  • Publication number: 20200230519
    Abstract: 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.

  • Patent number: 10703644
    Abstract: Embodiments of the invention provide a method for producing a treated water stream. The method includes receiving a feed stream including at least one substance dissolved in a water phase, and processing the feed water stream in a plurality of stages arranged in operation from a lowest temperature and pressure to a highest temperature and pressure, to produce the treated water stream and a concentrated stream. Each stage includes a vessel, a heat exchanger, an evaporator, and a condenser. Each evaporator is configured to evaporate an amount of water using one of direct heat or indirect heat. Each condenser is configured to condense at least a portion of steam generated by a successive stage. In accordance with various embodiments, the plurality of stages is arranged in series. In other embodiments, the plurality of stages is arranged in parallel.

  • Patent number: 10597313
    Abstract: Chlorination-assisted coagulation processes and systems are disclosed for removing organic and inorganic contaminants from aqueous compositions and streams such as produced water generated by petroleum production operations. The chlorination-assisted coagulation process includes converting at least a portion of chloride ions in the aqueous composition to hypochlorite ions or hypochlorous acid by passing an electric current through at least a portion of the aqueous composition under anaerobic conditions, the aqueous composition including the chloride ions, iron (II) compounds, and one or more organic compounds. The chlorination-assisted coagulation process further includes reacting at least a portion of the iron (II) compounds of the aqueous composition with the hypochlorite or hypochlorous acid to produce iron (III) ions, and coagulating the one or more organic compounds with the iron (III) ions to produce a plurality of insoluble solid particles in a treated aqueous composition.

  • Patent number: 10525415
    Abstract: Systems and methods for processing produced water containing organic compounds include a processing vessel; a filtration layer including a filtration material; and a cleaning system that provides a washing solution to the filtration material during a cleaning cycle. The filtration layer is configured such that at least a portion of produced water that enters the processing vessel during a processing cycle of the processing system passes through the filtration layer before leaving the processing vessel. The filtration material is a metal compound such as a metal hydroxide or a metal oxyhydroxide that is substantially insoluble in aqueous solution. The washing solution includes a reagent capable of reducing the metal compound to a reduced compound soluble in aqueous solution while not decomposing the organic compounds. The organic compounds such as crude oil may be recovered from the filtration layer material after the cleaning cycle, and the filtration layer may be regenerated.

  • Publication number: 20180275686
    Abstract: A method and apparatus for stabilizing gas/liquid flow in a vertical conduit by utilizing one or more flow stabilizing devices positioned inside the conduit along a structural support tube. The flow stabilizing devices are configured and dimensioned to accelerate the velocity of the flowing two-phase fluid mixture in the conduit to sustain upward liquid flow.
