Distillation reflux issue
Thread Content
I have a question for everyone. When designing the system, I added a blind flange to the return pipe from the condenser to the reactor, as I thought that in the case of simple distillation, the condensed liquid wouldn’t flow back. However, my supervisor asked me to remove that blind flange. I would like to know when the condensed liquid will flow back into the reactor
There’s no reason to install blind flanges at all. Generally, reflux takes place continuously; if blind flanges are used, how can reflux occur back into the reactor?

Under normal operating conditions, internal recirculation can be used to reduce solvent evaporation losses.
For example, there is backflow dehydration (separation of oil and water, removal of water), with the solvent continuing to flow into the reactor, etc
