答:此错误为该模块的进料为零,原因为前几个模块中出现零物流输出,建议检查流程中没有物料的流股。若没有的话,设定撕裂流股,run- reconcile steam -tear steam
WARNING IN THE "STREAM" PARAGRAPH WHICH BEGINS ONLINE 45 STREAM NAME: 1 COMPONENT MASS FLOWS OF SUBSTREAM: "MIXED" ARENORMALIZED TO THE TOTAL MASS FLOW VALUE.
答:在定义“”(流股)的时候,原本应该是想按照或者来设置的,但是没有将“Composition”里默认的“Mole Flow”改为“Mole-Frac”或者“Mass-Frac”。改过来就好了!
ERROR
DESIGN SPEC IS NOT SATISFIED BECAUSE ONE OR MORE MANIPULATED VARIABLE IS AT ITS BOUND.
答:有可能按你设置的distillate RATE无法满足设计规定的目标值
两种情况:
1.设计规定设置的参数有问题导致内部迭代计算振荡发散无法收敛
2.塔规定的参数无法达到设计规定的目标值(由两物质的物质、塔操作参数决定) 建议:
在塔规定的参数下,采用灵敏度分析,这样就可以看出参数A对参数B的变化趋势
COMPONENT "YIXI" HAS ZERO FLOWRATE IN THE OUTLET STREAM.
FRACTIONALCONVERSION HAS BEEN MODIFIED BY A FACTOR OF "0.7407407"
答:你设定的转化率有问题,出口没流量,好像软件自己调整了,这应该是个警告,不是错误,可以根据需要自己调
Block: B1 Model: RADFRAC
***SEVERE ERROR
ALIQUID FEED/PUMPAROUND TO THE TOP STAGE IS REQUIRED WHEN
"Q1=0"IS SPECIFIED IN "COL-SPECS"; REQUIRED FEED/PUMPAROUND
HASZERO FLOW.
撕裂物流? 答:撕裂流是Aspen Plus给出其初始估值的一股物流,并且该估值在迭代过程中逐次更新,直到连续的两个估值在规定的容差范围内为止。
要规定一个撕裂流股
1. 在Data(数据)菜单中单击Convergence(收敛) 然后单击Tear(撕裂)
2. 在流股域中使用列表并选择一个流股标号
3. 此流股必须在模拟流程的一个循环回路中
4. 规定你选择的余下的任一可选域
检查一下你的第3项是否满足 WARNING
STREAMS CROSSING THE LOOP CONVERGED BY $OLVER02 ARE NOT IN MASS BALANCE: MASS INLET FLOW = 0.22021364E+00, MASS OUTLET FLOW = 0.22023670E+00 RELATIVE DIFFERENCE = 0.10470325E-03 IMBALANCE MAY BE DUE TO A LARGE RECYCLE FLOW, AND A
RELATIVELY LOOSE TEAR STREAM TOLERANCE.
答:调试就近分流器分流比。
