CO2 Capture in the Cement Industry - ScienceDirect

2009-02-01  In many ways the cement industry represents a good opportunity for CCS, because cement plants are relatively large point sources of CO 2 , the CO 2 concentration in cement plant flue gas is relatively high and over 60% of total CO 2 emissions from a modern cement plant are from mineral decomposition where the resulting CO 2 emissions cannot be avoided by use of alternative energy

Cement kiln - Wikipedia

PAHs (according to EPA 610) in the exhaust gas of rotary kilns usually appear at a distribution dominated by naphthalene, which accounts for a share of more than 90% by mass. The rotary kiln systems of the cement industry destroy virtually completely the PAHs input via fuels. Emissions are generated from organic constituents in the raw material.
