关于aspen plus中radfrac模型再生分离二氧化碳过程的问 ...? 各位高手,最近在用aspen模拟 氨水 吸收烟气中二氧化碳,之后再分离提纯的过程,其中分离提纯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: 2 3 4 5 A LIMIT OF 0.10000E-04 * SUM OF FEEDS WAS IMPOSED ON THE FLOW RATES. ** ERROR BLOCK B1 IS NOT IN MASS BALANCE: MASS INLET FLOW = 0.99653903E+03, MASS OUTLET FLOW = 0.10031541E+04 RELATIVE DIFFERENCE = 0.66380731E-02 我也试图通过改变进料的温度压力,以及 再生塔 中 再沸器 的负荷来检查错误,结果都不行,所以麻烦各位高人指点指点!如果有谁愿意也可以加我QQ819936844探讨探讨谢谢! 查看更多9个回答 . 1人已关注
