Claim 11:
12. A method for extracting a potable water from a raw water, the method comprising:
cooling, by a first heat exchanger, at least a portion of the raw water using liquid natural gas and converting at least a portion of the raw water into a pretreated raw water having ice water and a cryo-brine;
pre-heating, by the second heat exchanger, at least a portion of the pretreated raw water discharged by the first heat exchanger and converting the portion of the pretreated raw water into a warmed pretreated raw water;
heating, by a third heat exchanger, the warmed pretreated raw water discharged by the second heat exchanger by using a waste heat of a combined cycle power plant to convert the warmed pretreated raw water into a mixture of water vapors and hot pretreated water;
cooling, by a fourth heat exchanger, the mixture of water vapors and hot pretreated water by utilizing liquid natural gas and cool pretreated raw water from the first heat exchanger, wherein the water vapors are condensed into the potable water and the hot pretreated water is converted into a thermo-brine in response to the cooling of the mixture of water vapors and hot pretreated water; and
cooling, by the fifth heat exchanger, the thermo-brine and the cryo-brine by liquid natural gas, wherein the thermo-brine and the cryo-brine are converted into a saline ice and a dense brine in response to the cryo cooling of the thermo-brine and the cryo-brine.
