Consider the equilibrium data for methanol-water system at $1$ bar given in the future below.
A distillation column operating at $1.0$ bar is required to produce $92 \: mol \: \%$ methanol. The feed is a saturated liquid. It is an equimolar mixture of methanol and water. The minimum reflux ratio is
- $0.33$
- $0.50$
- $0.54$
- $1.17$
