A simple distillation column is used to remove methanol from water. The input stream contains 43.5% by mass of methanol and the remainder water. The top product (vapour) stream contains 74.3% methanol by mass and the remainder water. The bottom product liquid) contains 28.6% methanol and the reminder water. i. Draw a flow chart for this process. (3 marks) ii. Conduct a degrees of freedom analysis, stating the number of unknown variables and total number of independent equations for this process. (2 marks) iii. If 538 kg/h of the vapour top product is produced, calculate the input mass flow rate and the mass flow rate of the bottom product in the process. (9 marks) If the density of the bottoms liquid stream is 0.960 g/mL, how many Litres (L) of bottoms product are produced per minute? (6 marks) iv. 1 AVAILABLE INFORMATION Density of water = 1 kg/L Quantity Equivalent Values Volume 1 m3 = 1000 L = 106 cm = 106 mL
