Question

Evaluate the number of Theoretical Plates at total reflux required for the mixture to be fed to a continuous column, the mole fraction of ethane 0.06, propene (light key) is 0.2. Propane is 0.25, iso-butane is 0.41 and butane is 0.08. A product is required with a mole fraction of propene 0.025, Propane 0.95 and iso-butane 0.025. The relative volatility of propene to propane is 1.29 and propene to iso-butane is 1.1.
