Indian coal contains sulphur in the range of 0.2 per cent to 0.7 per cent by weight. With this sulphur content, it is estimated that domestic coal-based plants emit Sulphur Dioxide (SO2) in the range of 800-1,600 mg/Nm3. This is beyond the range specified in the emission norms of flue gas set by the Ministry of Environment, Forest and Climate Change (MoEFCC) to achieve desulfurization in India as specified by govt in 7th December 2015. All public/private companies and government organizations are, therefore, retrofitting thermal power plant (TPP) units with SOx-control technologies using flue gas desulfurization techniques. One of the most widely used technologies for Sulphur Oxide (SOx) control is wet flue gas desulphurization (FGD) based on limestone. Under this post-combustion SOx elimination method, SOx is passed through a bed of lime or limestone and is oxidized to form gypsum, which can then be eliminated as a byproduct. Apart from limestone, seawater and ammonia can be used in wet flue gas desulfurization (FGD) as reagents. This study aims at knowing the suitable technique of SOx removal from the flue gas emitting from coal combustion of 250 MW thermal power plant.
