Oxy-fuel combustion technology for cement production ...

2016-2-1 · Cement production is one of the world's most energy and CO 2 intensive industrial production processes. In a recent report, emissions from this process were estimated to account for nearly 5% of the total anthropogenic CO 2 emissions (IEAGHG, 2013).Unlike in power plants, CO 2 is produced not only from the combustion of fossil fuels, but also from the calcination of raw meal (contains 70–80 ...

CO2 Emissions Profile of the U.S. Cement Industry

2015-9-10 · Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production.

Time to Decarbonize – Cement Americas

2021-10-21 · For example, fly-ash from coal combustion can partially replace clinker in cement. Less clinker production means reduced CO2 emissions. Binding CO2 into concrete during the curing process is also a way to utilize captured CO2. These concrete curing technologies will not be able to mitigate all the CO2 emissions from cement making.
