Calandria Evaporator

Product Description

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:

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