Figure 5.14 Effect of total stages.

Figure 5.15d gives the results of the DISTIL analysis. The total number of stages is 30 with the feed introduced on stage 25. These results are in good agreement with the rigorous simulations. It should be noted that the results are very sensitive to the methyl acetate specification in the distillate. Figure 5.16 shows the ternary diagram with the stream points and the different sections of the column labeled.
