Simulation Design of Acetic Acid - Water

Azeotropic Distillation Process

Li Yanjuan, et al

(SinopecNingboEngineeringCompanyLimitedCo.,Ltd.ShanghaiBranch,Shanghai200030)

In this paper, acetic acid - water azeotropic distillation is calculated by using simulation software ASPEN PLUS. The NRTL-HOC thermodynamic model is used to calculate the azeotropic system, and the obtained gas-liquid equilibrium data at atmospheric pressure are compared with the literature, which is relatively consistent with the literature data. The residual curve of the ternary system of acetic acid - water - n-butyl acetate is simulated, and the distillation process simulation for this ternary heterogeneous azeotropic system is designed with the combination of the residual curve. The results show that under the studied feed conditions, the optimal operating parameters: the number of theoretical plates is 34; the main feed position at the fourteen theoretical plates; azeotropic agent using total reflux, water phase reflux ratio of 0.27 to 0.3.
