PDF Lime Production: Industry Profile

2.1.2 Calcination Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime

Pilot-scale calcination of limestone in steam-rich gas for direct

01/01 · In this work, calcination of limestone under steam-rich conditions simulating flue gas from a solid oxide fuel cell (SOFC), and subsequent ambient carbonation has been explored. Limestone was calcined under two steam concentration (21% and 35% vol) conditions in a 25 kW th pilot-scale bubbling fluidised bed (BFB), and then exposed to ambient air to evaluate DAC performance.
