The present invention relates to methods of separating one or more components from a feed composition, methods of desorbing one or more components from an absorbent fluid, as well as systems and apparatus that can carry out the methods. In one embodiment, the present invention provides a method of separating one or more components from a feed composition including contacting at least some of a first component of a feed composition including the first component with an absorbent fluid, to provide a contacted composition and a used absorbent fluid including at least some of the first component contacted with the absorbent fluid. In some embodiments the absorbent fluid can be an organosilicon fluid including an organosilicon including at least one of a hydroxy group, an ether group, an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, and a polyether group. In some embodiments, during the contacting the feed composition can be contacted to a first side of a membrane while the absorbent fluid is contacted to a second side of the membrane. In some embodiments, the membrane can be a silicone membrane.

The invention relates to a membrane having a pore-free separating layer including a polymer mixture for separating simple alcohols and water from their mixtures with other organic fluids by means of pervaporation or vapor permeation. In accordance with the invention, the polymer mixture is composed of at least two polymer components which are taken from the group of polymer components which includes of the following polymer components: Polyvinyl alcohol, other polymers such as poly NN-dimethylaminoethyl methacrylate (poly DMAEMA), a copolymer of DMAEMA and N-vinyl pyrrolidone (NVP) or of DMAEMA and N-vinyl caprolactam (NVCL), a terpolymer of DMAE, NVP and NVCL or of vinyl acetate ethylene vinyl chloride or from vinyl chloride ethylene acrylic ester or from vinyl acetate vinyl chloride acrylic ester. The invention further relates to the use and to a method for manufacturing a membrane in accordance with the invention.

This composite hollow fiber membrane comprises a non-porous homogeneous layer which is gas-permeable and a porous support layer which supports said homogeneous layer, and is characterized in that the non-porous homogeneous layer is hydrophobic and the polyolefin resin constituting the porous support layer contains a hydrophilic additive. By this means, a composite hollow fiber membrane for use in degassing can be provided that is hydrophilic, has high water vapor permeability, and can solve the problem of gas permeability being reduced due to condensate in the porous substance.

The present invention relates an excess microbubble hydrogen preparation device, which belongs to the technical field of electrolysis equipment. The device comprises a water container which is respectively provided with a water inlet and a water outlet; at least one pair of a cathode and an anode are arranged within the water container; a water-permeable porous membrane is clamped between the coupled cathode and anode with no gap; the area of the inside of the water-permeable porous membrane opposite the cathode or the anode is smaller than the area of the inside of the cathode or the anode opposite the water-permeable porous membrane, and the thickness of the water-permeable porous membrane is less than 5 mm. The device can generate massive amounts of ultroultra-micro bubble hydrogen, and at the same time, very little oxygen is generated.

The present disclosure provides a laminate for humidification including a porous reinforcing material, and a non-porous membrane that is laminated on at least one surface of the porous reinforcing material.
