Q3: Acetone and ethanol are separated using a distillation column with a partial condenser and partial reboiler. An equimolar, sub-cooled liquid feed enters at 100 kmol/h and condenses Imole of vapor for every 6moles of feed. The separation requires a distillate vapor that is 95% acetone and bottoms liquid that is Smole %acetone. The reflux is returned from the condenser to the to the column as a saturated liquid and the operation is run at (L/V)=1.4×(L/V)min. Assume constant molar overflow conditions. Perform the following: A- Plot the operating lines for the rectifying and stripping sections and the feed line. B. Determine the number of equilibrium stages required and number of trays if each tray has an efficiency of 1. C-determine the optimal feed location.
