A rigorous algorithm has been developed for the unsteady-state simulation of multicomponent, adiabatic absorption in packed columns. The simulation uses an implicit integration scheme to solve the partial differential model equations which may include both nonideal vapor-liquid equilibrium relationships and nonlinear mass-transfer expressions. All physical parameters used in the model are obtained from empirical correlations available in the literature. Simulation predictions, both dynamic and final steady-state, compared favorably with experimental results.The numerical simulation of continuous-contact separation devices is a topic that has long been neglected. In a previous article (Hitch et al., 1986), we pointed out that until recently most research efforts in the area of the design and analysis of separation processes have concentrated on
