CLIMBING FILM EVAPORATOR MP1050

MP1050

Main characteristics of the pilot

  • Industrial instrumentation

  • Flow switch of the condenser cooling water for operators safety

  • Borosilicate glass and stainless steel AISI 316L manufacturing

  • Rigid process pipes

  • Steam safety valve

  • Heating pipes insulation and protecting panels for operators safety

  • Atmospheric or vacuum process

 

PRINCIPLE OF WORKING :

The aim of evaporation is to concentrate a solution consisting of a volatile solvent and a non volatile solute. Climbing film evaporation is a continuous operation in which the solution is heated in a continuous jacketed stainless steel evaporator at high temperature. In the liquid – gas separator, the concentrate solution is collected and the vapour is evacuated, condensed and collected in the solvent receiver.


Teaching objectives

 

Study of the following parameters :

  • Continuous concentration of a solution using evaporation process.

  • Operating condition influences.

Calculation :

  • Thermal balance.

  • Mass balance.
