Extracted text: 1. Lime (calcium oxide) is widely used in the production of cement, steel, medicines, insecticides, plant and animal food, soap, rubber, and many other familiar materials. It is usually produced by heating and decomposing limestone (CaCO ), a cheap and abundant mineral, in a process: CaCO3 (s) CaO(s) +CO2 (g) Limestone at 25 C is fed to a continuous calcination reactor. The calcination is complete, and the products leave at 900 C. Taking 1 metric ton (1000 kg) of limestone as a basis and elemental species [Ca(s), C(s), O (g)) at 25 C as references for enthalpy calculations, a) Sketch the flow diagram b) Prepare and fill in an inlet-outlet enthalpy table and calculate that the required heat transfer to the reactor.
