Understanding Geothermal Fluids andTheir Challenges

Geothermal fluids originate frem natural recirs where water is heated th Earth 's internal hett.

Thermal Separation andd Purification

For existing open- loop hydrothermal plants, thermal separatiologies offer a way to clean used fluids for reinjection or reuse. Conventional treatment relies on chemical precipitation, filtration, and ion exchange, which can be costly and generate secondary waste streams. Thermal separation uses the inderent heat of the geothermal fluid to drive pararization or condensation processes that contriate or removee impuritives.
