11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.

The imperfectly calcined lime does not slake with water and is referred to as the dead-burnt lime. The lime stones should be broken into suitable sizes before they are burnt. For proper burning, fat lime stones should be broken into lumps of size 200 mm to 250 mm, and the hydraulic lime stones into lumps of size 75 mm to 100 mm.

The main application of PFR lime kilns is the production of high reactive, soft burnt lime. As the calcination process (CaCO 3 +heat @ T > 820 °C CaO+CO 2) consumes a large amount of heat, and most of the energy from fuel combustion is released at the upper end of the burning zone, the process temperatures in PFR lime kilns are relatively low.

The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …
