  • Patent number: 7377956
    Abstract: Method and system for processing natural gas containing contaminants through the use of one or more rotary screw compressors. A natural gas containing a contaminant (e.g., water or carbon dioxide and/or hydrogen sulfide) and a contaminant removing agent are combined and processed within a rotary screw compressor. The contaminant removing agent may be a dehydrating agent such as a glycol or a carbon dioxide and/or hydrogen sulfide removing agent such an amine. The method and system of the present invention also may employ a series of rotary screw compressors to process natural gas containing a plurality of contaminants.

  • Patent number: 6955705
    Abstract: Method and system for compressing and dehydrating wet natural gas produced from a low-pressure well using a rotary screw compressor. A dehydrating agent is combined with wet natural gas within a rotary screw compressor. Operation of the rotary screw compressor causes compression and dehydration of the wet natural gas to produce a compressed dry natural gas. Engine exhaust produced by the engine which powers the rotary screw compressor may be used to remove water absorbed by the dehydrating agent and thereby recover the dehydrating agent for re-circulation in the system.

  • Patent number: 6398851
    Abstract: Exhaust gases from an internal combustion engine operating with leaded or unleaded gasoline or diesel or natural gas, are used for energizing a high-speed gas turbine. The convoluting gas discharge causes a first separation stage by stratifying of heavier and lighter exhaust gas components that exit from the turbine in opposite directions, the heavier components having a second stratifying separation in a vortex tube to separate combustible pollutants from non-combustible components. The non-combustible components exit a vortex tube open end to atmosphere. The lighter combustible, pollutants effected in the first separation are bubbled through a sodium hydroxide solution for dissolving the nitric oxide, formaldehyde impurities in this gas stream before being piped to the engine air intake for re-combustion, thereby reducing the engine's exhaust pollution and improving its fuel economy. The combustible, heavier pollutants from the second separation stage are piped to air filter assemblies.

  • Patent number: 5136843
    Abstract: The apparatus for burning the contaminated soot particles in the exhaust gases of diesel motors of vehicles comprising in the exhaust gas line a housing with a burner operated with a fuel/air mixture for burning the contaminated particles in the exhaust gas flow. The housing comprises a rotatably supported hollow cylinder through which the exhaust gases flow. The housing and the hollow cylinder bound the combustion space of the burner, wherein the hollow cylinder comprises drive vanes and the exhaust gases of the diesel motor and/or the exhaust gases of the burner act upon the drive vanes and wherein the exhaust gases of the burner heat the hollow cylinder up to the combustion temperature of the soot particles. The arrangement can be also made in such a way, that the exhaust gases and/or the combustion gases of the burner flow through bores into the perforated hollow cylinder and exit through the one open end face of the perforated hollow cylinder.

  • Patent number: 5121602
    Abstract: A pollution control apparatus is shown for use on automobiles and trucks. This pollution control apparatus fits on the automotive exhaust pipe. A collector unit is secured between the exhaust pipe and tail pipe. The collector unit has a pair of blowers or bladed rotors which are impinged by a mixture of exhaust gases and water which causes the water droplets and dissolved and entrained materials to separate and drain through outlet drains. Water is injected into a U-shaped trap between exhaust pipe and the collector unit. Water from the bottom of the collector unit is pumped by a pump to a reservoir and entrained material is separated by a filter. Water from the filter drains by gravity through a radiator coil and thence to the reservoir from which it flows through vacuum valve to a U-shaped fitting. The water is injected into the exhaust gas stream to wash out entrained and soluble material. The mixture flows through blowers which cause the entrained and water-dissolved material to separate as described.

  • Patent number: 4235845
    Abstract: The invention provides a pair of exhaust gas separation stages comprised in a gas separating vortex tube having an exhaust gas operated turbine impeller or rotor with stator wheels. The system combination also includes a mixing chamber for heavier and lighter combustible gas components subsequent to separation, wherein such components are directed to the top surface of a water charge in the mixing chamber, and further includes a chemical separation chamber downstream of the mixing chamber containing specified chemicals wherein the mixing chamber removes substantial parts of formaldehyde and nitrous oxides while the chemical chamber removes acetaldehyde and higher aldehyde components. Finally, the gas mixture from the chemical separation chamber passes through a water scrubber to remove traces of chemicals which may be used, to keep traces of chemicals in the chemical chamber from reaching the engine.
