  • Method using ethylene oxide to fumigate corrosion promoting microbes
    Patent number: 6605254
    Abstract: The present invention relates to a method of fumigating closed systems susceptible to microbially influenced corrosion (MIC). The method is particularly useful in a method for mitigating MIC in fire protection sprinkler systems.
    Type: Grant
    Filed: January 8, 2001
    Date of Patent: August 12, 2003
    Assignee: AlliedSignal Inc.
    Inventors: Anthony Mark Aguilera, Ronald Gordon Bitney, Stephen Alan Conviser, Barbara Ruth Decaire
  • Sterilizing gas compositions of ethylene oxide, pentafluoroethane and heptafluoropropane
    Patent number: 6432357
    Abstract: Non-flammable sterilizing gas compositions of ethylene oxide and a flame suppressant comprising pentafluoroethane and heptafluoropropane are useful in the gaseous sterilization of heat and/or moisture sensitive materials. The sterilizing gas compositions are environmentally acceptable and are more efficient and safer to use than conventional sterilant gas mixtures.

  • Shelf life improvement for ethylene oxide sterilant mixes
    Patent number: 5874113
    Abstract: A method of increasing the shelf life of a sterilant mixture of ethylene oxide and one or more halocarbons when the mixture is in contact with iron oxide on the surface of a storage vessel. Sufficient carbon dioxide is added to the mixture to reduce the reactivity of the iron oxide for converting ethylene oxide to reaction products of ethylene oxide. In an alternate embodiment, a hollow carbon steel vessel which holds a mixture of ethylene oxide and a halocarbon as a sterilizing gas has its inside surface passivated by forming a reaction product of iron oxide and carbon dioxide.
