2. The following table specifies the separation to be achieved by means of a distillation column: The feed enters at its bubble-point temperature; vapour from the top tray enters a total condenser, the resulting liquid (distillate and reflux) leaves at its bubble point of 32 C. The reboiler operates at a temperature of 126C and the top tray temperature is 63C. The column operates at a pressure of 320kPa and pressure drops may be neglected. a) Identify the key components. b) Calculate the minimum reflux ratio. c) How many equilibrium stages would be needed to achieve this separation, if R= 1.1Riim and Niiai=6.44 d) How will Rmm and number of stages change if the feed is saturated vapor? Explain! No need to do any calculations 2.
