Aspen plus中radfrac模型模拟MEA脱碳的问题

lin2232337036

各位高手，我在用aspen模拟MEA脱碳过程，其中Radfrac模块总是出现以下三个错误：
SEVERE ERROR
   MATERIAL AND ENERGY BALANCES FAILED TO CONVERGE: CHECK COL-SPECS
   OR SUPPLY BETTER TEMPERATURE AND COMPOSITION ESTIMATES.

***SEVERE ERROR
   THE FOLLOWING STAGES DRIED UP:
     8    9   10
   A LIMIT OF  0.10000E-04 * SUM OF FEEDS WAS IMPOSED ON THE FLOW RATES.

** ERROR
   BLOCK DESORBER IS NOT IN MASS BALANCE:
   MASS INLET FLOW = 0.78967885E+04, MASS OUTLET FLOW = 0.79592454E+04
   RELATIVE DIFFERENCE = 0.79091463E-02
更为神奇的是，吸收和再生过程分别模拟时就没有错，一旦二者合起来就报错，死活解决不了，麻烦各位救救在科研路上挣扎的打工人吧，有谁愿意的话也可以加我微信lin2232337036仔细探讨。谢谢大家了
