 ppm, and the Formosa Mailiao plant within the range of 1,001 ~ 2,000 ppm majority, the leak quantity to 15; within the range of 2,001 to 10,000ppm, continue to Formosa Mailiao plant number of leaks is the largest leak the quantity of 13. The leaks concentration more than 10,000ppm is Formosa Mailiao plant, the leak quantity to 4. Integrated the above leakage of information learned types of components leak to the large quantity of the valve(V) member, that is because the components leak points are often actuated. The flange(F) is followed easily leak, that is because the leakage point is ended drain pads, between the elements in the the repeatedly pressuring locking, the amount of deformation of the gasket per unit area reaches the limit, and will cause the gasket deformed to cause fluid leakage.
The IR image gaseous leakage detection (FLIR) completed a total of 208 hours 29 minutes of screening by imaging in 68 process and 3 shared pipeline, pipe rack screening, and found 16 cases of leakage, leak form of the Table 6.2-32. There are a total of eight above the leak definition of a value of 1,000ppm, and seven more than the leakage control value of 10,000ppm (Refer to Table 6.2-30).
The fixed tank airtight testing operations completed a total of 91, and the process of checking found six(4 old, 2 new) fixed roof tank opening concentration> 1,000ppm. For additional control part of the storage tank regulation compliance inspection, that republic of fixed roof storage tanks 36, 20 tank which is not already installed control equipment, there were 10 each tanks belongs to Formosa Chemical SM3, SM1 and SM2 plant, and the rest of the new additional tube tank were completed to improve.
Organic liquid storage tank testing operations section, completed a total of 20, which contains the internal floating roof 11, 9 external floating roof. The measurement results of the highest detection value greater than 1000ppm tank, the main storage oil storage material for light oil and gasoline. Measuring the concentration of tank feeding or discharge relationship, that found by the test results, when the tank feeding level rises and concentration will rise, and material level drops concentration also decreased, but if tank nitrogen seal and will allow the tank concentration by dilution affect measured value.
The flare emission composition checking completed analysis in 11 flares. Those containing hydrogen sulfide which also exceeded the criterion of 650ppm were A203 and AR05、AR06 at Formosa Cracker. There were also 9 flares found with benzene content, Formosa Chemical #3 aromatic hydrocarbons plants and Formosa Naphtha cracking #1 plant. being the worst.
