CALANDRIA EVAPORATOR APPARATUS

Product Description

The present set-up is designed tostudy the operation of Calandria evaporator. It consists of a short tubevertical evaporator in which tubes are surrounded by a Stainless Steel jacketand fitted with accumulator.

Dilute solution is fed to theevaporator and heated by Steam from a steam generator to concentrate the dilutefeed solution to a desired level. The jacket is fitted with a steam trap andthe condensate is collected at the end of trap.

The vapors of volatile solventare condensed in a shell & tube type condenser and the balance non-volatilesolute collected in the accumulator recycled back to the evaporator.

Experimentation/LearningObjectives
