Metabolism of metals from co-processing of energy-from ...

Co-processing of air pollution control residues (APCR) from energy-from-waste (EfW) facilities in the cement kiln is a potential alternative to landfill and an opportunity to reduce the virgin raw material demand of cement production. However, the high concentrations of trace metals and soluble salts in these residues are of concern.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

MERCURY IN THE CEMENT INDUSTRY

Mercury emissions are typically higher in kiln operations with the raw mill-off (“direct” operation) due to the missing adsorption capacity of the freshly ground particles in the raw mill. Periodic purging (bleeding) of cement kiln dust from the system is an efficient way to control and reduce mercury emissions.
