reflux ratio

is the ratio of the quantity of distilled material returns to the column to quantity of distillate.

One can operate the distillation column without calculating reflux ratio, but the main purpose of it is to improve the efficiency of the distillate.

What is the relation between internal and external reflux ratio in distillation column?

The internal reflux ratio is the ratio of the liquid returned as reflux to the distillate product inside the column, while the external reflux ratio is the ratio of the liquid refluxed back to the column to the distillate product taken out of the column. These ratios are related as the sum of the internal and external reflux ratios is equal to the total reflux ratio, which can affect the separation efficiency and energy consumption in a distillation column.


What is the optimum reflux ratio?

The optimum reflux ratio depends on the specific distillation process and desired outcomes. Generally, it is determined experimentally based on factors such as the desired purity of the distillate and energy efficiency. A higher reflux ratio typically results in higher purity but also requires more energy.


What is the relationship between Reflux Ratio and the number of contact stages?

The reflux ratio effects the positioning of the rectifying section operating line ( Xd/(Rmin+1) this equation gives the point at which the rectifying operating line intersects the y-axis ). therefore an infinte value for the reflux ratio will give the very minimum number of stages required. SO basically the relationship is, the higher the reflux ratio, the less stages needed. hope this answers your question.

What happens when the reflux is increased in a distillation column?

When more overhead liquid product is refluxed in a distillation column the liquid rate in the column increases. This may or may not be an optimal change in the column. Too little reflux will not have the proper vapor-liquid contact to promote separation and the overhead product will may meet the desired concentration specification. Too much reflux will flood the column and lead to wasted energy and cooling utilities associated with condensing more vapor than necessary. On a McCabe Thiele diagram for a binary distillation, increasing the reflux will decrease the slope of the stripping operating line. Typically the optimum reflux ratio (overhead product sent back to the column divided by distillate removed) is the theoretical minimum reflux ratio multiplied by a factor of 1.2-1.5.
