A $100k\frac{g}{h}$ ethanol$-$methanol stream is to be separated in a distillation column. The feed has $40\%$ ethanol, and the distillate has $90\%$ methanol. The flow rate of the bottom stream product is $40k\frac{g}{h}.$ Determine the percentage of methanol in the bottom stream. Perform degree of freedom analysis. Draw the diagram. Write the inlet and outlet flow rate values in different system of units. Suggest any other methods applicale to separate ethanol$-$methanol stream. How the ethanolmethanol stream is separated in distillation column?
