Study Notes

Definition and Process of Evaporation

  • Evaporation is defined as the removal of a solvent from a solution through vaporization aimed at concentrating the solution.
  • This process is employed to elevate the concentration of non-volatile dissolved or suspended components by removing parts of the liquid phase.
  • Energy for evaporation is typically supplied by a medium, facilitating the conversion of liquid to vapor.

Nature of Components

  • Dissolved or suspended components remain in the liquid and do not enter the vapor phase during evaporation.
  • If components do appear in the vapor phase, the process is classified as distillation.

Applications of Evaporation

  • Common applications include concentrating aqueous solutions of:
    • Sugar
    • Sodium chloride
    • Sodium hydroxide
    • Glycerol
    • Glue
    • Milk
    • Orange juice

Products of Evaporation

  • The main products resulting from evaporation can be either:
    • A more concentrated mixture remaining after solvent removal.
    • Overhead vapor which may be processed further or used as a valuable byproduct.
