Impacts and Mitigation Approach of Flue Gas (SO2) in Coal Fired Power Plant of Bangladesh

Abstract

Energy demand of Bangladesh is rising continuously. Therefore, several power plants have been establishing, where the main fuel isa coal to satisfy this requirement. In Barapukuria, a coal-based power plant has already been activated to produce 250 MWelectricity. The coal-fired power plant in Matarbari (1200 MW), Payra Thermal Power Plant (1320 MW), Rampal Power Plant(1320MW) are under construction in addition to add 3840 MW. While boasting our power grid, it raises the concern ofenvironmental adversity that may occur by the emission of flue gases (SO2, NOx, CO2) and particulate material from the chimney.This exhaust emission causes a discrepancy in human health and the environment. Among these flue gases SO2 is prime concernhere. Hence, this study is done to identify the adversity of this pollutant. For this reason, the amount of flue gas (SO2) is calculatedwhich will help to understand the deviation from standard values. If any deviation is identified, mitigation steps should be taken toprevent the adversity. There are various methods to mitigate the flue gas (SO2), for example, wet scrubber, limestone/gypsumsystem, ammonia scrubbing, lime/limestone scrubbing for mitigation of sulfur dioxide (SO2). According to the suitability andefficiency of these processes, the best methods are explained to capture the flue gas (SO2) for saving our environment.
