Costs and Benefits of Installing Flue-Gas Desulfurization ...

India, which relies on coal to generate 76 percent of its electricity (CEA 2015), did not regulate SO 2 emissions from coal-fired power plants until December 2015. That lack of regulation may have been due, in part, to the low sulfur content of Indian coal (Chikkatur and Sagar 2007).

2021-2-1  Coal combustion is the single largest source of mercury emission in India, and coal fired power plants are major contributor in this sector. Mercury contents in Indian coal, is typically in the range of 0.003–0.34 g/tonne with average concentration of 0.14 g/tonne ( UNEP, 2014 ). However due to a large volume of coal burnt, a significant ...

Flue Gas - an overview ScienceDirect Topics

If CO 2 is to be separated, as much as 100 megawatts of a typical 500-megawatt coal-fired power plant would be necessary for today’s CO 2 capture processes based on the alkanolamines [4–6]. Therefore, it would be highly desirable if the flue gas mixtures can be used for CO 2 conversion but without pre-separation of CO 2.
