Direct separation/Indirect calcination

In a traditional cement plant, limestone is heated directly by the combustion of fuel in the calciner. This mixes the carbon dioxide (CO 2) released by the breakdown (or calcination) of the limestone (the process emissions) with the emissions that result from the combustion of the fuel. Direct separation differs in that it heats the limestone ...
