Abstract


Determination of the number of theoretical stage in stagewise distillation is rather important for the design of a fractionator’s column. There are many graphical and empirical correlations for the determination of the theoretical stages, among these methods, is the graphical method of MCcabe-theile which is reliable.In a recent work by Gasmelsed G. A. etal it is approved that McCabe-Theile can be used for multi component fractionation, taking the light and heavy keys as pseudo binary. McCabe-Thiele method requires the condition of the feed, the equilibtuim data or relationship, the composition of the feed, top and bottom product mol fractions as well as the q – line. In this paper the number of theoretical stage were plotted manually by McCabe-Theile method and by software using MATLAB the result of the number of stage were compared and found to by in a agreement. It is recommended that MATLAB software program has to be extended for a complete design of the column.
