Answer :
Distillation column design involves obtaining equilibrium data, drawing operating and q-lines, stepping off stages for separation, and calculating reflux ratio. Column diameter and length require specific design calculations. Real designs may require computational methods and pilot data.
Resolving this question involves a complex combination of thermodynamics, heat transfer and fluid dynamics known as separation processes, particularly, distillation. In the present case, using the McCabe-Thiele method will help in finding the number of stages required for a desired separation of monochlorobenzene and dichlorobenzene.
First, the equilibrium data for the two components mixtures is organized in terms of relative volatilities. Second, an operating line that demonstrates the material balance around the entire column is drawn. Third, a q-line is plotted that represents the material balance around the feed stage. Where the operating line and q-line intersect is the feed stage.
The number of stages is determined by stepping off stages from the distillate composition to the bottom composition. The Reflux ratio is the ratio of the amount of liquid sent back down the column to that of product out. This can be determined by the intersection of operating and 45° lines.
Distillation column diameter and length would need specific design calculations, with input data like the mass flow rate, composition, the density of the liquid and vapor phases of the mixtures, and type of packing or trays used in the column.
This entire process simplifies the complex calculations involved in multi-component distillation design, but real accurate design may require computational methods and pilot plant data.
