Carbon particulates up to three microns can be removed from flue gases. The process is to pass the polluted air through a duct where a solvent is sprayed across the flowing gas to lower than the saturation temperature at the pressure of the flue gas. Water can be used for most pollutans. Reactive fluids may be used to spray insoluble gases to precipitate the pollutants in the air. The suspended pollutants are dissoved into the spray as it is kept fluid at temperature lower than saturation. .
