Abstract: The systems and methods described herein integrate a supercritical fluid power generation system with a LNG production/NGL separation system. A heat exchanger thermally couples the supercritical fluid power generation system with the LNG production/NGL separation system. A relatively cool heat transfer medium, such as carbon dioxide, passes through the heat exchanger and cools a first portion of extracted natural gas. The relatively warm heat transfer medium returns to the supercritical fluid power generation system where a compressor and a thermal input device, such as a combustor, are used to increase the pressure and temperature of the heat transfer medium above its critical point to provide a supercritical heat transfer medium. A second portion of the extracted natural gas may be used as fuel for the thermal input device.

Abstract: A system reclaiming contaminated water includes a heat exchanger that receives the contaminated water and converts at least a portion of the contaminated water into steam and collects at least a portion of the contaminants within the heat exchanger. A thermal transfer fluid is heated by a heat exchanger is communication with a heat source. The heated fluid is circulated through the heat exchanger to heat the contaminated water. A steam engine is coupled to a generator, the steam engine receives the steam from the heat exchanger to drive the generator to provide power for the system. Steam exhausted from the steam engine is supplied to supplemental heat loads and then condensed in a modular condensing system. The collected contaminants are directed to an evaporation device to remove residual liquid.

Abstract: A system and method for providing dry cooling of a source liquid, having a plurality of heat exchangers which depolymerize and polymerize a polymer. Specifically, the depolymerization process is endothermic and draws heat from a source liquid in a first heat exchanger, and the polymerization process is exothermic and expels heat from a second heat exchanger. Additional heat exchangers and holding tanks may be incorporated in the system and method. In some embodiments the system further provides additional cooling of the polymer prior to depolymerization using cooler night ambient air.
