热力学方法问题吗? 请教各位了,我在算NF3的精馏,选择的是SRKH方程,可是计算的时候总是出现如下错误: *** error *** Component 4, supplied on the libid statement, has no default phase stored in the library. Please use a phase statement to assign one. *** error *** Liquid viscosity correlation data is required but missing for component 8. *** error *** Transport property methods requiring certain pure component properties are specified, but those properties are not available for some components as listed above. Transport properties are only required for certain transport calculations such as column hydraulics, rate based distillation, rigorous heat exchangers and pipe unit operations. You may turn off transport calculations for this simulation if they are not being used. 然后我把热力学方法中transport properties中的小对号勾掉了,运行,又出现如下错误: *** error *** Component 4, supplied on the libid statement, has no default phase stored in the library. Please use a phase statement to assign one. 其中所说的component 4就是NF3,是说library里没有默认的相态吗?可是看组分里默认的是vapor-liquid啊? 希望高手指点,多谢了!查看更多2个回答 . 5人已关注
请朋友帮助翻译下面的语句? The reboiler chest pressure was adjusted to obtain normal reboiler duty. This emulates pressure drop across the steam control valve at steady-state conditions.查看更多4个回答 . 5人已关注
