Method and plant for fluid purification by distillation comprising a reservoir (1) with a fluid containing diluted solids provided with an impurities filter on its outlet (2); a pump (3) connected to the reservoir outlet (1) and set up to increase the fluid containing solids pressure and temperature; and a heat area (4) for the fluid containing solids comprising a plurality of ducts contacting with a heat transfer fluid; and, furthermore, comprising a convergent-divergent nozzle (5) connected to the heat area outlet (4) and set to increase the biphasic liquid-vapor fluid speed so the diluted solids contained in the fluid already heated settle in a solids reservoir (6), whereas the fluid passes to a condenser (7) and then to a purified fluid reservoir (8) already in liquid state.

A method may include providing a humidification-dehumidification unit proximate one or more abandoned wells, circulating a water feed through the one or more abandoned wells, using geothermal heat in the one or more abandoned wells to heat the water feed, directing the heated water feed to the humidification-dehumidification unit, and treating the heated water feed in the humidification-dehumidification unit to provide purified water.

A system for the disposal of liquid waste includes a portable container body having an open interior and a liquid waste inlet for receiving liquid waste containing solids. A liquid waste holding tank is provided within the open interior of the portable container body for receiving the liquid waste from the liquid waste inlet. A liquid-solid separator within the open interior of the portable container body produces a solid waste and a separated liquid waste. A conduit directs the liquid waste from the liquid waste holding tank to the liquid-solid separator. An evaporator within the open interior of the portable container body heats the separated liquid waste to evaporate and remove water from the separated liquid waste as water vapor and produces a concentrated liquid waste. A safety containment system prevents the liquid waste from escaping to the environment. A method for disposing of liquid waste is also disclosed.

The present invention discloses systems and methods for supplying hot water for primary extraction in the oil sands bitumen extraction process. Direct contact process and method for producing hot water using mature fine tailings are provided by employing a double staged submerge arrangement with a thickener vessel containing a submerged fuel burner and a hot water vessel containing a submerged fuel burner, a flash submerged arrangement with a flash concentrator vessel containing or adjacent to a fuel burner and a hot water vessel containing a submerged fuel burner or a triple cascade arrangement with a flash concentrator vessel, a thickener vessel containing a submerged fuel burner and a hot water vessel containing a submerged fuel burner.

A small processor produces potable water from contaminated water. Its components mount in a hermetically sealed housing, which include a boiler-condenser assembly and a compressor unit. Contaminated water is injected onto one or more aluminum shells' inside surface of the boiler-condenser assembly. Shell rotation enhances boiling heat transfer by causing the water to form thin films on the shells' inside surface. Shell rotation also enhances condensing heat transfer by assisting in removing the purified condensate from the shells' outer surface. The change of phase heat of condensation energy from vapor to liquid transfers through the shells to the boilers to cause boiling. Vapor boiled inside the boiler chambers flows toward the compressor, which raises the vapor's pressure and temperature to drive the process. Shell rotation causes centrifugal force that holds and directs concentrated un-boiled remaining water on the shells' inside walls towards the output pumps. Wipers mounted adjacent each shell's boiler surface smooth contaminated water. Wipers adjacent the condenser surfaces help remove condensate from that surface to present a clean condenser for improved condensation.

A system and apparatus for treating and disposing of produced water in conjunction with gas turbine exhaust gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated with ozone injection in a scrubber with heat applied through introduction of gas turbine exhaust gas. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system. The evaporated salts and solids are then treated via chemical stabilization in a mixing system with chemical reagents to prevent the residual form from being hazardous. The residual material is then stored and disposed of properly.

Methods, systems, and apparatus, relate to a method for carbon capture from sea water. A first source of sea water into a reverse osmosis chamber. Reverse osmosis is performed on the sea water to produce fresh water and brine. The brine is provided to an electrolyzer. A current is passed through the brine and fresh water, thereby producing a hydroxide solution in a cathode chamber of the electrolyzer. The hydroxide solution is collected and placed into a contacting chamber and new sea water introduced. Precipitates are produced comprising at least calcium carbonate and magnesium carbonate.

An energy efficient distillation process is provided. Energy efficiency originates from a combination two processes: a) the vaporization occurring with high pressure and high temperature, which decreases enthalpy of vaporization, where the enthalpy of vaporization can be equal to zero if the vaporization occurs to critical state of vaporizing fluid; and b) thermal energy and hydraulic energy of vaporized fluid return to the feed liquid with the system of heat exchangers and pressure exchangers. The energy efficient distillation herein can be applied in multiple existing distillation processes.

A seawater distillation system for distilling seawater and brine and removing salt. The seawater distillation system includes an apparatus having at least a vessel, a separation assembly, and at least one mist eliminator. The vessel may be adapted to hold a volume of seawater comprising a volume of salt, wherein vessel is one of externally heated and internally heated to evaporate the volume of seawater to a volume of steam and to precipitate the volume of salt. The separation assembly may be operably engaged with the vessel, wherein the separation assembly is configured to separate the volume of salt from the volume of seawater inside of the vessel. The at least one mist eliminator may be operably engaged with the vessel and positioned vertically above the separation assembly, wherein the at least one mist eliminator is configured to eliminate water droplets and salt from the volume of steam.

Disclosed are methods of dewatering solid byproduct. In some embodiments, the solid byproduct contains particles and is produced from a fermentation process for making an oxygenated compound such as ethanol. The method comprises a chemical sequence for conditioning (pre-treating) the solid byproduct to be dewatered. The solid byproduct (in water) is treated with alkaline material to increase its pH to about 7-8.5. Coagulant is added to the alkaline-treated solid byproduct to reduce charge on the solid byproduct. An agglomerating polymer is then added to increase the average size of the solid byproduct particles to a desired size (e.g., at least about 1 mm). Dewatering can further use known technologies such as screw press, belt press, filter press, centrifuge, and/or a dryer to separate the conditioned or pre-treated byproduct from water. Also disclosed are methods of producing oxygenated product, as well as methods of producing animal feed and/or fertilizer, respectively.
