Description:
Calandria Evaporator
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. Long tube evaporators are usually used for the
concentration of foamy liquids. 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 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 accuI1mlator is recycled through
the evaporator
