Evaporation Technology
Robust, simple and easy maintenance. Multi-Flash Evaporators with shell-and-tube heat exchangers.
The Multi-flash Evaporators, thanks to a combination of multiple effect pre-heater systems for heat recovery, followed by multi-stage flash evaporation; result advantageous for applications that involve large throughputs with a relatively low concentration factor -as in the Alumina industry.
For applications with low boiling point elevation, the Multi-flash Evaporators turn out to be quite cost-saving, both from an investment and operational point of view.
The liquid to be concentrated is heated in a series of heat exchangers and then routed into a cascade of flash vessels with a pressure gradient.
Upon entering a vessel, part of the liquid flashes into vapor while the remaining liquid is cooled down.
The produced vapor is used to heat the feed and/or discharge flow, depending on how the flash vessels and heat exchangers are arranged. The required heat input is provided by live steam from the first heat exchanger.
The liquid is fed to the vessel at the highest pressure and then flows to the next flash vessel by gravity.
Best suited for temperature-sensitive products and liquids with small amounts of solids and going up to high concentrations
Test facilities available for laboratory and pilot plant testing for different kinds of evaporator systems.
Skid mounted Falling Film and Forced Circulation Evaporators for small-scale production. Energy efficient, easy to transport and assemble.
For products insensitive to high temperatures, non-Newtonian products which allow a long residence time.
