With maturing control technology and implementation of control policy, Taiwan started seeing good results in air pollution minimization. Flue gas and ash generated after combustion of stationary pollution sources contain heavy metals that create a long-term effect on ecological environment and human health. The accumulation and persistency of mercury emission has caused serious concerns. To protect environment and human health, the project aimed to study mercury emission from stationary pollution sources.
The project completed data collection and analysis for 19 large domestic incineration plants and 10 times of mercury sampling and analysis for domestic plants. The project also conducted mercury flow distribution test study for one coal-fired power plant and one coal-fired cogeneration plant. For establishment of mercury emission factor, besides collecting data from domestic and international sources as references for comparison, the project also completed the design of questionnaire to estimate and assess total mercury emission from domestic stationary pollution sources. The project completed the derivation of the first domestic mercury emission factor.
The project also conducted assessment on the latest analytical technique and continuous emission monitoring technique for mercury species. To assure mercury sampling and analyzing capability, the project completed a quality assurance project plan (QAPP) and obtained good results by collaborating with US EPA in mercury sample matching analysis. Furthermore, the project completed an extensive evaluation on mercury emission control technology in terms of technology status, equipment cost, technology potential and control efficiency. The project also drafted a plan and suggestions on mercury emission control policy for domestic coal-fired power plants with references to domestic stationary pollution sources status and US mercury emission regulations.
