What is the function of the condenser attached to the top of the reaction vessel? (As shown in the figure below), the vapor distilled from the reaction vessel is cooled by a condenser before being returned to the reaction vessel. What is the purpose of this process flow? Many reaction kettles have such a process
Remove heat to maintain reactant concentration and temperature
Reaction at atmospheric pressure, ensuring that the pressure inside the reactor remains at atmospheric level.
After a liquid material inside the tank reacts, a certain amount of steam is generated. To recover this liquid, this cooler is installed to condense the vaporized steam from the reaction mixture and return it to the reaction vessel to continue participating in the reaction. At the same time, it releases heat to balance the pressure inside the tank. To understand such problems, it is best to refer to the principles of chemical reactions as well as the physical and chemical properties of the materials before and after the reaction.
The operating temperature should be close to or equal to the boiling point of the material; it is necessary to condense and recycle the solvent, which is why this external reflux method is used； If only the solvent evaporation is to be reduced and the amount of evaporation is not significant, an internal recirculation method can also be used.
This should work on the same principle as internal recirculation.
The distillation tower has internal recirculation; is the internal recirculation in the reactor you mentioned similar?
