ABSTRACT:
A pollution control system and method in which sulfur oxides in flue gases are adsorbed by activated char in a gas-solid contacting device. The saturated char is regenerated in an integrated desorption-reduction vessel, to which crushed coal and combustion-supporting air are supplied. A portion of the crushed coal is burned to provide the heat for the regeneration of the char, resulting in the formation of sulfur dioxide and carbon dioxide gases, and the chemical consumption of a portion of the char. The remaining crushed coal reduces the sulfur dioxide to gaseous sulfur, and results in a material having a porous system suitable for use in the adsorption of sulfur oxides. The remaining regenerated char and the oxidized coal are cycled back to the gas-solid contacting device, and the gaseous sulfur is condensed to liquid in a condenser.
