Lime plants are responsible for the production of raw materials that are widely used in agriculture and the industrial sector. Lime-related products are obtained from the calcination of limestone —mainly calcium carbonate (CaCO 3)— at high temperature (900–1200 °C). The calcination reaction is highly endothermic; thus, a heat input is ...
