What are the two processes experienced by the liquid that is being distilled? Under what condition does a liquid start boiling? (hint: think at the b.p. definition). How can be safely heated a flammable solvent to its boiling point.?
Homework Answers
The two processes that is being experienced by the liquid being distilled are:
Evaporation
Condensation
Evaporation is the process in which liquid sample is converted into vapour form. During distillation the liquid sample is heated to its boiling point when it reaches the boiling point it is condensed and collected separately.
Condensation is the process in which vapour is converted back to liquid again.
The liquid starts boiling when it's vapour pressure becomes equal to atmospheric pressure.
Flammable solvents are usually heated in steam or water bath.
Hope this helps you
Please provide feedback
Thanks

3. In a shell-and-tube heat exchanger, under nominal condition a process stream (a liquid) is heated from 100°C to 200°C without any phase change using a heating medium in the tube side, temperature of which gets reduced from 300°C to 150°C. The process side has a bypass which remains closed under nominal condition. Under nominal condition, there are equal resistances to heat transfer on shell and tube sides. It is desired that the process stream flowrate be increased by 30%,...
