Aspen7.2间歇精馏运行报错 BLOCK B3 FAILED TO CONVERGE ...? 请教各位: 近来采用Aspen7.2做间歇精馏模拟,出现下列错误: SEVERE ERROR FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS. ** ERROR BLOCK B3 FAILED TO CONVERGE AFTER 0 ITERATION(S). *** SEVERE ERROR FLASH CALCULATIONS FAILED TO CONVERGE IN 11 ITERATIONS. BUBBLE POINT CALCULATION HAS DRIVEN THE TEMPERATURE DOWN TO THE LOWER LIMIT OF 78.9000 DEGREE K. BUBBLE POINT TEMPERATURE MAY NOT EXIST AT THE SPECIFIED PRESSURE. FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS. 小弟不知如何解决,请各位不吝赐教,万分感谢。。。。 查看更多1个回答 . 1人已关注
