请大家帮我看看怎么把回流比降下来
Minimum reflux ratio: 24.3329209Actual reflux ratio: 29.1995051
Minimum number of stages: 57.4367886
Number of actual stages: 104.516492
Feed stage: 54.6314982
Number of actual stages above feed: 53.6314982
Reboiler heating required: 5.0673573 Gcal/hr
Condenser cooling required: 5.00905573 Gcal/hr
Distillate temperature: 53.3546787 C
Bottom temperature: 94.0537431 C
Distillate to feed fraction: 0.10647695
具体得出来的数据就是这样的，最近在做ABB的苯乙烯分离原料中苯乙烯含量很大所以回流比降不下来，我们老师说不合理，其他论文也是7--9之间，但是我就是调不下去
