An older column is being used for a new process to separate an equimolar mixture of A and with a feed vapor fraction of 50%. The old column has 11 trays + a partial reboiler. The feed is between the 7th and 8th tray. The columns total condenser can achieve a reflux ratio of 1.75. What is the ideal feed location?
