Separation Process Question

Extracted text: 2) Fenske and estimation of a bottoms mole fraction. A column with 9 equilibrium stages and a partial reboiler is being operated at total reflux to separate a mixture of ethylene dibromide and propylene dibromide. Ethylene dibromide is more volatile, and the relative volatility (a) is constant at a value of 1.80. We are measuring a distillate concentration that is 98.4mol% ethylene dibromide. The column has a total condenser and saturated liquid reflux, and CMO can be assumed. Use the Fenske equation to predict the bottoms composition (xâ).
