乙二醇与乙醇酸甲酯分离问题? 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3个回答 . 5人已关注
