Climbing Film Evaporator

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.
