Abstract:
The invention relates to a method for operating an osmotic power plant. A first solution (3) with a first concentration of at least one substance (20), which can be dissolved in a solvent of the first solution (3), and a second solution (4) are provided. The second solution (4) has a second lower concentration of the at least one substance (20). At least the first solution (3) is provided by means of at least one thermal separating device (12). In the at least one thermal separating device (12), a starting solution (18) which contains the at least one substance (20) is introduced into an evaporator (17), through which a gaseous medium flows. The at least one substance (20) is discharged out of the evaporator (17) by means of the gaseous medium. The at least one substance (20) which is discharged in the gaseous medium is converted into a liquid phase in a condenser (22) of the at least one thermal separating device (12) in order to provide the first solution (3). In the starting solution (18), a substance which can be more easily converted into the gas phase than the solvent of the starting solution (18) is used as the at least one substance (20). The invention further relates to an osmotic power plant.
Abstract:
Methods, systems, and/or apparatuses (5) for treating wastewater produced at a thermoelectric power plant, other industrial plants, and/or other industrial sources are disclosed. The wastewater (16) is directed through a wastewater concentrator (5) including a direct contact adiabatic concentration system. A stream of hot feed gases is directed (104) through the wastewater concentrator. The wastewater concentrator mixes the hot feed gases directly with the wastewater and evaporates water vapor from the wastewater. The wastewater concentrator separates (A) the water vapor from remaining concentrated wastewater. A contained air-water interface liquid evaporator may be arranged to pre-process the wastewater before being treated by the wastewater concentrator.

Abstract:
The method includes an atomization step, and a separation step. A solution L is atomized into mist in air whereby producing mist-mixed air in the atomization step. Droplets of the mist included in the mist-mixed air are classified according to their particle diameter sizes, and exhaust air that contains air as carrier gas is exhausted in the separation step. In the atomizing separation method, the heat energy of both of the latent heat and sensible heat that are included in the exhaust air exhausted in the separation step are collected, and one or both of the solution L to be atomized in the atomization step and air to be blown toward the solution L are heated by the collected heat.
Abstract:
A feed liquid flows into a second-stage humidifier chamber to form a second-stage humidifier bath. A first remnant of the feed liquid from the second-stage humidifier chamber then flows into a first-stage humidifier chamber to form a first-stage humidifier bath having a temperature lower than that of the second-stage bath. A second remnant of the feed liquid is then removed from the first-stage humidifier. Meanwhile, a carrier gas is injected into and bubbled through the first-stage humidifier bath, collecting a vaporizable component in vapor form from the first remnant of the feed liquid to partially humidify the carrier gas. The partially humidified carrier gas is then bubbled through the second-stage humidifier bath, where the carrier gas collects more of the vaporizable component in vapor form from the feed liquid to further humidify the carrier gas before the humidified carrier gas is removed from the second-stage humidifier chamber.
Abstract:
A process of mass transfer is described which utilises latent heat transfer with little or sensible heat transfer. In a preferred process microbubbles are used under certain conditions of contact with a liquid phase to ensure highly effective mass transfer between a gaseous and liquid phase with significantly less than expected or little or no sensible heat transfer. The present invention in part provides a means by which the known state of a cold liquid of varying depths can be changed using a hot gas injected via a micro bubble inducing internal mixing without allowing the resultant mixture to reach equilibrium thereby ensuring the transfer process becomes continuous. Thus a process is described wherein at least one gaseous phase is contacted with at least one liquid phase such that the heat ratio of the system (AA) is maintained at an a value of greater than 0.5, and the mass transfer is effected by passing a gaseous phase comprising microbubbles through a liquid phase of thickness no more than 10 cm.
