AI Technical Summary
⚠Technical Problem
The existing industrial equipment has low slurry consumption and auxiliary power utilization efficiency in flue gas desulfurization units, making it difficult to effectively control sulfur oxide emissions and meet regulatory requirements.
⚗Method used
A variable frequency drive motor and controller system is adopted, and sulfur oxide emissions are measured through a chimney sensor to optimize the operation of the slurry injector and booster fan, thereby reducing slurry and electricity consumption.
🎯Benefits of technology
This resulted in a reduction of approximately 33% in slurry consumption and up to 25% in auxiliary power savings, while ensuring that sulfur oxide emissions met legal limits.

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