Distillation columns with sharp separations exhibit severely nonlinear behavior, which has been known to cause difficulties in column control and design. Such a column is characterized by sharp composition and temperature variations in the column. Pr

High-purity distillation columns are typically difficult to control because of their severely nonlinear behavior reflected by their sharp composition and temperature profiles. The dynamic behavior of such a column, as characterized by the movement of

We review the advancement of the dynamic theories based on wave propagation phenomena for two major classes of separation processes : fixed-bed sorption processes such as chromatography and countercurrent mass-transfer processes such as distillation.

A major difficulty in control of distillation columns stems from their nonlinear behavior, especially of columns producing high-purity products. Based on a previous development that adapted fixed-bed theories to simple countercurrent processes, this

To support the simple tools for steam stripping presented in part 1, part 2 here discusses the estimation of the infinite-dilution vapor-liquid equilibrium constants K∞ for organic pollutants in dilute aqueous solutions. A databank of K∞ at 1 atm

This study, presented in two articles, investigates the potential of steam stripping as a general at-source treatment of process water and wastewater for removing organic pollutants. Part 1 here presents stripping-factor-type equations for a primary

This paper complements the approximate dynamic model of multicomponent countercurrent mass-transfer processes presented in Part III based on an adaptation of the equilibrium coherence theory for fixed-bed sorption to countercurrent operation. The num
