WebbThe number of steps between the operating lines and the equilibrium line represents the number of theoretical plates (or equilibrium stages) required for the distillation. For the binary distillation depicted in Figure 1, the required number of theoretical plates is 6. Constructing a McCabe–Thiele diagram is not always straightforward. WebbPlate number: The Plate number is a theoretical plate index (N) used to determine column efficiency. The plate number is arrived at by using the plate theory. Plate number changes depending on the type of analysis carried out. Tailing factor: This is also called as Symmetry factor.
