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
