Progress on Mathematic Models and Algorithms for the Steady-State Reactive Distillation Process

The reactive distillation that combines reaction and separation in the same vessel has achieved wide and quick development in recent years. This article describes the equilibrium stage model, non-equilibrium stage model and non-equilibrium stage cell model that are used in the steady-state simulation of the reactive distillation at length and summarizes the algorithms of each model. On the basis of analyzing and comparing these models and their algorithms, the future trends and advances are proposed.
