SCHOOL OF CHEMICAL SCIENCES & ENGINEERING CEIC3001 Chemical Engineering Applications 2 Tutorial 5 Question 1 A saturated liquid mixture containing 30 mol% acetone and 70 mol% water is fed to a distillation column at a rate of 100 kg mol/hr. The condenser is operating as a total condenser and the system is operating at a reflux ratio of 2. The specification for the distillate is 93 mol% acetone while the bottom product must contain a minimum of 90 mol% water. The column is operating at a pressure of 1 atm. a) Construct the y - x diagram for the acetone/water system at 1 atm. b) Locate the point y 1 = x 0 = x D on the 45 ° line ( y = x line). The operating line for the enriching section of the column passes through this point. c) The slope of the operating line (enriching section) is L / V . Calculate this value and construct the operating line. d) What is the numerical value of the point at which the operating line intersects the y -axis? What is the significance of this point and how does it compare with the
