ABE 413-EVAPORATION

Is an operation defined as the vaporization of a volatile solvent by ebullition to increase the concentration of essentially non-volatile components of a solution or suspension.

2. A type of evaporator where heat is supplied by condensation of steam in a jacket or in coils immersed in the liquid

  A type of evaporator where it is used for non-viscous liquids having high heat transfer coefficients and liquids that do not deposit scales.

A type of evaporator where it is not suitable for viscous liquid.

A type of evaporator where the liquid is inside the tubes is (3 -10 m long).

A type of evaporator where it is widely used for concentrating heat-sensitive materials such as fruit juices.

A type of evaporator where it is very suitable for viscous liquid.

A type of evaporator where it is suitable for highly viscous and heat-sensitive material- (e.g. rubber latex, gelatin, antibiotics and fruit juices)
