正丁醇和水共沸精馏模拟? 向大家请教个问题,还请不吝赐教: 现在做正丁醇和水的共沸精馏模拟,正丁醇质量含量0.784,水的质量含量为0.216,现用aspen dstwu精馏塔简捷计算,希望塔顶出料以共沸物的形式将完全水除去,塔釜出料全为正丁醇。但计算结果,显示 calculated minimum number of stages (-0.31783) is less than zero. this usually results when it is too easy to separate the light and heavy key components. 是什么原因,怎样解决?希望大家多多帮忙!非常感谢!!!!查看更多
