Regarding the reflux ratio of the tower
Thread Content
I have a gentle question. As shown in the diagram, the reflux ratio for the stripping tower is given as 0.3. Is the reflux ratio (with respect to the feed) equal to the amount of reflux divided by the amount of feed? If the feed amount to the stripping tower is 10 tons, then the reflux amount should be around 3 tons, right? Am I understanding this correctly? Please share your thoughts, thank you
Yes, your understanding is correct. The reflux ratio is indeed the ratio of the amount of reflux to the amount of feed. If the stripping reflux ratio shown in the diagram is 0.3, then for a feed volume of 10 tons, the amount of reflux should be 3 tons. .
In the tower control scheme, there are controls for R/D (the conventional reflux ratio), as well as controls for R/F. For the design of distillation columns, more attention is paid to R/D.
Reflux ratio = reflux volume / product volume; the sum of the two equals the condensation volume at the tower top, which is determined based on the cooling load at the tower top
