摘      要：A method for order reduction of rigorous dynamic models of distillation columns is presented. The approach is a modification and extension of the compartmental models presented in 1986 by Benallou et al! Formulating the algebraic equations and the differential equations for total holdup for the compartments, but keeping the differential equations for concentration dynamics for each tray, Murphree tray efficiencies can be used and response accuracy increased. The resulting models of substantially lower order show good dynamic and steady-state conformity with the complete rigorous model. The example of an industrial binary distillation column *** the effectiveness of this approach.
