  • Patent number: 9057029
    Abstract: A method of producing oil, gas, and ash fertilizer from a feedstock includes inputting the feedstock into a reaction chamber having a wall, and combusting the feedstock in the reaction chamber. An electrical current flow is induced between the reaction chamber wall and the feedstock so as to cause arcing in the feedstock within the reaction chamber. Ash reaction byproducts migrate downward through the reaction chamber onto ash support structure, which is substantially electrically isolated from the reaction chamber wall. Gas and liquid reaction byproducts migrate upward through the reaction chamber to an upper chamber by a partial vacuum in the upper chamber, and are evacuated therefrom. The oil and gas are then separated from the evacuated gas/liquid products, providing the oil and the gas products. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.

    Abstract: A method for handling a substance from which a combustible gas volatilizes. A method for handling a substance from which a combustible gas volatilizes, in which, when such substance is handled inside an apparatus with a high degree of hermeticity, air is introduced into the apparatus and the substance is handled in a state in which the volatilized combustible gas is diluted to a concentration at which neither explosion nor fire occurs. With this method for handling a substance from which a combustible gas volatilizes, the combustible gas is diluted with air to a concentration at which neither explosion nor fire occurs, without using inactive gases such as nitrogen or carbon dioxide that have to be produced or purchased. Therefore, a substance from which a combustible gas volatilizes can be inexpensively and safely handled in operations such as mixing and storing.

    Abstract: An apparatus and method is presented for reducing mono nitrogen oxide emissions in a hydrocarbon processing furnace. A preferred embodiment hydrocarbon cracking furnace includes a firebox with a set of wall burners and a set of floor burners, the floor burners comprising secondary burner tips burning a fuel-rich mixture and positioned below primary burner tips burning a fuel-lean mixture. A portion of flue gases are recirculated from the primary burner combustion area to the secondary burner combustion area and back to the primary burner combustion area. The floor burners further comprise a set of steam injection ports that inject steam into a conical flow to contact flames at the primary burner tips, reducing flame temperature and thereby reducing thermal NOx. The steam injection ports are positioned in the firebox above the primary burner tips.

  • Publication number: 20110303135
    Abstract: An air preheater 100 is described having an air damper assembly 162 that partially restricts an air inlet 130 and a flue gas damper assembly 152 that partially restricts flue gas inlet 124 during periods of reduced boiler load. Restricting the flue gas inlet 124 reduces the effective surface area of the preheater causing more heat to pass to the cold end of the air preheater 100, reducing acid condensation and fouling. Restricting the gas inlet 124, increases gas velocity, thereby eroding accumulations in the air preheater 100, also reducing fouling. Restricting the air inlet 130 reduces the effective heat transfer surface area of the air preheater, which raises the gas temperature in the cold end of the air preheater and thereby reduces acid condensation and fouling.
