ABSTRACT:
This invention is directed to a method for scrubbing hazardous components from waste or flue gas in depleted or swept regions of a reservoir. In the practice of this invention, a waste gas is coinjected into a depleted or swept region along with an aqueous reactant. The swept or depleted regions serve as a reactor. The gas and an aqueous reactant in an amount sufficient to react with said gas is allowed to remain in the depleted or swept region for a time sufficient to react with said gas and remove harmful or hazardous components from the gas. Thus, harmful or hazardous components are scrubbed from the gas. When the scrubbed gas breaks through at another spaced apart site, a gas substantially devoid of harmful or hazardous components is produced to the surface.
