WebThe non-equilibrium model was based on the two-film theory, and the effect of film discretization was examined. The equilibrium model was based on the theoretical number of stages combined with the concept of Murphree efficiency from 0.1 to 0.3 for three stages in the lower section of the column and 0.4 from stage 4 onwards. Webinfinitely large distillation tower would be required to distill to that composition of vapor and liquid. Further, if the equilibrium curve crosses the 45o line, the mixture has formed an azeo-trope. This means that even if the tower were infinitely large with an infinite amount of energy, it would be impossible to distill past that point by secret headquarters headphoneshttp://ww2.che.ufl.edu/ren/course/4404L/BD/BD%20Theory%20Handout.pdf secret headquarters imdb parents
