  • Low cost, low emissions natural gas combustor
    Patent number: 6374615
    Abstract: A combustor dome for use in a combustor has an igniter mounted in a central bore. Moving outward from the bore is a concentric pilot fuel passageway. Concentric about the pilot fuel passageway is an air passageway. Lastly, concentric about the air passageway is a premix passageway. The outlets of the pilot fuel passageway, the air passageway, and the premix passageway are generally coplanar.

  • Catalytic combustor for gas turbines
    Patent number: 6223537
    Abstract: In a catalytic combustor for gas turbines, the dimensions of the preheater and premix duct, the location of the preheater and premix fuel nozzles, and the number and location of air orifices in the combustor can inner liner are configured to result in low NOx production during both preheating combustion and catalytic combustion. Placement of the air orifices helps reduce the potential for autoignition within the premix duct, while enhancing fuel-air mixture uniformity upstream of the catalyst. At the same time, the overall configuration is optimized to result in the relative compactness of the catalytic combustor, making it particularly suitable for applications such as automotive turbine engines and microturbines.

  • Multi-stage wax hydrocrackinig
    Patent number: 4994170
    Abstract: A process for hydrodewaxing a petroleum or shale oil fraction, e.g., petroleum distillate, over a shape selective zeolite in the presence of hydrogen wherein the dewaxing is conducted in at least two stages, with some of the hydrogen added to first stage effluent. Dewaxed feed, and a high octane gasoline byproduct are obtained as products.

  • Storage tank and floating roof with a gauge well having a floating seal therein
    Patent number: 4260068
    Abstract: A floating vapor seal is suspended in a slotted gauge well that extends through a floating roof of a petroleum product storage tank. It has a flexible, product resistant layer that contacts the inside walls of the gauge well near the level of product in the well. The floating roof contacts the product around the gauge well and has a seal between it and the outside of the well.
