A five-component mixture is to be distilled with 99 percent recovery of the light and heavy keys in the distillate and bottoms (Table 22.3). Calculate the product compositions for the case of infinite reflux. Explain how these concentrations would shift as the reflux ratio was decreased, using the compositions at minimum reflux as a guide.
