ASPEN能模拟无机盐吗? 感觉熔盐这一侧就不用管了,按另一侧的物系选热力学方法。 谢谢6119 因熔盐是个混合物,不能像纯组分那样输入粘度比热这些性质吧?既然aspen上有这三种盐类的物性,为什么软件自身不能模拟还要自己输入啊? 另外,换热器另一侧是导热油(二苄基甲苯异构体),因数据库中没有,手动输入分子结构,饱和蒸汽压,比热等参数,物性方法选择了bk10(虽然导热油也没有相变化,但是别的也不知道选什么方法),但是结果怎么提醒 * warning in physical property system parameter cpig (data set 1) for component 26989-17: unreasonable heat capacity calculated at temperature lower bound, value = 1474.5 j/kmol-k. value should be greater than minimum allowable value = 8314.3 j/kmol-k. please check your input for the cpig parameters. * warning in physical property system nrtl binary parameters for all component pairs are zero, your results may not be accurate. please review and provide binary parameters as appropriate. flowsheet analysis : computation order for the flowsheet: b1 - calculations begin ... vapor pressure model pl0xant has missing parameters: plxant/1st element (data set 1) missing for component 26989-17 ****property parameter error errors encountered in calculation of vapor-liquid k-values using option set bk10 for kvl 查看更多
