What is a reflux ratio?
Understand the Problem
The question is asking for the definition of a reflux ratio, which is a concept used in distillation and chemical engineering to describe the ratio of the liquid that returns to the distillation column vs. the liquid that is collected as distillate. It helps control the efficiency and separation of components in the distillation process.
Answer
The ratio of reflux to distillate in a distillation column.
The reflux ratio is the ratio of the liquid returned to the distillation column as reflux to the liquid product withdrawn as distillate.
Answer for screen readers
The reflux ratio is the ratio of the liquid returned to the distillation column as reflux to the liquid product withdrawn as distillate.
More Information
The reflux ratio is key to controlling the efficiency and separation capability of a distillation column. A higher reflux ratio often indicates better separation but also increased energy consumption.
Tips
A common mistake is confusing the reflux ratio with the distillate or take-off rate. Ensure that you focus on the ratio of returned reflux to removed distillate.
