求助Aspen模拟mdea不收敛,而且吸收效果不对? ** ERROR RADFRAC NOT CONVERGED IN 25 OUTSIDE LOOP ITERATIONS. *** SEVERE ERROR MATERIAL AND ENERGY BALANCES FAILED TO CONVERGE: CHECK COL-SPECS OR SUPPLY BETTER TEMPERATURE AND COMPOSITION ESTIMATES. ** ERROR BLOCK B9 IS NOT IN MASS BALANCE: MASS INLET FLOW = 0.31180225E+02, MASS OUTLET FLOW = 0.31490651E+02 RELATIVE DIFFERENCE = 0.99558725E-02 ->Simulation calculations completed ... 如果稍微改变回流量R(如改为70kmol/h),运行不能收敛,调了好久了,请哪位大虾,大侠帮一下忙。看看是什么问题,不胜感激!!查看更多22个回答 . 3人已关注
