[PDF] Production and Application of Calcined Coke In Rotary …

Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical strength, and electrical conductivity …

Decarbonising the lime industry: State-of-the-art

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 …

Pyroprocessing and Kiln Operation

Kiln Operation Problems Using Pet Coke. The consequence of using pet coke is dusty conditions and a kiln inlet ring. Even though there is no CO (carbon monoxide) in the kiln inlet, the large amount of SO3 introduced by the pet coke may not be properly balanced by alkalis (Na2O and K2O) in the kiln feed.

CFD Modelling of Calcination in a Rotary Lime Kiln

A 2D axisymmetric computational fluid dynamics (CFD) model, coupled to a 1D bed model, has been developed to capture the key processes that occur within rotary lime kilns. The model simulates the calcination reaction using a shrinking core model, and predicts the start of calcination and the degree of calcination at the end of the kiln. The …
