PERFORMING A CEMENT PLANT OPERATIONS

The cement plants and process engineer (due to training and job title) is frequently asked to examine the “big picture” in a production/operations environment. This can be a formal request for a diagnostic review or a vague request from top management to see what’s wrong or what kind of improvements can be done with production/operations.

New approach suggests path to emissions-free

The process looks a bit like shaking a snow-globe, as it produces a flurry of suspended white particles inside the Limestone container as the lime precipitates out of the solution. While the technology is simple and could, in principle, be easily scaled up, a typical cement plant today produces about 700,000 tons of the material per year.

Cement Manufacturing: Ways to Reduce CO2

The primary source (60% of total emissions) is the calcination of limestone (CaCO3). Limestone, when heated to above 900 ºC, converts to quick lime (CaO), releasing CO2. The secondary source (40% of total emissions) is the burning of coal/fuel to provide the heat required for the calcination and clinkering process.

Cement manufacturing - components of a cement

After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.

Cement Production - an overview ScienceDirect

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).
