Abstract: The invention relates to a process for treating an aqueous solution from a subterranean formation of an oil and gas operation. The aqueous solution can be removed from the subterranean formation and treated in a heated centrifugal separator. The heated centrifugal separator can separate the kinetic hydrate inhibitor from the aqueous solution, and then the aqueous solution can be reintroduced into the subterranean formation.

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.
