Multi-flash evaporators for alumina industry

Processes Liquids for Efficient Heat Recovery and Concentration

The Multi-Flash Evaporators by GEA are engineered to streamline heat recovery and concentration processes across a variety of sectors, including alumina, chemical, and food industries. These systems leverage a multi-stage flash evaporation process, ensuring efficient handling of liquids with a low concentration factor. Operating continuously under gravity-fed conditions, they reduce scaling through non-heat exchanger evaporation, thus minimizing maintenance demands.

Strategically designed with shell-and-tube heat exchangers, these evaporators excel in reducing energy needs by maximizing heat recovery across multiple stages, with a capability comparable to a 13-stage system. Ideal for applications ranging from alumina hydrate production to concentrated fruit juices and caustic soda, they support large-scale operations with limited power consumption.

The evaporators are frequently used where low boiling point elevation is crucial, yielding significant cost savings. Constructed with robust materials, they maintain medium heat transfer coefficients, suitable for diverse operational conditions. Their design facilitates minimal cleaning interruptions, with an easy bypass for maintenance, enhancing overall operational efficiency. Customization options are available to align with specific industrial needs.
