  • Method and apparatus for the absorption of non-polar organic molecules on hydrocarbon block copolymers
    Patent number: 6056805
    Abstract: A method and apparatus are provided for the separation of non-polar organic molecules from fluids which utilize certain hydrocarbon block copolymers having soft and hard segments as absorbents. By employing hydrocarbon block copolymer having a particular concentration of soft and hard segments, optimum absortion is achieved while maintaining the mechanical structure of the absorbent so that it can withstand high fluid flow rates.
