Commercial demonstration of the NOXSO SO sub 2 /NO sub x removal flue gas cleanup system: Comprehensive report to Congress: Clean Coal Technology program
This project proposed by MK-Ferguson will demonstrate the simultaneous removal of SO{sub x} and NO{sub x} from flue gas by a regenerable sorbent. It will also demonstrate the ability of the NOXSO process to destroy the evolved NO{sub x} and to recover elemental sulfur from the SO{sub 2} in the flue gas. In this project, the flue gas leaving the electrostatic precipitator (ESP) will be cooled by in-duct humidification and then routed to the fluid bed adsorbers, where SO{sub 2} and NO{sub x} will be adsorbed by the sorbent. The cleaned flue gas is then routed to the existing stack. The sorbent is continuously regenerated in a series of steps, each of which is carried out in a separate vessel. The NO{sub x} liberated by heating is returned with the combustion air to the boiler. The H{sub 2}S and SO{sub 2} are sent to a Claus plant where they react in the presence of a catalyst to form elemental sulfur -- a marketable by-product. The NOXSO process removes over 90% of the SO{sub 2} and up to 70% of the NO{sub x} from the incoming flue gas while generating no significant quantities of solid or liquid wastes. The project will be conducted at Ohio Edison's Niles Plant Unit 1, a 108 net megawatt electric (MWe) pulverized coal-fired cyclone boiler in Trumbull County, Ohio. This project scale will demonstrate the commercial applicability of the NOXSO process. 5 figs., 1 tab.
