    Abstract: A gaseous hydrocarbon mixt. was passed through a liq. barrier consisting of complex-forming metal ions in aq. soln., supported in a semipermeable membrane. to give highly selective sepn. of aliph. unsaturated hydrocarbons. Thus, a mixt. contg. ethylene 41.0, methane 22.3, and C2H6 36.7% had C2H4 content 99.948 % ater permeation at 0.471 ml/cm2 min through a cellulose acetate filter, saturated in 1 mole aq. silver nitrate solution and sandwiched between 2 silicone polycarbonate films.

    Abstract: THERE IS DESCRIBED THE SEPARATION OF ALIPHATICALLY-UNSATURATED HYDROCARBONS FROM GASEOUS MIXTURES BY THE COMBINED USE OF FLOODED-CELL, LIQUID BARRIER PERMEATION AND METAL COMPLEXING TECHNIQUES. THE LIQUID BARRIER IS DISPOSED AS A CONTINUOUS, DISTINCT LIQUID PHASE IN CONTACT WITH A FILM MEMBRANE, AND THE BARRIER CONTAINS COMPLEXFORMING METAL IONS IN AQUEOUS SOLUTION. THE HYDROCARBON FEED GAS IS CONTACTED WITH THE LIQUID BARRIER CONTAINING A SURFACE-ACTIVE AGENT IN SOLUTION IN THE LIQUID BARRIER. THE SURFACE AGENT SERVES TO IMPROVE THE SELECTIVITY OF THE SEPARATION. THE METAL IONS IN THE LIQUID BARRIER MAY BE, FOR EXAMPLE, NOBLE METAL, NICKEL, MERCURIC, CUPROUS OR OTHER METAL IONS, AND MIXTURES OF THE METAL IONS, WITH OR WITHOUT OTHER CATIONS, MAY BE USED. THE SEPARATION OF ETHYLENE FROM ETHANE AND METHANE IS OF PARTICULAR INTEREST.

    Abstract: There is described the separation of carbon monoxide from gaseous mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is in contact with a semi-permeable film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The metal ions may be, for example, cuprous or other metal ions, and mixtures of these metal ions, with or without other cations, may be used. The separation of carbon monoxide from lower alkanes, e.g., ethane and methane, or hydrogen is of particular interest.

    Abstract: There is described the separation of aliphatically unsaturated hydrocarbons from gaseous mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is present essentially in a solid matrix that is a film membrane or is in contact with a film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The liquid barrier is in contact with a relatively non-volatile, hygroscopic agent that may be in solution in the liquid barrier or composited with the solid matrix, This agent may serve to reduce the loss of water from the liquid barrier which loss may otherwise be excessive. The hygroscopic agent when composited within a hydrophilic film membrane, may serve to increase the permeability of the film and maintain the strength of the film when it is swollen with the aqueous liquid barrier. The metal ions in the liquid barrier may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of the metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.

    Abstract: There is described the separation of aliphatically-unsaturated hydrocarbons of two to four carbon atoms from gaseous mixtures by the combined use of liquid barrier permeation and metal complexing techniques. The liquid barrier is in contact with a film membrane, and the barrier contains complex-forming metal ions in aqueous solution. The film membrane is contacted with a swelling agent to increase the selectivity of the separation and, preferably, increase permeation by the aliphatically unsaturated hydrocarbon to be separated. The metal ions in the liquid barrier may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of the metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.

    Abstract: There is described the separation of aliphatically-unsaturated hydrocarbons from gaseous mixtures by the combined use of flooded-cell, liquid barrier permeation and metal complexing techniques. The liquid barrier is disposed as a continuous, distinct or separate liquid phase in contact with a film membrane composite, and the barrier contains complex-forming metal ions in aqueous solution. The film is composed of a hydrophobic membrane having a hydrophilic surface on its feed inlet side. The hydrocarbon feed gas is contacted with the liquid barrier and the presence of the hydrophilic surface on the feed inlet side of the hydrophobic film membrane serves to improve the selectivity of the separation. The metal ions in the liquid barrier may be, for example, noble metal, nickel, mercurous, cuprous or other metal ions, and mixtures of metal ions, with or without other cations, may be used. The separation of ethylene from ethane and methane is of particular interest.
