MDEA再生模拟
MDEA再生模拟中遇到如下问题,请问如何解决那** WARNING **The liquid enthalpy of MDEA at temperature 313.15 K is outside
the acceptable range of 337.5 K through 506.25 K.
** WARNING **The liquid enthalpy of H2S at temperature 438.67 K is outside
the acceptable range of 187.68 K through 370 K.

一路上!! 2014/5/23 15:02:47
尤其是前2个警告
aspen求助建议上传源文件,然后说明aspen的版本 我用的是pro2 9.2的,源文件附上。请查阅 给我数据和流程我给你算试试 文件在3楼,去下来算吧 已收敛。
