Abstract: The invention relates to a method and apparatus for treatment of produced or process water from hydrocarbon production to reduce the volume of the produced or process water while simultaneously reducing the salinity of a highly saline stream, for example, the brine from a seawater desalination plant. The method includes causing a feed stream comprising produced or process water to flow through the lumen of a hollow fiber osmotic membrane 4 which is immersed in an open channel 2 or tank of flowing draw solution 6 which has high salinity. In this way, water from the feed stream is drawn through the osmotic membrane 4 by an osmotic pressure differential caused by the difference in salinity between the feed stream and the draw solution 6.

Abstract: 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.
