摘要： A ring seal packer is used for sealing the inside of a specified diameter of API tube. The cylindrical body of the ring seal packer has a pair of circumferential grooves and a pair of rigid seal rings are provided in each such groove. The two rings collectively occupy substantially the entire length of the groove, with no more than a small clearance at the ends for forming a small area orifice through which fluid may flow. Each of the rings has an outside diameter larger than the inside diameter of a specified size of API tube. A longitudinal slot in the ring permits it to collapse to a diameter that fits into the tube as it is pushed into the well. A tang and notch arrangement keeps the rings from rotating relative to each other so that the slots are kept out of alignment. The ring seal packer does not use any elastomeric sealing materials.

摘要： A method and system for flue gas recirculation is disclosed which will minimize NOx production from hydrocarbon combustion. In the present invention a furnace having an oxygen-bearing primary source of combustion air, a mixing chamber, a combustion chamber in downstream communication with the mixing chamber and an exhaust section downstream of the combustion chamber is provided with a flue gas recirculation line. The recirculation line establishes communication between the exhaust section and the mixing chamber for the return of combustion products as a secondary source of combustion air which is relatively lean in oxygen and is combined with the primary source of combustion air in the mixing chamber. The ratio of flow rates for the primary and secondary sources of combustion air is controlled by a signal generated by a sensor which senses the oxygen concentration in the mixing chamber.

摘要： A method for constructing a multiple-stage gas separator assembly for downhole use upstream of a hydrocarbon producing submersible pump system is disclosed which has steps for forming a first-stage gas separator from a first conventional single-stage gas separator, connecting a coupling assembly to the first-stage gas separator at its downstream end, forming a second-stage gas separator from a second conventional single-stage gas separator by removing all lower flanges upstream of its fluid inlet, connecting the upstream end of the second-stage gas separator to the coupling assembly, and establishing a flow path from the first-stage liquid outlet to the second-stage inlet through the coupling assembly. A coupling assembly for joining first and second single-stage gas separators into a multiple-stage gas separator is also disclosed in which the coupling assembly has means for attaching to the downstream end of a first-stage gas separator, and a coupling housing defining a flow path between the liquid outlet of the first-stage gas separator and the fluid inlet of the second-stage gas separator. In an alternate embodiment, an adaptor is disclosed for inclusion into the coupling assembly which provides flow paths and a bushing for the second-stage gas separator formed from an alternate commercially available single-stage gas separator configuration.

摘要： A fireproof boom for containing flammable pollutants on water includes a flotation member, a heat-resistant water-sorbent material surrounding the flotation member and a protective fence surrounding the water-sorbent material. The flotation member is a series of cylindrical metal cans held end-to-end. The heat-resistant water-sorbent material draws water around the heat-sensitive flotation member, forming steam in the presence of flaming pollutant and allowing only the outer layer of heat-resistant material to become slightly singed. The protective fence surrounding the water-sorbent material is heavy steel wire woven in continuous spirals so that when the spirals are integrated with each other a diamond-shaped mesh is formed.

摘要： A submersible pump system and method for producing oil from gassy wells is disclosed in which at least first- and second-stage gas separators protect a submersible pump from vapor lock. The pump communicates with the production tubing and is driven by a shaft extending from a motor, through the first- and second-stage gas separators. The first-stage gas separator has a first-stage inlet through the housing in communication with the production fluid from the producing formation. A primary means for separating gas components from the production fluid is in communication with the first-stage inlet and expels separated gas into the annulus through a first-stage gas outlet and advances the liquid component of the production fluid through the first-stage liquid outlet. The second-stage gas separator has a second-stage inlet communicating with the first-stage liquid outlet and leading to a secondary means for separating the gas from the production fluid. The separated gaseous components are expelled through the housing and into the annulus at a second-stage gas outlet while the retained liquid components of the production fluid are presented to the pump, or to additional separation stages, through a second-stage outlet. The production fluid ultimately entering the pump inlet is substantially limited to the liquid components of the production fluid which is pumped through a pump outlet and up the production tubing.
