This post was last edited by Refiner on 2017-1-15 10:20. I’m in the coking distillation tower and I see that a lot of the reflux involves internal reflux. For example, diesel. I haven’t seen this in catalysis. What considerations led to the design of internal recirculation?

Is it certain that all coking fractionation towers use internal recirculation?

Internal reflux provides the liquid phase for the lower trays, while external reflux helps remove excess heat from the tower
