Q2 / Propane is separated from propylene by distillation . The compounds have close boiling points and the relative volatility will be low . For a feed composition of 15 per cent w / w propane , 90 per cent w / w propylene , estimate the number of theoretical plates needed to produce propylene overhead with a minimum purity of 98.5 mol per cent . The column will operate with a reflux ratio of 15. The feed will be at its boiling point . Take the relative volatility as constant at 1.1
