Methanol is produced by reacting CO with H2. A portion of the methanol leaving the reaction cell is stopped. The unreacted portion of CO and H2 along with the non-condensable methanol is returned to the reaction cell. The total flow of substances out of the reaction cell is 275 mol/min and contains: 0.227 H2; 0.330 CO; 0.443 methanol (molar fraction). The mole fraction of methanol in the circulating stream is 0.004. a. Perform a degree of freedom analysis and calculate the molar flow rate of CO and H2 at the initial input stream, and the molar mass of the methanol product (methanol condensate).b. After several months of operation, the flow of liquid methanol leaving the cooler began to decrease. List three hypotheses that cause this phenomenon and how to test them. (hint: test is the method used to test the hypothesis).
