Patent ID: 10617973

Abstract:
Embodiments of the present invention are directed to a cryo-thermal desalinator, which addresses thermal desalination inefficiency by introducing intrinsic cooling potentials of strategically-piped liquidized gasses to save fuel and increase potable water output. Liquid natural gas fuel flows through internally routed, uninsulated and dedicated piping to natural gas brine burners located outside and under a vessel. The liquid natural gas fuel contributes to condensation and converts to eventual pre-warmed natural gas at the brine burners. Liquid gas flows through an internally routed, closed-loop piping to continually provide condensation, while a liquid gas compressor of the closed-loop exhausts waste heat to assist brine conversion. Saline water piping inside the vessel implements cooling via an optional alternative cooling heat exchanger, accepting portable liquid nitrogen, liquid CO2 dry ice, or both. The cryo-thermal desalinator's multi-cooling liquid gas systems accommodate multi-thermal inputs, assisting with unfired production of thermal desalination water vapor in real time.
