1. This project reviewed the air pollution control fees of gasoline and diesel fuel from January to December this year. During this period, The total accumulated sales volumes of gasoline and diesel fuel were 9,709,000 and 4,512,000 kiloliters, respectively. The imposed air pollution fees were NT$ 1,037,000,000 for gasoline, and NT$ 576,000,000 for diesel fuel.
2. This year, samples were analyzed taken from 221 gasoline storage tanks and filling stations, as well as 206 diesel fuel storage tanks and filling stations. All the samples met the spec’s of the current control standards. Two (2) mobile pollution source network reporting system combined with electronic fund transfer system conferences were held and both CPC Taiwan and Formosa Petrochemical have been using the system to process reports on air pollution fees.
3. In this year, a field audit was completed for eight bio-diesel factories. Among them, Jieshen Enterprise, Ltd. has not produced bio-diesel for more than two years. Yuehong, Ltd. has ceased production because the Environmental Protection Administration Executive Yuan, R.O.C. (Taiwan) has designated the factory site as a pollution remediation site. Hoeway Energy Tech, Ltd. has ceased operations and could not be contacted. The bio-diesel samples from Chendeh Oil & Grease, Ltd., Shechaw Tech, Ltd., Honjeih Energy, Ltd., Jinteng Energy, Ltd. and Hsinjehaw, Ltd. were inspected, and the sulfur contents and total aromatics both met the control standards.
4. The International Convention for Prevention of Pollution of Ships (MARPOL) has recently mandated a reduction in the maximun allowable sulfur content in Residual Marine Fuels (RMF) from 4.5% (m/m) to 3.5% (m/m) beginning in January 1, 2012. Ultimately, the maximum allowable sulfur content will be reduced to below 0.5% (m/m) by January 1, 2020. As for ships sailing in a Sulfur Emission Control Area, such as Baltic and North Sea, the maximum allowable sulfur content in RMF will be reduced from 1.5% (m/m) to 1.0% (m/m) beginning July 1, 2010, and then be further reduced to 0.1% (m/m) by January 1, 2015.
5. The inspection of 36 suspected illegal diesel fuels was completed this year. Of those, 2 samples had added waste solvent mixed with benzene ring and total aromatic contents exceeded the mandated upper limits of the control standards. 8 of those samples had the sulfur contents exceeded the mandated upper limits of the control standards.
6. The audit information of illegal oils collected during the road check of vehicle by the Environmental Protection Department of all Counties and Cities in the first to third quarters was analyzed. Of the 74,544vehicles samples checked, 41 samples were found not in compliance with the control standard, and the defective rate was 0.06%.
7. the project assisted twelve (12) County and City Environmental Protection Departments (EPDs) in establishing relevant inspection methods for illegal oil by using a portable density meter. Efforts were also made to understand current auditing methods of the illegal fuels by the local EPDs.
8.The Illegal Fuel Inspection Team held a meeting on January 25, during the meeting, the 2009 execution results of oil auditing work were reviewed. Auditing experiences were shared with the local EPDs.
9.Based on the tests, regardless of either the FTP or NEDC vehicle driving modes were used, increasing the olefins content in gasoline does not significantly influence exhaust emissions in CO, CH4, HC, NOx, and CO2.
10.Based on the tests, regardless of either the FTP or NEDC vehicle driving modes were used, increasing the aromatics content in gasoline does not significantly influence the exhaust emissions in CH4. It was found that under the FTP vehicle driving mode, the CO, HC, NOx, and CO2 emissions increased with an increase of aromatics content in gasoline. Increasing the aromatics content in gasoline does not significantly influence exhaust emissions in CO, HC, and NOx under the NEDC vehicle driving mode.
11.The VOCs emissions from three different olefins contenting gasolines were compared. Based on the test results, regardless of either the FTP or NEDC vehicle driving modes, the average emission of toluene decreased with an increase of olefins content in gasoline. Under the NEDC driving mode, The average emission of 1,3-butadiene increased as the olefins content in gasoline inscreased.
12.Under the FTP driving mode test, the average emissions of benzene, toluene and ethylbenzene increased with an increase of aromatics content in gasoline. Under the NEDC driving mode test, the average emissions of benzene, toluene, ethylbenzene, p-xylene, 0-xylene, and m-xylene increased with an increase of aromatics content in gasoline.
13.Results from exhaust by adding gasoline with different contents of olefins or aromatics showed that the distribution of PAHs were mainly in the gaseous phase. Increasing aromatics content, the results were consistent with ascending trend of gaseous PAHs concentrations, while different additives contents did not show obvious influence on particulate PAHs concentrations.
