  • The Jet Venturi Scrubber and Other CR Clean Wet Scrubbers

  • CR Clean Air - Model FS71 - Jet Venturi Fume Scrubbers

    CR Clean Air - Model FS71 - Jet Venturi Fume Scrubbers

    The Clean Air, LLC Jet-Venturi Fume Scrubber is a dependable device designed to entrain and scrub large volumes of gases without the use of complicated baffles or moving parts. Motivating fluid, generally water, leaves the nozzle in a hollow cone spray, creating a draft which draws the gases and vapors into the moving stream where they are continuously scrubbed or absorbed. Subsequent separation is accomplished in units specifically designed to meet...

  • CR Clean Air - Packed Tower Scrubber

    CR Clean Air - Packed Tower Scrubber

    The Clean Air Group, LLC’s Packed Tower Scrubber utilizes a vertical countercurrent design for highly efficient absorption of a variety of toxic gases. In addition to its extensive use in air pollution control, the Packed Tower can serve as a gas/liquid contactor in a number of process applications. Efficiencies of 99.99% and greater are not unusual for many scrubbing applications. During operation, gas flows upward through a packed bed while...

  • CR Clean Air - Model HE75 - High Energy Venturi Fume Scrubbers

    CR Clean Air - Model HE75 - High Energy Venturi Fume Scrubbers

    The High Energy Venturi Scrubber is ideally suited to the capture of small particles less than 3 microns in size. It is effective as well in the submicron range and requires little or no maintenance. For applications where variations in gas flow require throat gas velocity compensation to maintain specified scrubbing efficiencies, the Clean Air Group, LLC offers automatic and manually variable throat designs. The automatic throat is used where flow...

  • CR Clean Air - Model 96MCBS - Multi-Channel Bed Scrubber (MCBS)

    CR Clean Air - Model 96MCBS - Multi-Channel Bed Scrubber (MCBS)

    The Clean AIr Group, LLC Multi-Channel Bed Scrubber (MCBS) is designed to collect particles above 2 microns with 99°/o efficiency. The MCBS system utilizes a turbulent layer of liquid, air, bubbles and mist for 99°/o scrubbing efficiency of S02, HCI, gas cooling and odor control. Continuous self-cleaning eliminates clogging, even with tar mist.

  • CR Clean Air - Model NOX08E - NOx Fume Scrubbers

    CR Clean Air - Model NOX08E - NOx Fume Scrubbers

    Creative Approaches To Cleaning And Purifying Air: The Clean AIr Group’s NOx Scrubbers provide the highest removal efficiency available for NOx. Efficiencies of 90% as measured by EPA Method 7, are guaranteed with many on-line systems operating at efficiencies exceeding 99%.

  • Acidic Gases

    Acidic Gases

    Bromine and Fluorine: Bromine (Br2) and Fluorine (F2) are typically scrubbed in a counter current packed tower to achieve maximum efficiencies using a dilute aqueous alkali solution. For applications with very high concentrations of these gases it may be useful to use a Jet Venturi Fume Scrubber as a first stage to remove the bulk of the contaminant then “polish” with a packed tower scrubber. With respect to F2, the...

  • Ammonia/Amines

    Ammonia/Amines

    Ammonia (NH3) is readily scrubbed using Jet Venturi, Packed Towers, or Multi-channel Bed Scrubbers. Although ammonia is infinitely soluble in water, recirculating an aqueous NH3 solution cannot generally be used for scrubbing. Aqueous NH3 solutions are characterized by relatively high NH3 vapor pressures that prevent the mass transfer of NH3 from gas to liquid phase. Commonly NH3 is scrubbed with an aqueous acid solution. Sulfuric acid or...

  • Ethylene Oxide

    Ethylene Oxide

    Ethylene Oxide (EO or EtO) and Propylene Oxide (PO) are utilized as sterilants for medical products and food products as well as in the manufacture of chemical products such as surfactants. Although both compounds are readily soluble in water and, in fact, hydrolyze to form ethylene and propylene glycol the removal of these compounds is not a simple matter.

  • Mercury

    Mercury

    Mercury in flue gas exists as gas-phase elemental mercury (HgO) and oxidized or ionic form of mercury, such as mercuric chloride, HgCl2 (HgII+) or mercuric oxide (HgO). Speciation (oxidation state) of the mercury influences the effectiveness of various control technologies and whether the mercury is deposited locally or transported over long distances. Emissions of elemental mercury, for example, can remain in the atmosphere for about a year and be...

  • Particulate Matter

    Particulate Matter

    Includes dust, dirt, soot, smoke and liquid droplets directly emitted into the air by sources such as factories, power plants, cars, construction activity, fires and natural windblown dust. Particles formed in the atmosphere by condensation or the transformation of emitted gases such as SO2 and VOCs are also considered particulate matter. PM is usually divided up into different classes based on size, ranging from total suspended matter (TSP) to PM-10...

  • Sulfides/Mercaptans

    Sulfides/Mercaptans

    H2S: Hydrogen Sulfide is most often found in the off-gases from Waste Water Treatment plants and certain Pulp and Paper processes (here along with other TRS-total reduced sulfur- compounds), Hydrogen Sulfide reacts readily with aqueous NaOH but often aqueous NaOH alone is not the preferred choice for scrubbing.
