Multi-Effective Evaporation technology is preferred due to its energy efficiency. The process is designed so that there is a pressure gradient across the entire evaporation system to allow the energy in the system to be reused.

In Multi-Effective Evaporation technology, the steam economy of the system varies linearly with the amount of effects used in the evaporation process design. Due to process limitations, multi-effects designs are typically limited to around 6 effects. The number of effects is limited by the total available temperature difference between plant steam and cooling water temperature. Solutions with high boiling point elevations typically operate with less efficiency.


  • Low steam usage
  • Suitable for many different types of evaporation
  • Simple and Flexible working
  • Ease of maintenance
