The Processes of Multi-effect Evaporation (ME) Salt Refinery
Multi-effect Evaporation has strong evaporation capacity, simple and stable operation, more energy and operating costs saving.
The multi-effect evaporation system is a series of evaporators connected in series, where the secondary steam from the previous effect is used as the heating steam for the next effect.
Except for the first effect, which uses fresh steam, all other effects utilize the secondary steam generated by the previous effect.
Only the secondary steam from the last effect requires a cooling medium for condensation.
Therefore, the multi-effect evaporation system not only significantly saves on the consumption of heating steam, but also significantly reduces the usage of cooling water.
Application
- Evaporation, concentration, and crystallization of aqueous solutions in the industries such as Salt Refinery, Nitrate Refinery, Food, Chemical Engineering, New Energy, etc.
- Be widely used in wastewater treatment in the above industries.
- Especially suitable for where the steam price relatively low.

The Processes of MVR Salt Refinery
MVR is mechanical vapor recompression, which is more energy and operating costs saving, small footprint, less public works, less total investment in the project, reliable operation and high degree of automation, and no need to add fresh steam during production.
In mechanical vapor recompression, the secondary steam evaporated from the evaporator is adiabatically compressed by a mechanically driven compressor, increasing its pressure and temperature.
Therefore, the compressor also functions as a heat pump to add energy to the steam. That is, during its working process, the low-grade steam is adiabatically compressed by the compressor, increasing its temperature, pressure, and enthalpy, and then enters the heating chamber of the evaporator to condense and release heat, fully utilizing the latent heat of the secondary steam.
Except for the initial startup, the entire evaporation process does not require fresh steam.
Application
- Evaporation and crystallization of materials with a wide range of evaporation capacity, heat sensitivity or high viscosity.
- Evaporation and crystallization of low-concentration wastewater that is prone to scaling.
- Especially suitable for where electricity prices are relatively cheap, while steam prices are is high price or supply is unstable.

The Processes of Mechanical Salt Refinery
Simple operation, stable running, much more energy saving, and different combinations of equipment and technological adjustments can produce salt in different sizes, purities and applications.
Salt washing, crushing and impurity extraction are defined as mechanical salt refinery. The main idea is to crush large salt particles to expose impurities as much as possible and wash out impurities from the particle surface.
Combined the technologies of screw washing, stirred washing, countercurrent washing and roller crushing, impurities could be washed out effectively while reducing salt powder and salt loss.
After crushing and washing, the drying system drys salt to the desired moisture content, and the sieving system classifies particles of different sizes for different applications (cooking salt, table salt, industrial salt, etc.).
The final product salt is dry, white, shiny, and free-flowing.
Application
- Producing salt with different particle sizes according to different needs.
- Making and ensuring even salt particle sizes for specific applications such as baking. Uniform salt particles guarantee consistent fermentation and texture control during the baking process.
