According to the comparing results between various emissions in last three years, all amounts are less than the allowance of permit in the top 10 emission processes. The integrity and consistency of reported data of air pollution fee are comparatively good. As the comparing results of testing data showed, the SOx emission concentration of power plant increased in 2008. Due to the impact of economic downturn, the usage rate of lower-quality coals increased for decreasing the fuel cost. 10 plants 20 members process the results of committee site inspections, Results, material and energy balance closed well, but there are intermediate products, raw materials undeclared vice flare operating regulations and conformity with the actual control efficiency concerns and other issues; Currently Sixth Naphtha tank emission estimation method is based on proven has confirmed that the fifth edition of AP-42 calculation, AP-42 fifth edition and fourth edition of the most important difference is that the loss of sealing the edge of the impact of wind, the Sixth Naphtha floating roof tanks are stamped, is not affected by wind speed, and therefore, Fourth Edition or the fifth edition, as calculated on the basis of their results are consistent, but some of the Islands by the VOCs storage tank program and the experimental results confirm that there are leaks and design of the actual vapor pressure vapor pressure are different, this will affect the results of emission estimation, it is need to be verified; water 9 wastewater treatment plant modeling and simulation to estimate the amount of VOCs emissions calculated with SCC cod comparison of the predicted results as expected water 9 SCC cod result is far greater than its estimated results due to water 9 VOCs mainly by wastewater species and concentration, waste water, processing unit scale factors, so the predicted results calculated over SCC cod objective, but the overall result is still greater than the estimated results SCC cod ; 21 manufacturers and 2009 of paint thinner total dosage 1166 tons, according to EPA 96 emission factor annual emission update the reference evaluates to 601 tons, and the other in accordance with SCC emission factor and Taiwan Paint Industry Association paints made by the individual emission factors were calculated to be 898 tons and 700 tons, if to offshore industrial zone and the proportion of the existing use of paint thinner agent solids ratio of 96 recommendations to EPA emission factor annual emission update the reference to calculate a more reasonable; Odor sampling and analysis for the year has completed 31 complaint cases, 12 item sources of pollution process area and perimeter sampling and analysis operations, statistics of the cases not measured 31 kinds of species, not the Sixth Naphtha the plant to declare the species accounted for 4 species and 31 species of methane accounted for 39% of species, followed by 23% benzene. The perimeter of the fingerprint data to investigate the results of sample analysis to detect species Ninety per cent of component analysis is almost in the discharge pipe can be measured, the other to process raw materials and reaction products. With the analysis results of the discharge pipe which provided by the outlying islands industrial park, there were 225 kinds of substances in total. Within those substances, there were 25 toxic and 17 were the priority regulated of hazard air pollutants (HAPs). Four petitions were proposed in outlying industrial park since July to September. With the two in July, acrolein were found out, exceeding the peripheral boundary emissions standard (2 ppb) while in two cases in September methylene chloride in six locations were highest in sample analyzing results of petition cases in last two years.
Besides, by the means of Sixth Naphtha Audit work scheduling meeting and the training courses taught by the experienced experts is conducive to improve the overall performance of the air pollution control of Sixth Naphtha. Enforcement agents can grasp the reasonable emissions of volatile organic compounds of the whole plant of Sixth Naphtha better. It’s not only helpful to succeed in the every work of this year to achieve anticipated target, but also good for improve effect of overall air quality management.
