Claim 0:
1. A desalination system for extracting a potable water from a raw water, the desalination system comprising:
a source of liquid natural gas;
a first heat exchanger adapted to receive the liquid natural gas from the source and facilitates a heat transfer between the liquid natural gas and the raw water to convert the raw water into a pretreated raw water having at least a minority of ice water and a cryo-brine;
a second heat exchanger arranged to heat at least a portion of the pretreated raw water exiting the first heat exchanger and converts the portion of pretreated raw water into a warmed pretreated raw water;
a third heat exchanger fluidly connected to the second heat exchanger and adapted to receive the warmed pretreated raw water discharged by the second heat exchanger to facilitate a heating of the warmed pretreated raw water to convert the warmed pretreated raw water into a mixture of water vapors and hot pretreated water;
a fourth heat exchanger configured to receive the liquid natural gas from the source and cool pretreated raw water discharged from the first heat exchanger and the mixture of water vapors and hot pretreated water from the third heat exchanger, wherein the fourth heat exchanger facilitates a heat transfer between the mixture of water vapors and hot pretreated water, cool pretreated raw water received from the first heat exchanger and the liquid natural gas to facilitate a condensation of the water vapors into the potable water and a conversion of the hot pretreated water into a thermo-brine; and
a fifth heat exchanger fluidly connected to the fourth heat exchanger and the first heat exchanger to, respectively, receive the thermo-brine and the cryo-brine, and forms a dense brine and a saline ice by cooling a mixture of the thermo-brine and the cryo-brine by the liquid natural gas received from the source.
