各位老马，小弟在做NaHCO3/Na2CO3吸收H2S的模拟，参考了aspen自带的K2CO3吸收H2S
的例子，但是在流程运行的时候总会出错，错误报告如下：
Block: B1 Model: RADFRAC
Convergence iterations:

2 1 1 0.18800E-10

*** SEVERE ERROR
MATERIAL AND ENERGY BALANCES FAILED TO CONVERGE: CHECK COL-SPECS
OR SUPPLY BETTER TEMPERATURE AND COMPOSITION ESTIMATES.

反而是我随便设置的进料条件下运行却能成功，但是一旦用了设定的条件运行就会报错，我
认为错误可能出在进料比例或进料量上，以前没怎么做过吸收塔，不晓得具体原因出在哪，
错误报告也不太能明白，还有，我已经在chemistry里设置了NaHCO3和Na2CO3的解离反应，
为什么运行结果吸收液中NaHCO3和Na2CO3仍然以分子形式存在的呢，这和错误有关系吗？
求指导。。小弟这厢多谢了！ps上传了两个附件，不知道哪个形式的能打开，版本是7.2的 |
