While each cement plant may differ in layout, equipment, and appearance, the general process of manufacturing portland cement is the same: crushed limestone and sand are mixed with ground clay, shale, iron ore, fly ash and alternative raw materials. Some manufacturers grind the raw materials dry, while others use a wet-grinding process ...
Altamira's first LNG plant is part of a wider project by New Fortress and Mexico's state-owned power utility CFE to build a $1.3 billion hub to convert U.S. and Mexican gas into LNG for export. Two additional floating LNG plants are under construction, with operations startup planned for 2025.
The basic chemistry of the cement manufacturing process begins with calcination, the decomposition of calcium carbonate (CaCO 3) at about 900 °C to leave calcium oxide (CaO, lime) and liberate gaseous carbon dioxide (CO 2).This is followed by the clinkering process in which the calcium oxide reacts at high temperature (typically …
Articles like this one can provide a lot of useful material. However, reading an article or two is perhaps not the best way to get a clear picture of a complex process like cement production.

2 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
Cement - Extraction, Processing, Manufacturing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary.

A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
The use of fossil fuels such as coal, natural gas, and oil is common in cement production, both as a fuel for the kiln and as a source of heat for other parts of the process which leads to CO2 emitted by combustion.However chemical reactions happening in the kiln (calcination) are also responsible for up to 60% of the total of emissions of the ...
