用Aspen property计算粘度，出现如下提示！！？ 方法1.重建这个模型，按楼上方法；方法2，做个简单过程来模拟。 计算倒是搞定的，但现在运行出现了问题，说是我的h2o和naoh组分都没定义，还说nrtl物性方法不适用。。。 - processing input specifications ... structure for component h2o has not been defined. pces cannot use group-contribution methods to estimate missing properties use the structures paragraph to define structures of this component. structure for component naoh has not been defined. pces cannot use group-contribution methods to estimate missing properties use the structures paragraph to define structures of this component. * warning in physical property system parameter dhvlwt/element 3 (data set 1) upper bound violated for component naoh value = 2.1002 , upper bound = 2.0000 * warning in physical property system parameter dhvlwt/element 4 (data set 1) lower bound violated for component naoh value = -5.1627 , lower bound = -2.0000 * warning in physical property system parameter plxant (data set 1) for component naoh: unreasonable vapor pressure calculated at normal boiling point. value should be within 10% of 1d5 n/sqm. please check your input for the antoine 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. - table generation begins ... - table generation completed 谢谢了。。。 查看更多
