dc.description.abstract | Along with the rapid development of semiconductor and related industries, emission of volatile organic compounds (VOCs) in Taiwan has increased sharply. This research evaluates the effectiveness of applying activated carbon fibers as concentration device and low-temperature catalytic oxidation as treatment technology for VOCs removal in an electronics manufacturing company (Plant A). The VOC components include toluene, isopropanol, and 1-butanol. Continuous Emission Monitoring System (CEMS) data from Plant A were collected to explore the removal efficiency and operating cost for removing volatile organic compounds. Additionally, economic viability compared to other adsorption-desorption and oxidation systems is also analyzed. The results show that as the inlet concentration of VOCs reaches 1000 ppm, the desorbed gas can reach the temperature required for desorption after passing through the heat exchanger. As the inlet concentration is low (about 400 ppm), additional energy is needed for the heater and oxidizer. The energy consumption of the system is mainly attributed to the catalytic oxidation system, with the CO2 emission of 233.19 tons CO2e per year, which is 47.6% lower than that of regenerative thermal oxidizer (RTO) system. In terms of removal efficiency, the overall VOCs removal efficiency achieved is greater than 90% and meets the emission standards of Plant A, indicating effective removal of volatile organic compounds. In terms of economic benefits, the catalytic oxidation has lower operating costs than the thermal or regenerative thermal oxidizer, primarily due to its lower operating temperature and higher heat exchange efficiency. | en_US |
