Can reflux ratio be less than 1
WebMay 5, 2024 · A reflux setup (Figure 1.58) allows for liquid to boil and condense, with the condensed liquid returning to the original flask. A reflux setup is analogous to a distillation, with the main difference being the vertical placement of the condenser. The liquid remains at the boiling point of the solvent (or solution) during active reflux.

For maximization problems, if the optimal solution is O ∗ and the worst possible approximate solution is O, then the standard way is to consider O ∗ / O as the approximation ratio. But in some text books, the ratio O / O ∗ is considered for both minimization and maximization problems and it causes the ratio to be smaller than 1.
