Double Effect Evaporator Apparatus - Application: Heat Transfer Lab Equipments

Double Effect Evaporator 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.
Long tube evaporators are usually used for the concentration of foamy liquids.
The set-up is consists of two evaporators fitted in series. Each is made up of Stainless Steel tubes surrounded by a Stainless Steel jacket and fitted with accumulator.
Dilute solution is feed to the first evaporator.
Steam from a steam generator is supplied to evaporator 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 vapor s of volatile solvent produced in first evaporator are supplied to the second evaporator.
The vapor s of volatile solvent are condensed in a shell & tube type condenser and the balance non-volatile solute is collected in the accumulator.
