Ontario Hydro. A scrubbing process for flue gas desulfurization, based upon naturally occurring carbonate rocks, has been developed from laboratory to pilot plant scale. Calcitic limestones are better sulfur dioxide absorbents than dolomitic ones when used in the slurry form. The process was tested on a 200-cfm pilot plant on a coal-fired boiler.
