Regarding the issue of the distillation column reflux liquid temperature
Thread Content
For an azeotropic distillation column with full reflux, where no requirements are placed on the quality of the overhead product and the reflux stream serves merely as an azeotrope, would an increase in the temperature of this reflux stream have a significant impact on the operation of the column?
Is this a problem with the design? Full reflux is of no use in actual production! An increase in temperature will definitely cause an increase in tower pressure!

An increase in the tower temperature leads to an increased gas-phase load, which is unfavorable for operation~~
It’s definitely not conducive to operation; I’m not sure how large the temperature changes are
It is actually beneficial for reducing steam consumption, provided that the quality requirements for the top product are not strict and it can be extracted casually
Yes, backflow is used to improve product purity as well as mass and heat transfer.
