Title: Enzymatically active high-flux selectively gas-permeable membranes

Abstract

An ultra-thin, catalyzed liquid transport medium-based membrane structure fabricated with a porous supporting substrate may be used for separating an object species such as a carbon dioxide object species. Carbon dioxide flux through this membrane structures may be several orders of magnitude higher than traditional polymer membranes with a high selectivity to carbon dioxide. Other gases such as molecular oxygen, molecular hydrogen, and other species including non-gaseous species, for example ionic materials, may be separated using variations to the membrane discussed.

  • A selectively gas-permeable composite membrane and a process for producing said composite membrane are described. The composite membrane comprises a polymeric material support and a thin membrane deposited on the support, said thin membrane being obtained by glow discharge plasma polymerization of an organosilane compound containing at least one double bond or triple bond. Alternatively, the composite membrane comprises a polymeric material support having an average pore diameter of at least 0.1 micron, a hardened or cross-linked polyorganosiloxane layer on the support, and a thin membrane on the polyorganosiloxane layer, said thin membrane being obtained by plasma polymerization due tomore » glow discharge of an organosilane compound containing at least one double bond or triple bond.« less
  • The less permeable zones of subterranean formations having temperatures above about 250* F are acidized by selectively plugging the more permeable zones with acid-soluble particulate diverting agents and then injecting a substantially anhydrous acid precursor into the formation. The acid precursor, which is a normally liquid halogenated hydrocarbon having one or two carbon atoms per molecule, hydrolyzes in situ to generate a hydrohalic acid. Subsequent to the placement of the acid precursor in the less permeable zones, the diverting agents may be solubilized in acid, such as the partially spent acid returning to the well.
  • This patent describes an asymmetric membrane having enhanced gas separation characteristics. It comprises: a relatively thin dense semipermeable skin region and a less dense, porous non-selective support region that serves to preclude the collapse of the skin region under pressure. The skin region is capable of selectively permeating a more readily permeable component of a feed mixture to be separated at a desirably high permeation rate, the membrane having washed and dried, and having been exposed in essentially dry form to an elevated temperature of from about 15{degrees} C. to about 1{degrees} C. less than the glass transition temperature ofmore » the membrane material under non-swelling conditions for a period of time sufficient to modify the membrane structure to create asymmetry therein and to increase its compaction resistance and collapse pressure. The asymmetric membrane exhibits enhanced selectivity and permeability characteristics, and advantageous combinations of selectivity and permeability, together with desirable compaction resistance and collapse pressure, on a repeatable basis, enhancing the uniformity and reliability of the membrane for use in gas separation operations.« less
  • A method is described for selectively removing hydrogen sulfide from a gas stream from a natural gas production well containing hydrogen sulfide and carbon dioxide. It consists of contacting the gas stream with a stoichiometric excess of a polyvalent metal chelate solution over the hydrogen sulfide the solution having a pH of about 8.0 to 9.2 for a time period less than 80 milliseconds to absorb hydrogen sulfide and not carbon dioxide, by flowing the gas stram and the solution past from two to six mixing elements in a static mixer, the gas stram being at a wellhead pressure ofmore » about 760-880 psig during contacting period.« less
