A refining system includes a Peltier heat exchanger, an evaporation tank, and a nozzle. The Peltier heat exchanger is configured to receive unrefined liquid and comprising a Peltier cell. The nozzle is positioned within the evaporation tank and configured to receive unrefined liquid from the Peltier heat exchanger and provide unrefined liquid into the evaporation tank such that vapor is formed. The Peltier heat exchanger is configured to receive vapor from the evaporation tank while simultaneously receiving unrefined liquid. The Peltier cell is configured to heat unrefined liquid within the Peltier heat exchanger and cool vapor within the Peltier heat exchanger simultaneously.

The present invention provides a process for recovering glycol from a process stream comprising glycol, water, dissolved salts, and hydrocarbons. The process comprises subjecting the process stream to a salt-enrichment process to obtain a salt-enriched stream having a salt concentration higher than salt concentration of the process stream, and a salt-reduced stream; subjecting the salt-enriched stream to a glycol reclaiming process to separate the salts and at least a portion of the hydrocarbons from the salt enriched stream to obtain a substantially salt-free water-glycol stream; and blending the salt reduced stream from the salt-enrichment process with the substantially salt-free stream to produce a reclaimed water-glycol stream

The invention relates to methods, systems and apparatus for distributed management of raw water and internal combustion engine (ICE) gas emissions generated during industrial operations. One aspect of the invention at least partially utilizes a hot gas air knife to increase or partially increase surface area between a raw water and a hot gas in order to vaporize a proportion of the aqueous phase of the raw water and concentrate contaminants within a residual raw water concentrate. The water vapor generated by the vaporization process may be demisted, discharged directly to the atmosphere or alternatively condensed and captured for use. Another aspect relates to how the liquids and gasses interact to continuously flush the surfaces of the system which may help mitigate scaling issues. The invention may help facilitate rapid transfer of ICE combustion gas particulate and ICE combustion gas chemicals onto and into the raw water as it concentrates.

A system and method for converting non-potable water into potable water. Non-potable water, such as sea water or non-potable ground water, and the like, is fed down a conduit into a deep underground enclosure. Due to its extreme depth, the enclosure is geothermally heated above the boiling point of water at the pressure within the enclosure. The water boils and creates water vapor. The water vapor rises and can be drawn up through a vapor conduit to the surface. The water vapor can be condensed (and further purified, if necessary) into potable water. The steam can be used in a hybrid system, and condensed after being used for heating purposes or electrical production. Prior to being sent down into the enclosure, the source of non-potable water can be used in counter current heat exchange to reduce the temperature of the water vapor rising through the vapor conduit.

Apparatus and methods are related to treating waste water containing ammonium salts, which contains NH.sub.4.sup.+, SO.sub.4.sup.2−, Cl.sup.−, and Na.sup.+. In such a method, the pH value of the waste water to be treated is adjusted to a specific range in advance; sodium sulfate crystal and relatively concentrated ammonia are obtained by first evaporation, and then sodium chloride crystal and relatively dilute ammonia is obtained by second evaporation; alternatively, sodium chloride crystal and relatively concentrated ammonia is obtained by third evaporation, and then sodium sulfate crystal and relatively dilute ammonia are obtained by fourth evaporation. Ammonia, sodium sulfate, and sodium chloride from the waste water are recovered so that the resources in the waste water can be reused.

A water treatment system includes a primary evaporator and a secondary evaporator that is also a primary condenser. The primary evaporator relies on imparting rotational motion to the fluid to atomize it. The secondary evaporator may be a tube and shell heat exchanger. Embodiments include heat exchangers for using waste heat of various components. In an embodiment, concentrated effluent is recirculated and combined with influent to improve efficiency of the system to achieve zero liquid discharge and aid in continuous cleaning of the system.

A method and system is provided for reducing produced water disposal volumes utilizing waste heat generated by thermal oxidation. Waste heat generated by thermal oxidation can be used to vapourize excess water, and to treat and scrub the water vapour for final release into the atmosphere. The system can utilize excess heat remaining after thermal oxidation to produce water vapour.
