Reflux condenser calculation

2017-01-04View Original

Thread Content

First, there is a reaction; dichloroethane is used as the solvent. The temperature is increased from 50 degrees to 90 degrees, and the mixture is allowed to reflux for 3 hours. How does one calculate the heat transfer in this case?

Does your reaction heat up? Heating + reaction heat~

Could you be more specific? Not quite sure

There is virtually no reaction heat; after the reaction is complete, the temperature is raised to 90 degrees and held there for 3 hours

That is, the reaction temperature is 50 degrees; after the reaction is complete, the temperature is raised to 90 degrees and the mixture is allowed to reflux for 3 hours. Since the boiling point of dichloroethane is around 85 degrees, I want to know how much vaporizes in order to calculate the heat exchange area required

Full reflux means condensing all of the vaporized steam, right? If there is no supercooling, and heat losses are ignored, then the amount of heat added is equal to the amount of heat removed

Yes, I want to know the amount of vaporization right now – the amount that occurs when the temperature is raised to 90 degrees and maintained at that level

If you measure the amount of condensate, that will roughly indicate the amount of vaporization
