Estimate the minimum number of ideal stages needed in the butane-pentane splitter defined by the compositions given
Question:
Estimate the minimum number of ideal stages needed in the butane-pentane splitter defined by the compositions given in the table below. The column will operate at a pressure of 8.3 bar. Evaluate the effect of changes in reflux ratio on the number of stages required. This is an example of the application of the Erbar-Maddox method. The feed is at its boiling point.
