摘　　要：分析了四川维尼纶厂VAC和PVA两套生产装置的设计缺陷,并结合这两套独立运行的醋酸精馏系统的特点,将两套生产装置的醋酸精馏系统进行优化整合,同时优化这两套系统的运行方式,并采取措施充分地利用好VAC装置精馏塔出来的精醋酸的热能,从而达到了有效降低单位产品能耗的目的。Design defects of Sichuan Vinylon Works＇s vinyl acetate（VAC） and polyvinyl alcohol（PVA） production plants were analyzed.Their acetic acid distillation systems were optimized and integrated based on their features.Measures were also proposed to fully utilize the heat in the refined acetic acid from the distillation tower of the VAC plant.The above reformation effectively reduced energy consumption for production.

关 键 词：优化整合 醋酸精馏系统 VAC PVA 节能
