  • Publication number: 20230266194
    Abstract: Described herein is an apparatus for detecting leakage of an emanated gas from an inorganic compound stored in a container. The apparatus includes an enclosure structured to conceal a closure secured to the container. A flow creation device is fluidically connected to the enclosure, the flow creation device is configured to create a flow of the emanated gas from the enclosure. Further, a gas monitoring unit is fluidically connected between the enclosure and the flow creation device. The gas monitoring unit is structured to receive at least a portion of the emanated gas from the enclosure and detect concentration of at least one constituent present in the emanated gas. The disclosure also includes a system incorporating a control unit for detecting leakage of an emanated gas from an inorganic compound stored in a container.

  • Patent number: 8017090
    Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.
