CO CAPTURE IN THE CEMENT INDUSTRY

CO CAPTURE IN THE CEMENT INDUSTRY

The cement industry is one of the world’s largest industrial sources of CO2 emissions, accounting for 1.8 Gt/y in 2005, i.e. more than 6% of global emissions from the use of fossil fuels. Over the years the cement industry has substantially reduced emissions of CO2 per tonne of cement by improved energy efficiency, replacing fossil fuels with wastes which can sometimes be regarded as ...

Coal Usage in the Cement Industry - ausimm

Pulverised coal firing was pioneered in the cement industry prior to the turn of the century. Ash from the coal is absorbed into the mix in the kiln and replaces secondary materials. With high purity limestone coal with high ash content can be used. Fuel cost is a major part of the total manufacturing cost. Cement plants are thus quick to respond to fuel price changes and will use low grade ...

London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was ...
