Abstract

Energy demand of Bangladesh is rising continuously. Therefore, several power plants have been establishing, where the main fuel is a coal to satisfy this requirement. In Barapukuria, a coal-based power plant has already been activated to produce 250 MW electricity. 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 of environmental 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 concern here. Hence, this study is done to identify the adversity of this pollutant. For this reason, the amount of flue gas (SO2) is calculated which will help to understand the deviation from standard values. If any deviation is identified, mitigation steps should be taken to prevent the adversity. There are various methods to mitigate the flue gas (SO2), for example, wet scrubber, limestone/gypsum system, ammonia scrubbing, lime/limestone scrubbing for mitigation of sulfur dioxide (SO2). According to the suitability and efficiency of these processes, the best methods are explained to capture the flue gas (SO2) for saving our environment.
