Commissioning of a NaCl crystallization unit in a Peruvian mine

The commissioning of a NaCl crystallization unit has recently been carried out in a Peruvian mine, located in the middle of the Andean mountains, 3000m above sea level.

France Evaporation has successfully delivered, assembled and commissioned this unit of crystallization on a turnkey basis.

Among many other challenges, the following key targets have been met : volume reduction of highly corrosive salty waters from 36 ton/h down to 2 ton/h of salts produced in a solid form (crystals), while complying with quite severe conditions set by local Peruvian authorities in terms of allowable reject to environment.

This has been made possible by installing 3-stage of mechanical vapour recompression in series associated to 4 forced circulation evaporators, made of high grade materials.
