Abstract: In this paper, a generalized model of the reactive distillation processes was developed via
rate-based approach. The homotopy-continuation method was employed to solve the complicated
nonlinear model equations efficiently. The simulation on the reactive distillation
processes was carried out with the profiles of stage temperature,composition and flow rate
for both vapor and liquid phases obtained, Based on careful analysis of the simulation
results, the pitfalls in experimental design were detected. Finally, a software package for
the simulation of reactive distillation processes was developed.
