Problem 3. In class, we discussed the concept of reflux ratio, which is a key parameter in distillation design and operation. It turns out that distillation community sometimes use another parameter called the "boilup ratio" (Rp) to quantify distillation operation. The boilup ratio is defined as the ratio between boilup vapor flow rate and bottoms product flow rate. In other words: V RB B Starting from the mass balance equations, derive the relationship between the reflux ratio (R) and the boilup ratio (Ro) for a single-feed distillation column with saturated liquid feed
