  • Membrane separation module
    Patent number: 5207906
    Abstract: An improved shellside feed, countercurrent flow, hollow fiber membrane separation module is provided wherein one or more flow tubes are incorporated into the conventional design. The flow tubes increase the efficiency of the membrane separation module by reducing undesirable flow patterns that are present in the conventional module.
    Type: Grant
    Filed: July 28, 1992
    Date of Patent: May 4, 1993
    Assignee: Permea, Inc.
    Inventors: Steven R. Auvil, James C. Sorensen, Daniel T. Diggs
  • Cross-flow permeator
    Patent number: 5043067
    Abstract: An improved cross-flow membrane module having a cylindrical housing containing semi-permeable membranes for separating a feed fluid is provided wherein a seal device is positioned in the permeate compartment of the module to separate the permeate stream passing through the semi-permeable membranes into two or more streams having differing component concentrations.

  • Membrane processed purified pipeline gas
    Patent number: 5006132
    Abstract: The present invention is directed to a method for removing a higher purity sidestream of a product gas from a main product pipeline gas flow stream of lower purity using a membrane selective for the product gas in contrast to impurities contained in the main product pipeline gas. The process avoids capital intensive apparatus or energy intensive processing and returns the reject gas from the membrane to the pipeline for inclusion with the main product pipeline gas. Recovery of a higher purity component of a main pipeline product gas containing that component is also contemplated.

    Inventors: Stephen P. DiMartino, Sr., James C. Sorensen
  • Method for gas separation
    Patent number: 4761164
    Abstract: The present invention is a process for separating one or more components of a gas mixture. The process comprises passing the gas mixture over a membrane, which is selectively permeable to the component being separated, due to one or more reversible reactions between the component desired to be separated and a layer of active molten material immobilized in a suitable support material and/or encapsulated in a non-porous gas permeable polymer material.
    Type: Grant

  • Nectarine tree
    Patent number: PP4518
    Abstract: A new variety of nectarine discovered as a sport of a Regal Grand growing in Fresno County, located in the San Joaquin Valley of California. The new variety is characterized by fruit which, when mature, is highly colored, keeps well and is particularly suited for shipping.
