When can a serious problem arise with the Gilliland correlation?
Distillation is the separation process which is widely used in oil refineries. Distillation is the vapor-liquid separation technique in which the lower boiling components get separated by partial vaporizing the mixture of vapor and liquid.
Distillation is the both mass and energy transfer phenomena.
In multicomponent distillation more than two species are present in the feed.
The distillation column packed with the number of theoretical (equilibrium) stages upon which the mass and energy transfer take place to separate the liquid and vapor.
There are various methods are available to calculate the number of theoretical stages which is required for the desired degree of separation in multicomponent distillation.
Gilliland correlation is one of the most widely used method to calculate the number of theoretical stages in multicomponent distillation.
