Abstract: A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element, and in a toroidal vortex ring created in the annular space. The area and geometry of the helical path, the conical cavity, and the inner and outer tubes is optimized to provide efficient separation at varying gas flow rates and at varying liquid loads.

Abstract: A refining system for refining a feed gas comprising hydrocarbons and hydrogen sulfide having a first concentration of hydrogen sulfide including a first part for producing a stream of a first processed feed gas, and a second part for producing a second stream of a second processed feed gas from the stream of the first processed feed gas using a separation process for H2S removal.

Abstract: This invention is a dust removal system for dust gas which comprises at least an atomizer. The atomizer comprises an atomizing chamber and an atomizing mechanism; the atomizing chamber includes an inlet for the dust gas and an outlet for the gas after mixture; the atomizing mechanism comprises a water chamber, the first atomizing ball, the second atomizing ball, an umbrella-shaped atomizer, and a regulating mechanism; the water chamber includes the first and second water inlet and the first and second water outlet; the regulating mechanism adjusts the fit clearance between the first atomizing ball and the first water outlet, the fit clearance between the second atomizing ball and the second water outlet, and the flare angle of the umbrella surface of the umbrella-shaped atomizer. The beneficial effect is: the two-stage atomization—coordinating the atomizing balls and the water outlets, and using an umbrella-shaped atomizer—guarantees the atomizing effect.

Abstract: A system for managing fuel-vapor emission from a fuel tank of a vehicle using a vortex-effect flow separator coupled in the fuel-vapor purging system of the vehicle. The warmer-flow outlet of the separator is coupled to the engine intake, and the cooler-flow outlet is coupled to the fuel tank. In this way, less fuel vapor is delivered to the engine intake.

Abstract: In an air filter for filtering the intake air for internal combustion engines of motor vehicles, with a filter housing, which has an air inlet, an air outlet, and at least one water outlet disposed in the housing bottom, and with a replaceable filter matte disposed in the filter housing between the air intake and air outlet, in order to separate water particles from the intake air and in order to optimally discharge the separated water from the filter housing, a water separator is disposed upstream of the filter matte in the filter housing and means are provided in the at least one water outlet, which produce a water level in the water outlet of such a height that the vacuum in the filter housing acting on the water outlet is compensated for.

Abstract: The invention relates to a method for biological cleaning of a contaminated gas flow containing gaseous and/or particulate contaminants comprising the steps of contacting the contaminated gas flow counter-currently with a jet of suitable microorganism-containing scrubbing liquid in order to enhance absorption of gaseous and particulate contaminants in the scrubbing liquid; recovering the scrubbing liquid in a vessel; draining part of the scrubbing liquid from the vessel and compensating the drained part with fresh liquid. The method is carried out in a reverse jet scrubber and does not use any packing material for support to the microorganisms.

Abstract: A method and apparatus of cooling incinerator exhaust gas for a cleaning treatment of high temperature exhaust gas discharged from an incinerator of refuse and/or waste in a post-step are provided. A spray cooling chamber includes a chamber having a lower end portion formed into a nearly cylindrical shape of an inverted conical shape, a gas distribution chamber equipped with a revolving blade, arranged at an upstream side of the chamber, a sprayer of a cooling liquid arranged at central upper portion of the chamber, a dust exhaust port arranged at the lower end portion of the chamber, and an exhaust pipe arranged on the chamber. Waste heat recovery from exhaust gas is limited to a temperature range capable of suppressing generation of dioxins, and high temperature exhaust gas is rapidly cooled, particularly at a temperature drop rate such that the vicinity of 300.degree. C. is dropped in a short time within 1 second, so that exhaust concentration of dioxins from an incinerator plant can be decreased to 0.

Abstract: A spray tower includes inner and outer tubes arranged coaxial with each other on a common vertical axis. At the lower end of the inner tube is provided a guide cylinder group composed of a plurality of guide cylinders which are arranged coaxially with each other on a common vertical axis. A guide vane is provided under the guide cylinder group. The guide vane is in a shape of inverted truncated cone whose diameter is reduced in a downward direction. Accordingly, gas flowing downward between the inner and outer tubes is uniformly divided under the guide cylinder group by means of the guide vane so that the divided gases flows upward uniformly inside the respective cylinders. A plurality of vertical rectifying plates may be provided to the guide cylinder group so as to extend radially from the vertical axis of the guide cylinder group for reducing pressure loss.
