In a copper recovery process, copper oxide (Cuo) reacts with ammonia (NH3) to produce copper (Cu), nitrogen (NG) and water (H,0). Feed 1 (650 mol) fed to the reactor contains 80 mol% Cuo and the balance impurities (1). Feed 2 contains 300 mol of pure NH3. At the end of the reaction, 337.5 mol Cu is recovered. The limiting reactant is not fully consumed in this process. (a) Write a balanced chemical equation for this reaction. (b) Draw and label the process flow diagram completely. (c) Identify the limiting and excess reactant and determine the percentage excess of the excess reactant. (d) Using Atomic Species Balance method, perform degree-of-freedom analysis, determine the amount (mol) of each component that exits the reactor outlet and the percentage conversion of the limiting reactant.
