RECOVERY OF MERCURY CONTROL REAGENTS BY TRIBO-ELECTRIC SEPARATION

摘要

A method and apparatus for recovering mercury control reagents from particulate materials is disclosed. The particulate materials include fly ash mixed with mercury control reagents collected from boiler flue gases. The particulate materials are provided to an electrostatic separation system, which is operated under predetermined conditions so as to produce a concentrated stream of the mercury control reagent and a diluted stream containing minimal mercury control reagent.
