  • Device for injecting gas into the tubes of a chemical reactor
    Patent number: 9205391
    Abstract: A device for injecting gas into a plurality of vertical tubes of a chemical reactor from the bottom. The present invention relates to a device for injecting gas into tubes in a chemical reactor, and more specifically for injecting gas into the bottom of the tubes. The gas may be injected for the purpose of pressure testing the tubes, for blowing out the tubes in order to clean them, or for other purposes.

  • Device and method for dispensing catalyst pellets
    Patent number: 9149778
    Abstract: A device and method for dispensing catalyst pellets from a hopper to a chemical reactor. The hopper receives and holds the catalyst pellets at an elevation above the elevation of the chemical reactor. The flow of the catalyst pellets is controlled so they flow into and through a conduit in a widely spaced-apart arrangement to the chemical reactor. This controlled, spaced-apart flow is created by providing a sieve between a hopper and the conduit having openings small enough that the catalyst pellets form bridges above the openings, and then repeatedly breaking up the bridges in a controlled manner.

  • Device for unloading catalyst from a reactor vessel
    Patent number: 9138710
    Abstract: A device and method for automatic unloading of particles from the vertical tubes of a chemical reactor automatically feeds a fish tape into the bottom of the vertical tube to contact and dislodge the particles and automatically retracts the fish tape to allow the particles to fall out of the tube.

  • Device and method for dispensing pellets
    Patent number: 9138709
    Abstract: A device and method for dispensing pellets from a hopper to a desired delivery point. The hopper receives and holds the pellets at an elevation above the elevation of the desired delivery point. A fixed diameter opening is defined through which the pellets pass in order to reach a conduit that directs the pellets to the desired delivery point. A localized, direct mechanical force is imparted to pellets adjacent to the fixed diameter opening to break up bridges above the opening and allow the pellets to flow through the opening.

  • Carrying case conversion to desk
    Patent number: 8752912
    Abstract: A method for converting a watertight carrying case into a desk that includes mounting a bracket onto rearward projections from the case for permitting the case to serve as a desk without compromising its watertightness.
