A liquid containing four components, A, B, C and D, with 0.3 mole fraction each of A, B and C, is to be continuously fractionated to give a top product of 0.9 mole fraction A and 0.1 mole fraction B. The bottoms are to contain not more than 0.05 mole fraction A.

(i) Determine the composition of distillate and bottom liquid stream

(ii) Determine the composition of the distillate and bottom liquid stream

(iii) Determine the minimum reflux ratio required for this separation, if the relative volatility of A to B is 2.0.

(iv) Estimate the number of theoretical stages needed for the separation (v) Determine the expression for the operating line for (i) above the feed plate (ii) below the feed plate
