摘要： A method for treating produced water from a fracking operation is disclosed. The produced water is first fed to a compact separator for the removal of suspended materials. This produced water is then treated for dissolved gases and suspended oils before being fed to a crystallizer where salts are separated from the produced water thereby producing fresh water for reuse or other means. Alternatively, the produced water may be fed to a disinfection system and a concentrator depending upon the composition of the produced water.

摘要： Disclosed is a process to remove neutrally buoyant metal particles composed of solid particles and droplets of oil from water such as produced water from petroleum production or refinery wastewater. In one aspect, the water is contacted with oleophilic adsorbent materials which adsorb the neutrally buoyant metal particles. Also disclosed is a process for removing metal particles from a fluid volume that includes crude oil and/or condensate. The fluid volume is washed with a volume of water to form a volume of wastewater, thereby transferring at least a portion of the metal particles from the fluid into the wastewater. The volume of wastewater including the transferred metal particles is then contacted with an oleophilic adsorbent material wherein the neutrally buoyant metal particles are adsorbed by the adsorbent material. The adsorbent material is then separated from the wastewater. Finally, the treated wastewater is used to wash the crude and/or condensate.

摘要： A method for removing hydrogen sulfide from a liquid stream is described. The method includes contacting the liquid stream including a first amount of hydrogen sulfide with a first side of a porous gas-liquid separation membrane. The hydrogen sulfide moves through the pores of the membrane from the first side to a second, opposite side of the membrane. The method further includes contacting a receiving fluid with the second, opposite side of the porous membrane to receive the hydrogen sulfide. The liquid stream is thus converted to a reduced-sulfide liquid stream having a second amount of hydrogen sulfide that is less than the first amount of hydrogen sulfide. A method for removing ammonia from a liquid stream is also described.

摘要： A process is described for recovering alkali-chloride and alkali-sulfate salts from a salt solution. The salt solution comprises alkali metal, chloride and sulfate ions and is directed to a hydrous salt crystallization unit (28) which crystallizes hydrated sulfate salts that comprise sulfate and at least one alkali metal. A purged solution from the hydrous salt crystallization unit (28) is directed to a chloride salt crystallization unit (38) while the hydrated sulfate salt crystals are melted to form an aqueous sulfate solution which is directed to a sulfate crystallization unit (32). Anhydrous sulfate salts are crystallized from the aqueous sulfate solution to form sulfate salt crystals comprising sulfate and at least one alkali metal. In the chloride salt crystallization unit (38), chloride salt is crystallized to form chloride salt crystals. At least a portion of the purges from the sulfate and chloride salt crystallization units (32, 38) is directed to the hydrous salt crystallization unit (28).
