A mixture of 1000 kg/h contains an equal parts by mass of methanol and water is distilled. Product streams leave the top and the bottom of the distillation column. The flow rate of the bottom stream is measured at 673kg/h and the overhead stream is analyzed and found to contain 96 wt % methanol. a. construct a flowchart of the process and perform the degree of freedom analysis. [6 marks] b' Determine the mass and mole fractions of methanol and water in the bottom product stream. [5 marks] calculate the rnolar flow rates of methanol and water in the bottom product stream. [5 marks] The bottom product stream is analyzed and the mole fraction of rnethanol is found to be significantly higher than the value calculated in part (b&c), state FOUR reasons for the discrepancy.
