Abstract: "Insight into complex column heat flow facilitates extension of Underwood's method to columns with sidestream strippers and sidestream enrichers. This presentation is much simpler than previous ones. The same insights show that even though these configurations are more energy efficient, they require a larger temperature range for operation than analogous simple column sequences."
