Reaction Plants

Salt Plants NaCl.

High Purity Technical Salt also called Vacuum Salt is considered as a major feedstock to inorganic chlor-alkali industry.

3V TECH as a includes a raw brine treatment and make up level of sulphate and bivalent ions (Ca, Mg) to improve performance of saltwork. Optimizing technical salt purity, minimize purge, energy consumption, maintenance downtimes leading to extended refinery lifetime.  

3V TECH has ability to design and deliver various configuration of salt refineries using available source of energy: Mechanical Vapour Recompression (MVR) reducing carbon footprint and cooling water consumption, Multiple Effect Evaporation robust concept frequently utilizing steam produced by nearby cogeneration power plant, Thermal Vapour Recompression to improve steam economy.  

3V TECH has ability to work with depleted brine and to re-saturate it by means of Falling Film Evaporation. Or process sulfate rich reject into pure components: NaCl and Na2SO4.  

3V TECH and its environmental branch Greeneagle have ability to purify condensate up to RO quality. This makes 3V TECH very active in field of salty effluents focused to recover salts and water as reusable materials: Municipal Incineration Plants, Leaching of Incinerated Ashes, Cement Dust Leachate, Soda Ash Effluents, Produced Waters of High Salinity, Sulfate Rich Effluents from chloralkali plants etc.   

The global market of high grade salt is around 1.8 billion €/year.
