Working of Fractional Distillation Unit:
Fractional distillation is essentially a compact batch-type unit in which the reboiler consists of a vessel mounted in a heating bath and with a packed column above. The vapours from the top are condensed and can be refluxed as per requirement.
The top product is sub-cooled and collected in receivers. The bottom product is finally drained from the reboiler through a drain valve.
Fractional Distillation units are available in vessel sizes of 20,50,100 & 200L and is suitable for operation under atmospheric pressure and full vacuum.
