Calculating CO2 Emissions from the Production of Lime, Version 2

Lime is produced in a two or three step process: stone preparation, calcination, and hydration. Calcination is the process by which line, which is mostly calcium carbonate (CaCO. 3. ) is heated in a kiln to produce quick lime (CaO). Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere.
