A 4-drum delayed coking unit in a petroleum refinery. A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke.
Roasting and calcination: In metallurgy, the process of heating a concentrated ore in the presence of oxygen is known as roasting. This process is applied in the case of sulfide ores. For ores containing carbonate or hydrated oxides, heating is done in the absence of air to melt the ores, and this process is known as calcination.
In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is. CaCO 3 (s) → CaO (s) + CO 2 (g) Today, this reaction largely occurs in a cement kiln . The standard Gibbs free energy of reaction is approximated as ΔG°r ≈ 177,100 − 158 T (J/mol).
