Sodium carbonate monohydrate crystallizer

HPD sodium carbonate monohydrate crystallizer

HPD® Evaporation and Crystallization solutions from Veolia Water Technologies provides the soda ash industry complete process solutions for mechanically mined trona, synthetic production, and solution-mined deposits.This includes brine pre-treatment, brine stripping, sodium carbonate and sodium bicarbonate crystallization as well as purge recovery through the use of sodium carbonate decahydrate crystallization.

Unique Soda Ash Processes from Extensive Pilot Testing

Veolia's state of the art Evaporation and Crystallization Research and Development Center in Plainfield, Ill. is critical in the development and demonstration of complete process solutions to customers prior to a commitment on large capital expenditures.

Such developmental studies have involved core leaching, feed stock preparation, brine treatability studies as well as producing sodium carbonate and sodium bicarbonate material for use by the client in marketing to prospective to potential consumers and investors. The use of this facility has also been involved in many de-bottlenecking and optimization projects for existing facilities.

Applications and expertise include:

  • Pretreatment systems for solution-mined natural ores
  • Sodium carbonate monohydrate crystallization
  • Sodium bicarbonate crystallization (reactive and/or cooling)
  • Sodium carbonate purge minimization and alkali recovery
