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 is the ralatonship between internal and external reflux ratios?
The internal reflux ratio refers to the amount of liquid that is returned to the distillation column compared to the amount of vapor that is taken off as distillate, while the external reflux ratio is the ratio of the liquid returned to the distillation column to the liquid withdrawn as distillate from the system. A higher internal reflux ratio typically leads to improved separation efficiency, as it increases the contact time between vapor and liquid phases. The external reflux ratio, on the other hand, affects the overall operation of the distillation process and can influence the internal reflux ratio depending on the distillation design and operational conditions. Balancing both ratios is crucial for optimizing the separation process and achieving desired product purity.

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.
Why Reflux in distillation?
Reflux in distillation is the process of returning a portion of the condensed vapor back to the distillation column to enhance separation efficiency. This allows for improved contact between the vapor and liquid phases, facilitating the removal of impurities and achieving higher purity in the desired product. By controlling the reflux ratio, operators can optimize the balance between product yield and purity. Ultimately, reflux helps to better concentrate the components based on their boiling points.
