|1. (WO2017197049) SULFITE PRECONDITIONING SYSTEMS AND METHODS TO REDUCE MERCURY CONCENTRATIONS IN WASTE WATER|
|Applicants:||GENERAL ELECTRIC COMPANY
|Inventors:||GANSLEY, Raymond, Raulfs
DALE, Trevor, James
|Title:||SULFITE PRECONDITIONING SYSTEMS AND METHODS TO REDUCE MERCURY CONCENTRATIONS IN WASTE WATER|
The present application provides a waste water preconditioning system for limiting mercury concentrations in a waste water stream resulting from treatment of a flue gas. The waste water preconditioning system may include a wet flue gas desulfurization system for treating the flue gas with an aqueous alkaline slurry, a sulfite detector to determine the concentration of sulfite in the aqueous alkaline slurry, and to produce the waste water stream with a mercury concentration of less than about five micrograms per liter. The waste water preconditioning system also may include a waste water treatment system downstream of the wet flue gas desulfurization system.
