Process to stabilize scrubber sludge
Patent
·
OSTI ID:7146336
A process for stabilizing sludge containing flyash and calcium sulfate formed by a lime or limestone scrubber increases the sludge particles to a size at which leaching of toxic metals from the particles no longer occurs at toxic levels. The sludge is dewatered and injected into the furnace in a manner to cause the flyash to soften and stick together. The agglomerated particles then fall into a bottom ash pit for removal as a common waste. 4 figs.
