The execution of this project spans a nine-month period from April 1 to December 31, 2011. The tasks chiefly include:1. Allocating adequate human power for the execution of the related checking and auditing in this project. 2. Performing the checking and control of equipment components, where over 50,000 times of checking and control on components, at least ten processes and on-site quantity checking of at least 10% of controlled components in off-shore industrial parks were completed; also made was 100 hours or more of the checking of equipment component leakage by using “IR image gaseous leakage detector” and 20 rounds of checking on equipment components in VOC loading yard. 3. Completing the checking and investigation of controlled reservoirs and VOC emission measurement in over 20 reservoirs using continuous automatic monitoring instruments. Testing the exhaust composition at 44 samples of exhaust flares to be comprehensive of the flare exhaust composition. Holding two meetings on emission measurement and optimal viable control technology at loading yards in off-shore industrial parks. 6. Assisting in the execution of polluting source management and performing the stationery polluting source-related emergency responses on the occasions of air quality deterioration or severe air polluting incidents in the County. 7. Having the personnel stationed within 10 days after project execution began and completing prior training for the staff. 8. Allowed to autonomously consult and be assisted by experts in case of accidental air pollution and joining review meeting with the Bureau on the County’s SIP project tasks.
Currently the number of controlled factories is 21, and that of valid permits is 173, including 163 permits to operate and 10 permits to install. As of September 30, 2011, the number of processes having been completed in construction in off-shore industrial parks was 168, accounting for 84.8% of the estimated construction under environmental assessment.
There are 393 chimneys, 1,878 reservoirs, 1,986,362 equipment components (1,896,269 at time of signing contracts), 135 loading yards and 45 flares in off-shore industrial parks. Of the above, 40 chimneys are at the plastic crackers, taking the biggest share at 10.12% of all the chimneys, followed by 22 each at the #3 Olefin plant and the Formosa PVC plant, each accounting for 5.56%. Formosa Cracker has the most reservoirs, 290 of them accounting for 15.44% of total, followed by Formosa Chemical Terminal Storage Tank Area with 404, accounting for 6.07% and Dairen Chemical Corp. at Mailiao, with 106, 5.64%. Formosa Cracker has the most equipment components, 462,315 of them accounting for 24.13% of the total number of controlled components, followed by Formosa Chemical #3 aromatic hydrocarbons plant, with 125,162 components, which is 6.53% and Formosa Chemical #2 aromatic hydrocarbons plant, with 71,163 components, 3.71%. 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 Olefin plants and Dairen Chemical Corp. at Mailiao, 6.66% each.
Concrete results of tasks during the execution period of this project included: the completion of 94 times of counting of equipment components at factories, of which were 10 single processes having been fully counted, resulting in up to 208,800 components, representing 11.01% of the signed quantity, also the discovery of 439 components without file created, of which valves were the greatest majority, next to which were pipe threads.
The checking of a total of 51,003 equipment components was completed. These components came in the types of flange (F), at 256120 locations, valves (V), at 13857 locations, opening (O), at 4153 locations, pump (P), at 357 locations, relief valve (R), at 17 locations, sampling joints (S), at 147 locations, other joints (N), at 6102 locations and goose-tube, at 597 locations. Also made was the inspection of six pipelines, with 12 locations found with concentration higher than the leakage controlling value of 10,000ppm; these have been dealt with by NT$1.2 million of fine.
The IR image gaseous leakage detection (FLIR) completed a total of 102 hours of screening by imaging in 40 petrochemical processes in 20 operations, and found 17 cases of leakage. Of the leaking points, pipeline leakage was most common, 7 cases of it, representing 41.2%, followed by valves, in 3 cases, 17.6%, flanges, in 11.8 cases, 25% and pumps, in 2 cases, 11.8%.
A total 770 reservoirs have undergone checking of legal compliance, of which 264 were fixed on-top reservoirs, 244 internal floating on-top reservoirs, 40 external floating on-top reservoirs and 222 pressurized reservoirs. The checking results discovered 250 of them with flaws in four types: 1. incorrect information, 2. failure to maintain hermetic condition, 3. being under new control, lack of preventive and controlling devices, and 4. missing information on floating on-top reservoirs.
The checking of organic liquid reservoirs resulted in top three measurements: T008 concentration at 28,436ppm in the fixed on-top reservoir at the Mailiao plant of Chang Chun Group, TN34 at 9,034 ppm in the internal floating on-top reservoir at Formosa Chemical #2 aromatic hydrocarbons plant, and TF06 at 7,521ppm in the internal floating on-top reservoir at Formosa Chemical #3 aromatic hydrocarbons plant. The assumed 1,000ppm as the criterion for determining hermetic condition achieved was exceeded by the tested maximum value at 7 reservoirs. Additionally, of the 20 reservoirs under test during the execution of the project, 13 were with highest value below 1,000ppm, of which 12 were internal floating on-top type and only 1 fixed on-top type; the rest were over 1,000ppm, 3 being fixed on-top type and 4 internal floating on-top type.
The flare emission composition checking completed analysis in 44 flares. Those containing hydrogen sulfide which also exceeded the criterion of 650ppm were AR02 and AR04 at Formosa Cracker. There were also 8 flares found with benzene content, Formosa Chemical #2 and #1 aromatic hydrocarbons plants and synthetic phenol plant of Formosa Chemicals ＆ Fiber Corp. being the worst; also, 13 flares had ACN, #1 ARO plant of the same corporation being the worst.
