which limestone, 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. However, some facilities recover a portion of the emissions- e.g. for use in sugar refining and precipitated calcium carbonate production.

This sodium carbonate is then pumped to a large vessel that holds slaked lime (Ca(OH)2). The two react to form caustic soda and calcium carbonate (CaCO3). The caustic soda is pumped off to once again mix with the wood chips, and the calcium carbonate is conveyed to a kiln where it is heated to convert it to lime (calcium oxide or CaO).

This conversion of calcium carbonate to calcium oxide is achieved by heating the limestone to a temperature high enough (e.g. 1000 C in a lime kiln) to 'drive off' carbon dioxide, CO 2. The equation for this process, with the approximate molecular weights, is: 100 CaCO 3 + Heat <==> 56 CaO + 44 CO 2 Continuing the approximation for hydration gives:
