  • Dual grid catalyst basket and method of independently supporting primary and secondary catalysts
    Patent number: 10744473
    Abstract: An ammonia oxidation catalyst basket design has two support grids. A first grid supports the primary catalyst and a separate, second grid supports the secondary catalyst. This dual grid design separates the two catalysts, and enables the catalysts to be independent of each other. Any interruption in the primary or the secondary catalyst does not impede or adversely impact on the structure or function of the other catalyst.

  • Furnace seal
    Patent number: 5006064
    Abstract: A gas seal for a bell-type annealing furnace is described. A ring supported by the furnace cover and a resilient pad supported by the base mate to form a gas seal when the cover is rested on the base. A cover-supported cooling jacket and a base-supported cooling jacket cooperate to enclose the seal when the cover is rested on the base. Load bearing structure is provided independent of the seal elements to avoid subjecting the seal elements to the weight of the furnace cover.
