Changing Relative Volatilities of Products

Now we consider the cases in which the relative volatilities between the two products and their adjacent reactants are different from the base case value of 2. Two cases are 

The second example is just the opposite. We have an easy separation between the heavy reactant and the heavy product. In this case, the relative volatilities are ac = 16, 

These results clearly indicate that the feed locations are important design parameters, and significant energy savings (ranging from 7% to 47%) will result if we place the
