Multi-Effect Evaporation technology is among the evaporator systems preferred for energy efficiency. The process design combines a pressure gradient across the entire evaporator to allow the reuse of energy within the system. In Multi-Effect Evaporation technology, the steam economy of the system changes linearly with the number of effects used in the evaporation process design. Depending on process limitations, multi-effect designs are typically limited to around six effects. The number of effects is constrained by the total available temperature difference between plant steam and cooling water. Process solutions with high boiling point elevations typically operate with fewer effects.
Advantages:
- Low steam consumption
- Adaptable to many different types of evaporation
- Simple and flexible operation
- Ease of maintenance
