Feasibility Study of Simultaneous Removal of Sox and Nox via Combined Advanced Oxidation Process with Scrubbing

Project Details


As environmental protection consciousness gains ground, public pay more and more attention on the environmental issue. Air pollution problem has gradually evolved from a single pollution incident to a comprehensive and regional air quality management issue. In order to improve air quality, Taiwan EPA adopted the concept of Clean Air Act of the U.S. EPA as the basis to establish air quality management strategy. Small and medium-sized enterprises account for more than 90% of industries in Taiwan, and there are 12,623 medium and small-sized boilers. Due to ineffective control, air pollutants, such as PM, SOx and NOx, emitted by the boilers still contribute to local air pollution. However, few studies focus on developing air pollution control technologies which are suitable for small and medium-sized enterprises. Meanwhile, air pollution emission standards of boilers become more stringent starting in 2020, so it is urgent to find a new way to solve these problems. Our team will develop advanced oxidation process to help domestic small and medium-sized enterprises to remove SOx and NOx from coal-fired boilers. This method has the advantages of high energy efficiency, low cost, and simultaneous removal of SOx and NOx. The objective is to provide the best available control technology for domestic enterprises to effectively reduce SOx and NOx emissions and reduce the risks of public health.
