Improvements in Comparmental Modeling in Distillation

The compartmental modeling technique has recently been developed as a method to reduce the order of the dynamic model required to simulate staged separation processes. This paper identifies the critical specifications in the compartmental modeling approach in order to assure reasonable accuracy with sufficient savings in computational time when compared with the full order dynamic model. The importance of the algebraic structure (how the static material balance envelope is drawn) has not been reported by previous investigators.
