A method of desalinating an aqueous composition includes forming a hetero-azeotrope mixture by combining the aqueous composition with an entrainer, the aqueous composition including at least one salt, and subjecting the hetero-azeotrope mixture to distillation at a distillation temperature of less than the boiling temperature of the aqueous composition for an operating distillation pressure, resulting in separating the hetero-azeotrope mixture into a distillation bottoms liquid and a multi-phase condensate. The method includes recovering the multi-phase condensate having an entrainer-rich phase and an aqueous phase, the aqueous phase comprising desalinated water, and removing a portion of the aqueous phase from the multi-phase condensate to recover the desalinated water. Systems for conducting the method of desalinating an aqueous stream are also disclosed.

Systems and methods for generating liquid water include multiple atmospheric water generation devices adapted to produce liquid water from atmospheric humidity, during periods of off-peak power demand, and used in conjunction with a turbine. The turbine is usable to simultaneously provide power to the devices, while the air intake thereof is used to move air associated with the devices, enabling a generally continuous supply of atmospheric air to be processed while reducing the accumulation of heat associated with the devices.

A method is disclosed for recovering a useful gas from a gas mixture including a useful gas and at least one secondary gas. The gas mixture is first compressed and transferred into a pressure vessel where cooling occurs. Then, from the pressure vessel, a secondary-gas containing gas phase is removed and condensed useful gas is transferred into a purification vessel. In the purification vessel, the condensed useful gas is then purified. A plant is disclosed for recovering a useful gas from a gas mixture. Finally, the use of a plant for carrying out a method for recovering a useful gas from a gas mixture is disclosed.
