DESCRIPTION:

Evaporation deals with the concentration of a non-volatile solute from a solution by the removal of required amount of volatile solvent. Usually the solvent is water. By vaporizing a part of the solvent, useful product i.e. the concentrated solution or thick liquor is produced and the vapour is discarded. It is a short tube vertical evaporator; the tubes are surrounded by a Stainless Steel jacket and fitted with accumulator. Dilute solution is feed to the evaporator and heated by Steam from a steam generator to concentrate the dilute feed solution to a desired level. The jacket is fitted with a steam trap and the condensate is collected at the end of trap. The vapours of volatile solvent are condensed in a shell & tube type condenser and the balance non-volatile solute collected in the accumulator is recycled through the evaporator.

EXPERIMENTATION:

To concentrate a solution and to evaluate the following at steady state:

1. Material and Heat Balance.
2. Economy and the capacity of the evaporator.
3. Overall heat transfer co-efficient.

UTILITIES REQUIRED:

•  Water Supply 5 lit/min (approx.)
•  Floor Drain.
•  Electricity Supply: 1 Phase, 220 V AC, 7 kW.
•  Required Chemicals.
