这个PROII模拟为什么检查通不过? 你的出错信息是指specification中的s5这个物流没有连到塔t2上,如果你用的是d版的8.0就很正常,是因为软件的问题,我以前经常碰到,后来用了8.1就好了。 我将你的问题在8.1版本里解了一下,将你的inp文件原封不动的导入,也有问题,是物性数据库的问题,库里缺少某些物质(如component 18 1m1ndene)的某些参数(liquid viscosity correlation ),而你定义的pure component properties 方法正需要这些参数: 2 error(s), 0 warning(s), and 0 message(s) detected: *** error *** liquid viscosity correlation data is required but missing for component 18. *** 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. 我把transport property methods 改为petroleum correlations就可以了,计算很正常,结果合理。看了一下这个体系,以烃和芳烃为主,用石油类传递数据是合理的。查看更多
