DoF analysis for distillation

Degree of Freedom analysis for a distillation column For students who have taken course on Degree of Freedom (DoF) analysis, this video links DoF to design calculations e.g. using McCabe-Thieles graphical method. NOTE In DoF analysis we simply rely on mass and energy being indestructible. The underlying assumption of linearity in DoF analysis is both correct and incorrect for non-linear systems such as distillation: Some solutions of the set of linear equations from a DoF analysis might be impossible to implement in a real system. At the same time, all possible results that can be achieved in a real system are also solutions to the linear set of equations (since matter and energy are indestructible).
