By using enrichment column, a top product of composition XD=0.90 was obtained. The feed composition was XF= 0.50 and molar flow rate was 100 kmol/h .It was determined that the reflux rate was 2 under the column operating conditions. The feed was fed to the column as a saturated liquid. According to this: a) Create the enriching section operating line equation using the given numerical data and show it on the equilibrium curve, b) Show the feed line on the equilibrium curve, c) Determine the ideal number of trays for the enriching section, d) Calculate the column efficiency if the actual number of trays in the enriching section is 10, e) Discuss how the ideal number of trays will be affected by changing the reflux ratio.
