Abstract
A method (200) for desulfurization of a flue gas in a desulfurization unit of an industrial plant, includes receiving (202) a plurality of baseline parameters corresponding to the desulfurization unit of the industrial plant. The method further includes measuring (204), using a stack sensor, an emission value of sulfur oxides in the flue gas. The method also includes estimating (208), using a controller, a desirable value of a slurry parameter for desulfurization of the flue gas based on the measured emission value of the sulfur oxides. The method further includes determining (208), using the controller, at least one desulfurization parameter based on the desirable value of the slurry parameter. The method also includes controlling (210), using the controller, operation of the desulfurization unit based on the at least one desulfurization parameter to modify consumption of at least one of a slurry and an auxiliary power in the industrial plant.
