Abstract
A process for removal of sulfur dioxide from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that reduces the amount of sulfur dioxide from the flue gas.

A process for reducing the amount of sulfur dioxide in a flue gas resulting from combustion of fossil fuel in a boiler comprising:
- (a) providing an alkaline admixture having a siloxane coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone;
- and
- (b) introducing the alkaline admixture to the boiler to create a reaction that reduces the amount of the pollutant in the flue gas.
A process for reducing the amount of sulfur dioxide from a flue gas resulting from combustion of fossil fuel comprising:
- (a) providing an alkaline admixture having a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone;
- and
- (b) adding the alkaline admixture to a fossil fuel feed within a combustion zone and thereby introducing the alkaline admixture to the boiler to create a reaction that reduces the amount of the sulfur dioxide in the flue gas.
