| 摘 要： | 利用PRO／Ⅱ软件对醋酸／水的萃取精馏进行了模拟。采用Hayden-O’Connell方程计算逸度系数，NRTL方程计算活度系数。模拟结果显示，与普通精馏相比，萃取精馏工艺的再沸器热负荷降低了51．8％，生产每吨醋酸耗费蒸汽量由8．9t降至4．6t，说明在同样的分离指标下，萃取精馏法分离醋酸／水要优于普通精馏法。

| Abstract: | Extractive distillation of acetic acid and water was simulated with the software PRO/II. To provide data for the simulation, the fugacity coefficients were calculated by Hayden-O'Connell equation, and the activity coefficients by NRTL equation. Simulation results showed that extractive distillation was superior to conventional distillation in separation of acetic acid and water, which heat duties of the reboilers was reduced by 51.8% , and the corresponding heating steam was reduced from 8.9 tons to 4.6 tons per ton acetic acid produced. |
