New Correlation For Point Efficiency In Distillation Columns

One of the most commonly used simplifying assumptions in the mathematical modeling of distillation columns is the presumption of existence of ideal trays on which equilibrium of phases takes place. This is only realistically applicable if a precise method for the estimation of tray efficiency can be devised. The usually used tray efficiency evaluation schemes posses little accuracy and are therefore not recommended. This is due to the fact that each point location on each of the trays provides an opportunity for a mass transfer to take place, from which different components take different opportunities. So, in this paper; a new correlation for calculating point efficiency in distillation columns is obtained by Genetic Programming technique.
