Open Pan Evaporator 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.

Learning Objectives/Experiments:
  • To determine the overall heat transfer co-efficient under unsteady state conditions at different temperatures
  • To determine the heat transfer co-efficient at the boiling point

Required for Operation:
  • Water Supply
  • Drain
  • Chemicals for experiments.
  • Special Arrangement To Measure the Evaporated Volume of Solvent is Done
  • The whole set-up is ingeniously designed and schematically arranged on a powder-coated rigid structure.

Technical 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 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 tubes surrounded 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.

Learning Objectives / Experiments:
  • 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

Plate Type Heat Exchanger consists of frame in which independent metal plates are clamped between a head and follower. The plates are sealed at their outer edges and around the ports by gaskets, which are so arranged that the liquid and the heating/cooling media are directed alternately into passages formed between the plates. The hot fluid enters at the top on the right side of the fixed end cover and flows downwards through alternate channels between the plates. The Hot fluid leaves the exchanger through a connection at the bottom of the fixed end cover. The cold fluid enters at the bottom of the left side of the fixed end cover. The cold fluid flows in counter current flow through alternate channels between the plates and leaves the exchanger at the top on the left side of the fixed end cover.
