Method of removing gaseous pollutants from flue gas

Patent ·
OSTI ID:6458392
;
A spray dryer apparatus is used to bring a water solution or slurry of finely-divided, basic reactant into intimate contact with a flue gas bearing acidic gases or vapors. The basic material reacts with the acids in the flue gas to form a particulate precipitate, while the water from the solution or slurry is fully evaporated in the gas stream. Conventional means are then utilized to remove the particulate reaction product from the flowing gas stream.
