Chemical engineering question can someone please help solve this

A binary mixture containing A and B is to be separated by continuous distillation. The mixture consists of 20 percent A and 80 percent B at the bubble point. The relative volatility of A to B is 3.0. The binary mixture is available at 100 kmol/hr and we wish to obtain a vapour distillate product that has a concentration of 95 percent A and that contains half of the component A in the feed stream.

(a) Calculate the liquid and vapour fraction (xA, yA) of component A used to plot the x-y plot.

(b) Evaluate if a (i) batch/differential distillation or a (ii) single-stage flash distillation is suitable to achieve the desired distillation. Justify your answer (with calculations if possible).

(c) If a fractional distillation with reflux is used, design a distillation column to achieve the desired distillation.

(d) An existing distillation column that is no longer being used is being considered for the distillation to save cost. The column is equipped with a partial condenser, a partial reboiler, and 6 plates above the reboiler. There are only two possible locations at which the feed can be introduced without any modifications to the column. These locations are plate 5, counting from the top, and directly into the reboiler. The reboiler is equipped with a steam coils capable of vaporising up to 85 kmol/hr of the liquid in the reboiler.
(i) Evaluate whether the column can be used to achieve the desired separation if the feed is introduced at plate 5 (may not be the optimum location) and the reflux ratio is set to 4.
Note: Make sure the reboiler have adequate capacity to generate enough vapour.
(ii) Estimate the lowest reflux ratio at which this column can be operated if the feed is
introduced at plate 5.
Note: Make sure the reboiler have adequate capacity to generate enough vapour.
(iii) Evaluate whether the column can be used to achieve the desired separation if the feed is introduced directly into the reboiler and the column is now operated at a reflux ratio of 4.
Note: Make sure the reboiler have adequate capacity to generate enough vapour.
(iv) Estimate the lowest reflux ratio at which this column can be operated if the feed is
introduced directly into the reboiler.
Note: Make sure the reboiler have adequate capacity to generate enough vapour.
