Abstract: In this paper，the simulation and optimization of vinyl acetate distillation process was implemented by the flowsheeting simulation software. Compared with different thermodynamic models,we obtained the appropriate model and the optimal parameters of the feed-stage,reflux ratio and distillation ratio. In the case of the same tower，the vinyl acetate distillation strategy was modified by using the high efficiency flow-guided sieve tray. Running result of the revamped plant shows that the technology of high-efficiency distillation technology with computer optimization can improve the quility of the products and reduce the consumptions of raw metrials and energy. The economic benefits were considerable.
