The pre-scrubber system includes a first outlet for discharging a pre-scrubbed vent stream and a second outlet for discharging a discharge stream of pre-scrubber fluid.

Abstract: A method is described for treating a gas stream containing a flammable gas, such as hydrogen or a hydrocarbon gas. The gas stream is conveyed to a liquid ring pump (18), to which a gaseous oxidant and water are supplied. The water and the gas stream are discharged from the pump (18), with the discharged gas stream being subsequently separated from the liquid, and conveyed to a pyrolysis device (42) for pyrolysing the flammable gas and the oxidant. Any particulates and acidic species within the gas stream are retained by the water within the liquid ring pump to inhibit corrosion or blockage of the pyrolysis device (42). A filter or other device (40) may be provided to remove water from the gas stream before it enters the pyrolysis device (42).

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: An air scrubber for removing oils and contaminates from air has an underside inlet for the introduction of contaminated air. The contaminated air passes through a reduced aperture passageway which prevents retrograde flow of contaminates or cleaning fluids contained in the scrubber. The contaminated air is thereafter directed upwards through a scrub reservoir having a plurality of apertures, such that the contaminated air passing through the apertures forms jets which cause interaction between the cleaning fluid and the contaminates, thereby creating droplets containing cleaning fluid with entrapped contaminates, and cleaned air. The droplets and air are directed to a mist eliminator having a plurality of chevron V structures which capture the droplets and return them to the main reservoir. A circulating pump moves cleaning fluid from the main reservoir to an upper reservoir which spills into the cleaning reservoir.

Abstract: A gas flow system and method are provided for controlling the moisture in a gas flow. The system may include a gas source from which gas flows, a processing chamber to which the gas flows, and a gas flow line through which the gas flows from the gas source to the processing chamber. The gas flow line may include a moisture control line section. The moisture control line section includes a pass-through line through which the gas may pass, so as to be exposed to a dryer. The exposure to a dryer may be controlled by a suitable valve. A scrubber is disposed in the gas flow line, the scrubber removing contaminates from the gas in the gas flow. The system may include a moisture sensor disposed in the gas flow, the moisture sensor sensing at least one parameter of the gas and outputting a signal representing the at least parameter to a moisture sensor controller, such that the moisture sensor controller determines the moisture in the gas.

Abstract: A system is disclosed for condensation particle counting in conjunction with modifying an aerosol to enhance the formation and growth of droplets of a selected working fluid, preferably water. Before saturation with the working fluid, the aerosol is exposed to an aerosol modifying component, preferably a vapor including molecules that are adsorbed onto surfaces of the particles or other elements suspended in the aerosol. Adsorption alters the surface character of the suspended elements towards increased affinity for the vapor of the working fluid, to promote the formation and growth of working fluid droplets. The droplets are optically detected to indicate numbers and concentrations of the suspended elements.

Abstract: An ion exchange scrubber has a housing, and a partition plate installed within the housing. The partition plate partitions an inner space of the housing in longitudinal direction into two chambers that are filled with a predetermined amount of aqueous solution. The upper end portions of the two partitioned chambers communicate with each other. At least one cartridge is installed at the upper portion and has an ion exchange resin. The ion exchange resin removes a harmful substance contained in the gas. By repeatedly pumping the aqueous solution from one side chamber to the other side chamber, and immersing and cleaning the contaminated ion exchange resin in the aqueous solution, the contaminated gas can be effectively processed even with a small amount of water.

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 gas-liquid contactor is provided for removing gases and particulate matter from flue gases, such as those which are produced by processing operations of the type carried out in utility and industrial facilities. The gas-liquid contactor includes a tower into which a slurry is introduced for absorbing gases and particulate matter, and is configured so as to eliminate the requirement for a pump to deliver the slurry to the tower. In addition, the tower is configured to accommodate a maximum flue gas flow velocity through the tower while maintaining proper operation of the tower. Liquid particles in which the gases and particulate matter are entrained are collected in a tank, through which the slurry is recycled to the tower. The level of the slurry within the tank is higher than the entry point of the slurry into the tower, such that the slurry returns to the tower under the force of gravity.
