Shale Gas Produced Water
Concentration of produced water from unconventional gas production by hydraulic fracturing recovers clean condensate and high-quality, valuable sodium chloride and/or calcium chloride. Other compounds in the produced water are either removed upstream of the evaporation plant (heavy metals) or can be further concentrated for minimum liquid discharge.

Value
- Conversion of waste into saleable products (sodium chloride, calcium chloride, lithium, and bromine, among others)
- Design features minimize scaling and increase on-stream availability
- Use of energy efficient systems
- Plant operational flexibility allowing wide range of turn-down
- Liquid purge is minimized
- Smaller capacities can be processed by mobile units
- Process can handle high levels of contaminants

- Feed purification through chemical pre-treatment, such as elimination of scalents and heavy metals
- Filtration to remove precipitated heavy metals and other impurities
- Forced circulation evaporators used to handle suspended solids
- Centrifugation to separate sodium chloride
- Filtrate can be further concentrated to produce calcium chloride
