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.
