The process examined is a typical calcination process. In this analysis, limestone is first calcinated. The product reacts with water producing calcium hydroxide, which is further carbonated with carbon dioxide from calcination to produce PCC. The report examines one-time costs associated with the construction of a plant and the continuing costs

Calcination is an endothermic reaction that begins to take place at approximately 875°C. Typically, rotary kilns are used for this process. These kilns are typically operated at 1100°C or more in order to allow for consistent yields of CaO. The primary aim of this thesis was to generate a model of the calcination process in a rotary kiln to ...
