摘　　要：针对甲醇废水精馏进料中甲醇浓度变化对精馏操作过程的影响,采用PRO/II流程模拟计算软件对甲醇废水精馏过程进行模拟计算,考查了甲醇-水体系的相形为特点、塔顶和塔底的温度特性、塔内气液相负荷分布、回流比变化及对热负荷的影响,为生产操作提供理论指导依据。Aiming at the influence of the methanol concentration of in methanol distillation unit, the PRO/II simulation software was used for investigating the vapor-liquid phase characters, the temperature of the overhead and bottom of the distillation tower, the load distribution of the vapor, as well as the liquid, the variety of the reflux ratio and the heat duty of the tower.The obtained results provided the theoretical foundation for practical operation.
