摘　　要：针对PTA生产过程中副产物醋酸甲酯水解回收工艺,利用Aspen Plus软件进行厂级稳态流程模拟与集成优化设计。首先分析水解工艺的热力学、动力学性质,建立水解工艺稳态流程模拟结构,与实际生产数据对比分析验证稳态模拟结果的正确性;其次采用序贯优化法,以年生产成本最小化为目标,对工艺结构和操作参数进行优化,使工艺达到最佳操作条件且生产成本最低。For recovery process of methyl acetate hydrolysis, this paper simulated process and designed integrated optimization by using Aspen Plus software. Firstly, analyses of thermodynamic and kinetic properties of the hydrolysis process were given. Secondly, the paper established steady-state process simulation structure of hydrolysis process and verified the accuracy of steady-state results. Then it used sequential optimization method to optimize process structure and operation parameters at the aim of achieving minimum production cost. The results showed that operating condition was the best and production cost was the lowest after optimization.
