三元液液相平衡数据回归出错? 做《化工计算与软件应用》例题1-9时,按照题目做结果出错。提示如下: *** drs converged in 20 iterations, but constraints are not tightly converged *** * warning while executing drs case: "r-1" constraints not (tightly) satisfied for this case. ** error while executing drs case: "r-1" drs results do not agree with three-phase flash results. - rerun with a different set of parameter initial values - recheck the data in the data-group paragraphs - check std-dev for specifications that are too large ! data regression completed with errors 请高手指点! 查看更多
求教分馏塔进料过汽化量的定义方法? 呵呵,你在做常压蒸馏的例题吗?我两星期前刚做那个,我的工艺规定是columnt1 tray 17 liquid flowrate of all components on a wet basis in m3/hr/stream s1 flowrate of all components on a wet basis in m3/hr=0.03 。感觉是书有问题,应该是液化率为0.03才对,气化率为0.03的话塔不收敛。而且塔底部(第20块板)已经通入过热蒸汽帮助气化,不可能第17块板气化率那么低。看你也在学pro/ii,加我qq好友怎么样,一起学习共同提高,我也是自己在摸索着学。我的qq593263306查看更多
