the cold end of the kiln is the main gas moving fan. It pulls the combustion products, carbon dioxide from calcining, and the water vapor from the wet mud out of the cold end of the kiln. The ID fan is used to control the total air flow into the kiln for combustion, so controls the excess air or excess oxygen in the flue gas from the kiln.

Co-processing in cement manufacturing refers to the use of alternative fuels in both combustion and production processes. In terms of combustion, we're talking about substituting primary fuels, such as coal, petroleum and gas, with waste.

It is common practice to slightly under-displace the plug (usually by 1–3 bbl). This practice avoids control fluid flow back on the rig floor after placement and allows the plug to reach a hydrostatic balance. Once the plug is balanced, the pipe is slowly pulled out of the cement to a depth above the plug, and excess cement is reversed out.
CEMENT RAW MATERIALS - International Cement Review
Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes
