Minimum reflux

[thubelihle]

Hi,
Can l calculate boil up ratio from reflux ratio. I am following an aspen solution using reflux ratio and product purity as 2 specifications. The challenge in Coco is that l can't use these 2 specifications simultaneously as it requires both the distillate and bottoms specifications. So l decided to to conver reflux ratio to boil up ratio so that l use it as bottoms specifications. Was wondering that does this still fix the reflux ratio? Thanks

I do not have a direct answer to this. I suggest you use a parametric study to find out?
