Continuously to introduce new technology on air pollution prevention and control, and examines existing facilities and production process regularly. To ensure regulatory compliance and help reach reduction targets.
Air Pollution Management Guidelines and Measures
The emission of air pollutants saw a dramatic decline of 16% in 2020, and emission per unit production decreased by 18%, which is the equivalent of 0.05kg/metric ton. The numbers reflect the effectiveness of FENC’s strategies in upgrading equipment and facilities as well as managing the source of air pollution. Among the Businesses, air pollutants from Petrochemical Business increased by 23% in 2020. The increase is attributed to the catalyst used for exhaust treatment at OPSC, which is approaching the end of its 5-year life cycle. The decline in catalyst activity results in higher concentration of pollutants in the exhaust, it has purchased new catalyst and replacement will take place in June 2021 during the turnaround period. OPSC also invested in a new exhaust treatment facility that is scheduled to be completed and in operation in September 2021, which will further reduce the concentration of pollutants from the exhaust. For Polyester Business, the measures reduced air pollutant emission for the entire Business by 31% in 2020, because of Hsinpu Chemical Fiber Plant replaced the heavy crude oil boiler with natural gas boiler; FEFC cuts back on steam processing; FEIS revamped the production process with low nitrogen transformation.

1. Only gases emitted are listed.
2. Particulate Pollutants include particulate matter (PM), dust and smog.
3. The data includes four types: actual measured values, annualized sample values, calculate values, and permitted amounts of emissions. Actual measured values come from Hsinpu Chemical Fiber Plant (NOx, SOx, particulate pollutant), Kuanyin Chemical Fiber Plant (NOx, SOx, particulate pollutant), FEFC (NOx, SOx), polyester plant of FEPV, the second plant of OPTC, OPSC (NOx, SOx), WHFE, Kuanyin Dyeing and Finishing Plant, FEIW, FEDZ, FEAZ, FEAV and FENV; annualized sample values are from OPSC (VOC), FEIS and textile plant of FEPV; calculated values are from the first plant of OPTC, Hsinpu Chemical Fiber Plant (VOC), Kuanyin Chemical Fiber Plant (VOC), OGM, FEFC (VOC) and Hukou Mill, FIGP and APG Polytech; permitted amounts of emissions are from OTIZ.
4. Data on hazardous air pollutants (HAP) are provided by APG Polytech in the U.S. and FIGP in Japan. The 3 HAPs identified at APG Polytech are MEG, acetaldehyde and 1,4-Dioxane, which are regulated by U.S. Environmental Protection Agency. Acetaldehyde, which is on the list of HAPs regulated in Japan, is identified at FIGP.
