OPEN PAN EVAPORATOR

MAKE : CREATIVE LAB
MODEL NO: CLHT-28

DESCRIPTION:

Evaporation is a process for concentrating a solution by vaporizing part or all of the solvent. In most of the cases the solvent is water. The Pan Evaporator set-up is designed to study the fundamentals of evaporation process. The set-up consists of a jacketed pan evaporator made of stainless steel and an electrically heated steam generator of suitable capacity. To evaporate the solution in pan, steam is allowed to enter in the jacket using a control valve. Condensate is collected from steam trap for energy measurement. Tilting is done by a worm gear arrangement to empty the pan.

EXPERIMENTATION

SINGLE EFFECT EVAPORATOR

MAKE: CREATIVE LAB
MODEL NO:-CLHT-29

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. Long tube evaporators are usually used for the concentration of foamy liquids. The set-up consists of stainless steel tubessurrounded by a stainless steel jacket and fitted with accumulator. Dilute solution is feed to tubes. Steam from a steam generator is supplied to shell 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.
