Question

The process illustrated in the diagram is used to obtain calcium oxide (CaO) from calcite, a mineral that contains CaCO₃ and SiO₂. The reaction that happens in the oven is endothermic, which means that it requires heat. Said heat is provided by the combustion gases generated in the carbon burner. Consider the following simplifications of the problem and determine:
Assume that calcite is composed of 96% CaCO₃ and 4% SiO₂.
The air used in the burner is 300% in excess.
The composition of CO₂ in the final exhaust gases is 7.67% v
Both reactions have 100% conversion.
Consider that 120Kg of C. are supplied.
