Air Pollution Control in the Cement Industry
Cement plants are now facing an increasing number of environmental regulations with tougher pollutants emission limits. Various polluting emissions such as particulates, SO2 SO3, NOx, HCl, HF, Hg and Dioxins/Furans can be released to the atmosphere during grinding and pyroprocessing operations.
To help its customers face these emission reductions, Fives designs and supplies high efficiency gas treatment systems to clean the exhaust gases throughout a cement plant. Fives’ equipment use the latest technologies in filtering to achieve the removal efficiencies required by customers in order to meet the most stringent environmental regulations.
Fives designs the right solutions for NOx emissions control and reduction combining primary and secondary technologies such as low NOx pyroprocessing technologies (burner, precalciners...) and selective reduction technologies (SCR, SNCR).
- Dedusting of process gas from cement main kiln/raw mill, coal mill, clinker cooler vent, finish mill
- Acid gas scrubbing and mercury abatement on main kiln
- NOx reduction on main cement kiln
