分离乙二醇与乙醇酸甲酯？ 用简捷计算dstwu模块 填写轻重组分时 按理说eg(乙二醇）沸点197高于mg沸点151 应为重组分但是无奈无法收敛 错误如下 block: adfd model: dstwu ** error calculated minimum number of stages (-13.960) is less than zero. this usually results when it is too easy to separate the light and heavy key components. ** error calculated feed location at tray -8.0647 is greater than the calculated mimimum number of stages (-13.960). ** error minimum reflux ratio calculated from underwood equation is -1.0408. reflux ratio reset to 0.1. *** severe error cannot solve gilliland equation for actual reflux ratio given the number of actual stages. 然后 我把eg作为轻组分 mg作为重组分再次运行 收敛 而且效果很好 但就是不符合轻重组分选择要求了 不知道这样操作是否可以？请各位看一下 大家讨论一下 ps：本人已上传bkp（rar格式，解压即可） 查看更多
