Multi-Effect Evaporation (MEE) is a highly efficient thermal separation process used to concentrate liquids, typically water, by removing water through evaporation. The process involves multiple stages or “effects,” where steam produced in one effect is used as the heat source for the next effect, making the process energy-efficient. MEE is commonly used in industries where large volumes of liquid need to be evaporated, such as in wastewater treatment, desalination, and chemical processing.
In MEE, the liquid is heated in the first effect, and the resulting vapor is condensed. The condensed vapor from one effect is used to heat the next effect, where more liquid is evaporated. This cascading use of heat across multiple stages significantly reduces energy consumption compared to single-stage evaporation systems.
Types of MEE:
- Forward Feed MEE: Liquid flows from the first to the last effect in a continuous direction. Typically used when the feed liquid has a low concentration.
- Backward Feed MEE: The liquid enters the last effect and flows backward to the first effect, ideal for high-concentration feeds.
- Mixed Feed MEE: A combination of forward and backward feed systems used for varying concentrations and flow conditions.
