求助关于PROII RATEFRAC模块的问题? 求高手解答,首先,模拟时出现如下错误怎么解决:*** error *** unit 1, 't1' - volume and weight basis flow rates are only estimates for varied draws. enter the volume or weight basis rate for draw stream f3 as a specification, then vary the side draw rate to achieve it. 而后,求助哪位高手可以用proii ratefrac模块做一个常压塔的例子发给我啊?多谢大侠! 邮箱 478825113 查看更多
