An apparatus for gas separation a composite gas separation membrane having a gas separation layer disposed on a surface of a porous support. The gas separation layer has a plurality of gas permeable inorganic nano-particles embedded in a dense polymer forming substantially only discrete gas transport channels through the dense polymer layer, wherein direct fluid communication is provided from a feed side of the composite gas separator membrane to the porous support. Preferably, the inorganic nano-particles are porous molecular sieve particles, such as SAPO-34, ALPO-18, and Zeolite Y nano-particles.

A highly cost-efficient method and process for producing oxygen from a gaseous mixture such as air results in substantial energy savings compared to conventional methods. The gaseous mixture is fed to a membrane absorber in which oxygen from the gas is absorbed, through a first membrane by an oxygen-absorbing liquid that possesses suitable absorption and desorption properties. The resulting oxygen-rich carrier liquid is fed to a membrane desorber in which oxygen from the liquid is desorbed through a second membrane, suitably with the aid of a vacuum. The oxygen product suitably has greater than 95% purity, or greater than 99% purity.

Adsorbent pellets coated with an outer nano-porous layer can be loaded with gas at loading pressures of 250 bar or greater, enabling a much higher loading than can be achieved at low pressures. The nano-porous layer provides nano-valves which can be sealed with an adsorbate such as ethanol or a hydrocarbon to close the nano-valves. The closed nano-valves maintain the high loading pressure inside the adsorbent pellets, and thus maintain the gas loading, during storage of the loaded nano-valved adsorbent pellets at much lower pressure. To release the gas, the nano-porous layer can be heated to a temperature sufficient to vaporize the adsorbate and open the nano-valves.

A method for separating the components of a mixture containing methyl methacrylate, water, and methanol in which the mixture is dehydrated in a first stage membrane unit, producing a dehydrated mixture. Methanol in the dehydrated mixture is removed in a second stage membrane unit, producing a retentate stream containing methyl methacrylate and substantially no said methanol.
