Reflux Ratio: The Formula Every Chemical Engineer Must Know

Reflux ratio is one of the most common questions asked in chemical engineering interviews, especially for process and plant engineering roles. In this quick explainer, we break down what reflux ratio actually means: the relationship between liquid returned to a distillation column and liquid withdrawn as product. You'll learn why a higher reflux ratio improves separation purity but increases energy cost at the reboiler, and how to explain this tradeoff clearly in an interview setting. This video is part of our ChemE Interview Prep series, built specifically for chemical engineering students and fresh graduates preparing for technical interviews at process, refining, and manufacturing companies. No fluff, no long lectures — just the exact concept, explained fast, so you can walk into your next interview prepared. Follow for daily videos covering distillation, heat exchangers, mass and energy balances, P&IDs, pump curves, and more core ChemE interview topics.
