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 ï‚°C. The reboiler operates at a temperature of 126 ï‚°C and the top tray temperature is 63 ï‚°C. The column operates at a pressure of 320 kPa and pressure drops may be neglected.
a) Identify the key components.
b) Calculate the minimum reflux ratio.
