97-voc Abstract
Absrtact |
As of 1997, the Environmental Protection Administration (EPA) of the Executive Yuan has published regulations concerning volatile organic compounds (VOCs), thus making clear the administration’s intentions to control VOCs. In this year’s project, fixed pollutants, petrol stations and the catering sector are the 3 major targets; the reduction of VOCs is achieved via increased inspections, regulations, assistance and promotion from the government.
The project contract was signed and executed on June 24, 2008 and terminated on May 30, 2009; in total, the VOCs from 406 fixed pollutants were checked, in which 127 failed to conform to regulations, with a failure to pass rate of 31.4%, in particular the main faults include improper operation of prevention equipments, and allowable discrepancies which accounted for 53.8%. Petroleum processing equipments were inspected with FID instruments, totaling 5199 spot tests in 53 occasions. In particular, 12 production processes were inspected in CPC’s Taoyuan oil refinery; significant differences were discovered between actual test data and the data reported by the Taoyuan oil refinery.
Overall, 0.23% of the inspected cases revealed a statistic of C (Leakage concentration) >10000ppm. In addition, canister sampling inspections were carried out in factories in industrial zones for pollution, as per complaints and requests filed by the public; in total, 55 spot tests were conducted in 14 locations. In general, test results were within the legal emission limit. However, a majority of the pollution samples gathered were associated with stack emissions, and the volumes were highly significant, indicating that local people’s complaints were influenced by stack emissions. With regards to the emission of VOCs in fixed pollutants, 55 spots testes were conducted in 32 locations for NMHC stack emissions. In particular, 14 tests from 10 locations failed the inspection, with a failure to pass rate of 29%. In addition, seasonal reports from special industries (petroleum, semiconductor, optoelectronic, car manufacturer, PU synthetic leather manufacturer) were verified, and assistance was provided to the manufacturers in terms of correctness and completeness of data when filing for
