    Abstract: A process is provided for treating produced water recovered from an oil recovery process. An oil-water mixture is collected from an oil bearing formation. The oil-water mixture is directed to a separator that separates the oil-water mixture to yield produced water and an oil product. The produced water includes water, dissolved organics and dissolved inorganic solids. The produced water is directed to a crystallizer. In the crystallizer, the produced water is concentrated by heating the produced water. Concentrating the produced water causes the organic and inorganic solids to precipitate from the produced water and form solid crystals, including salt crystals. Further, concentrating the produced water in the crystallizer produces an organic melt including the solid crystals. Thereafter, the method or process entails cooling the organic melt such that the organic melt solidifies into an organic solid structure, and wherein substantially no free water is present in the organic solid structure.

    Abstract: A method for recovering heavy oil including recovering an oil-water mixture from a well and separating oil from the oil-water mixture to produce an oil product and produced water. The produced water is separated into a series of produced water streams. Each produced water stream is directed into each of a plurality of interconnected evaporators in a multiple effect evaporator. A first produced water stream is heated and vaporized to form a first vapor stream. The first vapor stream then heats and vaporizes a second produced water stream to form a second vapor stream. This process may continue wherein the second vapor stream heats and vaporizes a third produced water stream. The vapor streams are condensed to form a distillate that is directed to a steam generator. The steam generator then heats the distillate and produces steam to inject into an oil injection well.

    Abstract: A method of recovering oil from an oil well and producing steam for injection into an injection well is provided. After recovering an oil-water mixture from the oil well, oil is separated from the mixture to produce an oil product and produced water. In one process, the produced water is directed to an indirect fired steam generator which is powered by an independent boiler or steam generator. As water moves through the indirect fired steam generator, the same is heated to produce a steam-water mixture. The steam-water mixture is directed to the steam separator which separates the steam-water mixture into steam and water. The separated water is directed from the steam separator back to and through the indirect fired steam generator. This separated water is continued to be recycled through the indirect fired steam generator. Steam separated by the steam separator is directed into the injection well.

    Abstract: A process for recovery oil includes recovering an oil/water mixture from an oil well. Thereafter, the method includes separating oil from the oil/water mixture to produce an oil product and produced water having dissolved silica therein. The produced water is directed to an evaporator and produces steam and a concentrated brine. The method or process entails mixing a precipitant or crystallizing reagent with the produced water or the concentrated brine and causing the silica to precipitate from the produced water or the concentrated brine. Steam produced by the evaporator is condensed to form a distillate which is directed to steam generator. At the steam generator the distillate is heated to produce steam which is injected into an injection well, giving rise to the formation of the oil/water mixture.
