Abstract: Rich natural gas is first compressed, and then cooled by a series of heat exchangers and an ambient air cooler. The cooled mixture of natural gas, natural gas liquid (NGL), and water is first separated in a high-pressure three-phase separator. NGL flows through a depressurization valve and NGL is separated from gas in a second separator for storage and transport such as in a conventional propane tank. A resulting lean natural gas is suitably conditioned for internal combustion, compressed natural gas processing, or liquid fuel processing.

Abstract: Compressed rich natural gas is divided into a cooling gas stream and a fuel gas stream. The cooling gas stream is depressurized. The cooling gas and the fuel gas are then heat exchanged to provide a first cooling step to the fuel gas. The cooled fuel gas continues into a second cooling step in a second heat exchanger, and then flows into a separator vessel where liquids are removed from the bottom of the separator and conditioned fuel gas exits the top of the separator. The conditioned fuel gas from the separator and produced from its influent is depressurized and heat exchanged to provide the second cooling fluid for the second heat exchanger.

Abstract: Rich natural gas is first compressed, then ambient air cooled and separated into lean natural gas, NGL and water. Hydrate formation during decompression of the lean gas is precluded by either heating the lean natural gas or mixing the lean natural gas with methanol or other additive before depressurization. Similarly, hydrate formation in the NGL is also precluded by either heating the NGL or mixing the NGL with methanol or other additive before depressurization. The NGL is conditioned for storage and transport in common propane tanks by a stabilizer or two-phase separator. The lean natural gas can be used for internal combustion, liquefied natural gas, compressed natural gas or liquid fuel processing.

Abstract: Volatile organic compounds are removed from crude oil by adding heat upstream of a vapor recovery tower. The heat input may either be sufficient to break the emulsion as in a here treater or extra heat may be added to stabilize the crude oil. Produced gas may be recovered as NGL in one or more cooling stages. Produced gas, whether partially recovered or not, may be used as fuel for said heater treater, other combustion device or compressed into a pipeline.

Abstract: Volatile organic compounds are removed from crude oil by adding an amount of stabilization energy to crude oil upstream of, or directly into, a crude oil stock storage tank or by recovering and condensing vapors from tank vent gas. Produced gas may be recovered as NGL in one or more cooling stages. Produced gas, whether partially recovered or not, may be used as fuel for the heater treater, other combustion device or compressed into a pipeline.

Abstract: Rich natural gas is dried in a water scavenger unit, and then purified in a refluxed absorber. The refluxed stream for the absorber is a stream of predominantly methane condensed by cryogenic refrigeration. The refluxed absorber is operated below the critical point of methane, to allow condensation to occur. Liquefied natural gas is condensed in a cryogenic box, and then further cooled. Natural gas liquid from the refluxed absorber is stabilized for storage and transport.

Abstract: Air from the intake manifold and fuel from an injector is mixed by a Venturi of adjustable flow path, upstream of an intake valve. Fuel is injected into the throat of the Venturi to improve vaporization and to premix the fuel and air before the mixture enters the combustion chamber. A pressurized manifold from a supercharger or turbocharger system can enhance the action of the Venturi. The Venturi mixing enhances combustion efficiency, resulting in increased power and fuel economy for an internal combustion engine.

Abstract: A Hinge Assembly for supporting a storge-type door in a cabinet, the assembly including a cabinet plate in the form of a square having guide grooves along two sides, the grooves intersecting at one corner of the square, a door plate mounted on the cabinet plate for rotary motion between a first position in alignment with one edge of the door plate in alignment with one edge of the first plate to a second position with one edge of the door plate in alignment with the other edge of the cabinet first plate, the door plate having two guide members on the one edge, the guide members being aligned in one of the grooves in the first position and moveable into the other of the grooves on rotation of the door plate with respect to the cabinet plate whereby the door plate rotates within the angle formed between the guide grooves, and a pivot post on one of the plates and a guide member on the other of the plate having a track to define the path of motion for the pivot post on rotation of the door plate with respect to

Abstract: A liquid distributor for a gas-liquid contact column, which liquid distributor comprises a plurality of elongated distributors extending across the general cross section of a gas-liquid contact column, and secondary distributing troughs located on each side of the distributor, the secondary distributor troughs containing a deflection plate having an upper section and a lower section and a support plate which connects the deflection plate and spaces the deflection plate apart from the liquid distributor, the support plate having large openings for the upward passage of a gas and smaller openings located near the intersection of the support plate with the deflection plate to permit the liquid splashing from the orifices of the liquid distributor against the deflection plate to flow downwardly against the wall surface of the lower portion of the deflection plate and to be distributed through multiple drip points on the lower edge of the deflection plate in the lower portion of the gas-liquid column.
