  • Publication number: 20190352206
    Abstract: A method of treating produced water, such as frac flowback, that includes pre-treating the produced water which is followed by a crystallization process that produces a condensate that typically includes ammonia and benzene. The ammonia and benzene concentration is reduced by biologically nitrifying and denitrifying the condensate. This produces an effluent that is directed to a solids-liquid separation process that removes suspended solids. The solids-liquid separation process produces another effluent that is subjected to a benzene polishing process that further reduces the benzene concentration of the effluent produced by the solids-liquid separation process.

  • Publication number: 20190322548
    Abstract: The present invention relates to a system and process for treating a feedwater wherein the system includes at least one or nanofiltration unit that receives a feed under high pressure and produces a concentrate that is directed to and held at low pressure in a concentrate accumulator. Generally the permeate or the inlet feedwater is maintained at a constant flow rate. Periodically the system is switched from a mode 1 or normal operating process to a mode 2 where the concentrate is drained from the concentrate accumulator. However, in mode 2, the feedwater is still directed into the system and through the RO or nanofiltration unit which produces the permeate and the concentrate.

  • Publication number: 20190256388
    Abstract: An oil or gas recovery process (10) is disclosed where resulting produced water includes silica. The process entails removing silica from the produced water via a two-stage process. In the first stage, magnesium oxide is injected into a Magnesium Dissolution Reactor (18) and mixed with the produced water to dissolve magnesium. Effluent from the Magnesium Dissolution Reactor (18) is directed downstream to a warm lime softener (22) where one or more alkaline chemicals are added to the produced water to raise the pH to approximately 10.0 to 11.5. Here, silica is co-precipitated with magnesium hydroxide and/or adsorbed onto magnesium hydroxide precipitates.

  • Publication number: 20190241439
    Abstract: The present invention relates to a process for producing sodium bicarbonate crystals. Sodium carbonate derived from TRONA ore is mixed with a treated mother liquor produced in a downstream process to form a sodium carbonate solution. The sodium carbonate solution is subjected to a crystallization process that produces sodium bicarbonate crystals. The sodium bicarbonate crystals are separated from the sodium carbonate solution to form a mother liquor that includes silica. To remove the silica in the mother liquor, the mother liquor is directed to a reactor where an aluminum salt is mixed with the mother liquor to precipitate hydrous aluminum oxide which adsorbs silica thereon. The hydrous aluminum oxide with adsorbed silica is removed from the mother liquor. This produces the treated mother liquor that is mixed with the sodium carbonate and which forms the sodium carbonate solutions.
