  • Patent number: 10561978
    Abstract: A multi-stage polymeric membrane module system separates a gas, such as air, into components of high purity. In at least two of the stages, a portion of the retentate gas is directed into the low-pressure side of the module, to act as a sweep gas. The use of the sweep gas reduces the partial pressure of permeate gas on the low-pressure side of the membrane, and therefore improves the flow of permeate through the membrane. In a preferred embodiment, there are three modules. The output streams are taken from the retentate outlet of one module, and from the permeate outlet of another module. The output streams have very high purity, relative to the number of modules required, as compared with systems of the prior art.

  • Patent number: 9764275
    Abstract: A module having polymeric gas-separation membranes is capable of operation in extreme temperature environments. In one embodiment, the module includes polymeric fiber membranes, a tubesheet for holding the membranes, and a sleeve encasing the membranes, all of which are made of materials having coefficients of thermal expansion which differ from each other by not more than about 10%. In another embodiment, the membranes, the tubesheet, and the sleeve are all made of materials having a glass transition temperature greater than a highest anticipated temperature of operation of the module. In another embodiment, the module includes a head, and a clamshell having multiple protrusions which engage corresponding grooves in the head and in at least two grooves formed in the tubesheet.

  • Publication number: 20160303507
    Abstract: A gas separation membrane module includes hollow polymeric fibers held within a casing, the fibers being anchored by tubesheets at the ends of the casing. A filter material, preferably made of an activated carbon fiber fabric, is integral with the module, such that all gas entering the module must pass first through the filter before reaching the fibers. The filter may have the form of a circular pad affixed to one of the tubesheets. Alternatively, the filter could be a wrap disposed around the fibers, inside the casing. In another alternative, the filter could be provided within a core tube, in cases where a feed gas is introduced through the core of the module. In another embodiment, the filter could be provided in a separate unit from the gas separation module.
