Cement Production an overview ScienceDirect Topics

Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

CCS from cement production Climate Technology Centre

CCS is a new technology, not yet proven at the industrial scale in cement production, but potentially promising. CO2 is captured as it is emitted, compressed to a liquid, then transported in pipelines to be permanently stored deep underground. Cement is a global commodity, manufactured at thousands of plants. The industry is consolidating globally, but large international firms account for
