    摘要： Process and apparatus for the separation and purification of oxygen and nitrogen as well as a novel membrane useful therein are disclosed. The process utilizes novel facilitated transport membranes to selectively transport oxygen from one gaseous stream to another, leaving nitrogen as a byproduct. In the method, an oxygen carrier capable of reversibly binding molecular oxygen is dissolved in a polar organic membrane which separates a gaseous feed stream such as atmospheric air and a gaseous product stream. The feed stream is maintained at a sufficiently high oxygen pressure to keep the oxygen carrier in its oxygenated form at the interface of the feed stream with the membrane, while the product stream is maintained at a sufficiently low oxygen pressure to keep the carrier in its deoxygenated form at the interface of the product stream with the membrane. In an alternate mode of operation, the feed stream is maintained at a sufficiently low temperature and high oxygen pressure to keep the oxygen carrier in its oxygenated form at the interface of the feed stream with the membrane and the product stream is maintained at a sufficiently high temperature to keep the carrier in its deoxygenated form at the interface of the product stream with the membrane. Under such conditions, the carrier acts as a shuttle, picking up oxygen at the feed side of the membrane, diffusing across the membrane as the oxygenated complex, releasing oxygen to the product stream, and then diffusing back to the feed side to repeat the process. Exceptionally and unexpectedly high O.sub.2 /N.sub.2 selectivity, on the order of 10 to 30, is obtained, as well as exceptionally high oxygen permeability, on the order of 6 to 15.times.10.sup.-8 cm.sup.3 -cm/cm.sup.2 -sec-cmHg, as well as a long membrane life of in excess of 3 months, making the process commercially feasible.

    摘要： A processor for processing undeveloped photographic film discs carried on a rotatable spindle includes a conveyor for conveying the spindle intermittently from a first end of the processor along a generally horizontal conveyor path to each of a plurality of stations along the conveyor path. The intermittent conveying of the spindle by the conveyor is cyclical, with each cycle of the conveyor having a transport portion during which the spindle is conveyed from one station to another and a processing portion during which the spindle is positioned at one of the stations for processing. The spindle and film discs mounted thereon are rotated when positioned for processing at each station, and a rotation sensor at each station senses a failure of the spindle to be rotated. The processor also has a spindle sensor which senses the presence of the spindle adjacent the first end of the processor. An indicator responsive to the spindle sensor, the conveyor and the rotation sensor identifies any station at which the spindle is located and at which the rotation sensor senses the failure of the spindle to be rotated.

    摘要： A process and apparatus for separating carbon dioxide from gas, especially natural gas, that also contains C3+ hydrocarbons. The invention uses two or three membrane separation steps, optionally in conjunction with cooling/condensation under pressure, to yield a lighter, sweeter product natural gas stream, and/or a carbon dioxide stream of reinjection quality and/or a natural gas liquids (NGL) stream.

    摘要： An improved process and process train for catalytic reforming of hydrocarbons. In its most simple form, the invention includes four unit operations or steps: the reforming itself usually carried out in a series of reactors; one or more steps to separate the reformate liquid product from overhead gases, predominantly C1-C6 hydrocarbons and hydrogen; one or more treatment steps to recover hydrogen from the overhead gases, and one or more treatment steps, including a membrane gas separation step, for the waste gas from the hydrogen recovery step. The process provides improved recovery of hydrogen and LPG, and reduces the amount of gas sent to the fuel line.

    摘要： Processes for providing improved methane removal and hydrogen reuse in reactors, particularly in refineries and petrochemical plants. The improved methane removal is achieved by selective purging, by passing gases in the reactor recycle loop across membranes selective in favor of methane over hydrogen, and capable of exhibiting a methane/hydrogen selectivity of at least about 2.5 under the process conditions.
