摘要： A process for removing and recovering a dissolved substance, either acid or a base, from an aqueous feedstream. The feedstream is contacted with an aqueous dispersed phase containing liquid membrane emulsion which removes the dissolved substance to the degree desired from the feedstream and absorbs it into the liquid membrane emulsion. The aqueous dispersed phase of the emulsion comprises a reagent which reacts with the dissolved substance by neutralization, allowing the dissolved substance to accumulate to a significant concentration in the emulsion before the spent emulsion is separated from the treated feed and coalesced into a membrane and a spent aqueous internal reagent phases. The spent aqueous internal reagent phase is subjected to electrolysis in a bipolar membrane cell which regenerates the dispersed reagent loaded internal aqueous phase in a composition suitable for recycle to emulsification and further feedstream treatment. The bipolar cell also generates an aqueous stream rich in dissolved substance from which the extracted dissolved substance can easily be recovered in pure form by conventional separation means.

摘要： A process for removing a species from a fluid which comprises (a) contacting said fluid with an emulsion, said emulsion having an external phase and an internal phase, said external phase being immiscible with said fluid and said species being permeable to said external phase; (b) permeating said species through said external phase into said internal phase; (c) converting said permeated species in said internal phase, into a species which is impermeable to said external phase; (d) separating said emulsion from said fluid; (e) converting the impermeable species of step (c) into a species which is permeable to said external phase by means of an oxidation-reduction reaction; and (f) permeating the permeable species of step (e) through said external phase. The instant process may be carried out in the reverse manner, i.e. the fluid including the species to be removed can be the internal phase of an emulsion or foam and thus permeate through the external phase. Preferably the fluid is an aqueous solution and the emulsion is a water-in-oil emulsion. The impermeable species of step (c) may be converted into a species which is permeable to said external phase by irradiating with light (UV or visible), by heating or by isolating said impermeable species from light. Preferably the permeable species in the internal phase is U.sup.+6 e.g. as UO.sub.2.sup.+2, which is trapped in the internal phase of the emulsion by reduction to U.sup.+4 an impermeable species, in the presence of a hydroquinone and light. Simultaneously hydroquinone is converted to quinone. After separation of the emulsion containing uranium in the +4 nonpermeable state from the aqueous solution, the emulsion is subjected to agitation in the presence of a fresh aqueous solution and in the absence of light whereby the quinone oxidizes the U.sup.+4 to U.sup.+6 e.g. UO.sub.2.sup.+2 which then permeates through said external phase into said fresh aqueous solution.

摘要： An apparatus is disclosed for generating a multiple phase dispersion and distributing said multiple phase dispersion as globules in a suspension phase. The apparatus comprises a conduit for introducing a first fluid under pressure into a first zone including a porous fluid dispersing layer. This first zone is in fluid communication with a second zone through the porous fluid dispersing layer. The second zone has introduced into it a second fluid under pressure through inlets. The first fluid is dispersed as bubble-like micro droplets in the second fluid by passage from the first zone through the fluid dispersing layer into the fluid in the second zone. An outlet zone is in contact with the second zone and comprises a perforated nonporous layer having an outer and inner surface and includes a porous flow distribution layer substantially in contact with the inner second zone facing surface of the nonporous layer. The multiple phase dispersion formed in the second zone enters the outlet zone through the porous flow distribution layer and exits the outlet zone as globules of predetermined size through the perforations where the outer surface of said perforated nonporous layer forms an interface with a suspension phase which is immiscible with the second fluid.The instant invention further relates to a process for generating multiple phase dispersions as globules in a suspension phase.

摘要： The instant invention relates to novel liquid membrane formulations, i.e., emulsions, which comprise an aqueous interior phase and a water-immiscible exterior phase; said water-immiscible exterior phase comprising an ethylene vinyl acetate copolymer and a solvent for this polymer. These compositions may additionally contain a water insoluble surfactant to stabilize the emulsions. In the most preferred embodiment, the aqueous interior phase comprises a strong acid, for example from about 1 to 10 percent by weight sulfuric acid. These emulsions are useful in liquid membrane processes for the separation of dissolved components from aqueous solution. Emulsions of the instant invention are characterized as showing very low swelling when contacted with aqueous solutions, especially at higher temperatures and thus are especially effective for use in the treatment of sour water feed streams by the liquid membrane technique.

摘要： This invention relates to a process for the removal of dissolved species from aqueous solutions, which comprises contacting said aqueous solution with an emulsion, said emulsion comprising an exterior phase which is characterized as being immiscible with said aqueous solution and yet permeable to said dissolved species, and an interior phase which contains a reactant capable of converting said dissolved species to a non-permeable form. The dissolved species permeate the exterior phase, into the interior phase where they are converted into nonpermeable forms and thus retained in the interior phase of said emulsion. The aqueous solution, depleted in said dissolved species, is separated from said emulsion and the emulsion cycled for reuse. In one preferred embodiment said dissolved species are ions, and an ion exchange compound is incorporated in the exterior phase of the emulsion, to promote the permeation of said ions through the exterior phase.

摘要： Organic compounds are removed from waste water streams by treatment with an emulsion of aqueous droplets containing a reagent coated by an organic liquid membrane containing surfactants through which the organic compounds in waste water will permeate and react in the aqueous droplets to form new chemical compounds and from which they can be recovered eventually by flashing off or emulsion breakup. The formation of new chemical compounds in the aqueous droplets prevents the organic compounds from permeating out of the emulsion. In a preferred embodiment of the invention phenol is removed from waste water streams.
