What is the significance of External Reflux Ratio?

The external reflux ratio in distillation is a critical parameter that significantly influences the efficiency and effectiveness of the separation process.
The external reflux ratio plays a role in the energy efficiency of the distillation process. Higher reflux ratios generally require more energy input due to increased reboiler duty, but they can lead to better separation. Balancing the reflux ratio is crucial to achieving separation goals while minimizing energy consumption.
