ASPEN中物性共沸参数如何设置? 用unifac估算出nrtl缺的二元交互参数后,在properties-parameters-binary interaction的nrtl-1中会出现所估算的二元交互参数。如果此时进行decanter倾析计算是可以的,但如果进行精馏模拟,会出现以下问题: *** severe error flash calculations failed to converge in maximum number of iterations. composite feed flash failed to converge; supply t-est, x-est and y-est as a workaround. 请问是不是所估算的参数进行精馏是不够的?需要估算其它的参数吗?望解答查看更多
