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.

A process is carried out in which a mixture containing 25.0 wt% methanol, 42.5% ethanol, and the balance water is separated into two fractions. A technician draws and analyzes samples of both product streams and reports that one stream contains 39.8% methanol and 31.5% ethanol and the other contains 19.7% methanol and 41.2% ethanol. You examine the reported figures and tell the technician that they must be wrong and that stream analyses should be carried out again. Is your statement...

Consider the distillation of a saturated liquid feed of 0.16 mol fraction methanol and 0.84 mol fraction water. The column has a side stream of composition 0.5 mol fraction methanol and a flow rate of 7.7% of the feed rate. The top product is to contain 0.77 mol fraction methanol and the bottom product is to contain 0.02 mol fraction methanol. The column operates at 1 atm, and the usual simplifying assumptions can be made. The external reflux ratio is...
