PROCESS AND REAGENTS FOR THE REMOVAL OF MERCURY FROM COMBUSTION GASES

摘要

A method is provided for removing elemental mercury from a combustion gas by allowing the combustion gas to contact an aqueous dispersion or slurry (which can be a spray or aerosol) containing an alkaline-earth metal sulfide and a hyperdispersant or other surface- active agent, and preferably a phosphate and a pH buffer.
