This invention provides processes for reducing the environmental availability of one or more environmental pollutants in solids, liquids, and combinations of solids and liquids.

Processes for reducing environmental availability of environmental pollutants

This invention provides methods for reducing emissions of mercury from a cement plant comprising at least a kiln (), a particulate collection device (), collected particulates, an exhaust gas stream (), a heater, and a mercury scrubber, wherein the heater and mercury scrubber are upstream from the kiln. The methods comprise directing the collected particulates through the heater, to form volatilized mercury species from the collected particulates; directing the collected particulates from the heater downstream toward the kiln; and directing the volatilized mercury species to the mercury scrubber. The exhaust gas stream () exits the particulate collection device and is not directed into the heater. Optional steps include injecting a mercury sorbent at one or more points between the kiln and the particulate collection device.

Reduction of mercury emissions from cement plants

This invention provides a method for reducing mercury emissions from a cement plant comprising at least a particulate collection device and a preheater tower comprised of one or more preheater cyclones. The method comprises injecting pulverized coal into at least one preheater cyclone of said cement plant.
