Title: Innovations of Sterling Gray in Flue Gas Desulfurization
Introduction
Sterling Gray is an accomplished inventor based in Louisville, KY (US), known for his significant contributions to the field of flue gas desulfurization. With a total of three patents to his name, Gray has developed innovative systems that enhance the efficiency and effectiveness of sulfur dioxide removal from flue gas.
Latest Patents
One of Gray's latest patents is focused on a "Clear liquor scrubbing magnesium-enhanced lime flue gas desulfurization" system. This improved system not only achieves high sulfur dioxide removal levels but also produces waste solids with better properties that are easier to dewater compared to those from existing systems. The system includes a crystallizer-clarifier reaction tank (CCRT) that processes scrubber effluent, functioning as both a reaction tank and a thickener. Clear liquor from the CCRT is utilized in a scrubber to treat flue gas, while thickened solids are directed to a high pH premix slurry tank (PMST) for controlled crystallization.
Another notable patent by Gray is the "Modification of magnesium-enhanced lime flue gas desulfurization process." This innovation enhances the wet magnesium-enhanced lime slurry process for sulfur dioxide removal. It incorporates the addition of process reagents to a separate premix slurry tank, maintaining a controlled high pH. The mixture is then circulated to a reaction tank, resulting in large crystal waste solids that are easily dewatered.
