  • NOx Scrubbing Technology Breakthrough

    Pacific Rim Design and Development and Dupont are proud to introduce a technology breakthrough in the treatment and safe elimination of problematic nitric oxide (NO) and nitrogen dioxide (NO2 ).  There are six forms of nitrogen oxide (NOx); the drawings to the right show the two most problematic forms.  These two are of particular interest because they are identified as atmospheric ...


  • Chemical Aspects of NOX Scrubbing

    With the passage of the 1990 Clean Air Act Amendments, many chemical and metal industries and utility producers will now be required to further limit the amount of NOX (Nitrogen Oxides) produced. NOX is a precursor to ozone in the atmosphere, and is believed to be a major contributor to acidic deposition (acid rain). Formation of ozone: NO2 + Hv ...

  • Wet Scrubbing HCL & SiCl4 Fumes

    This two-stage scrubbing system utilizes a jet venturi scrubber in conjunction with a counter current packed tower including entrainment mist eliminator. It was designed to eliminate the HC1 (hydrochloric acid) fumes generated when S1C14 (silicon tetrachioride) comes in contact with moisture cluring processing operations at a zirconium processing tank farrn, and also the remaining smail amount of ...


  • Pharmaceutical Gas Scrubbing - Case Study

    Application Novartis Ringaskiddy Limited needed to scrub a variety of aggressive acid and volatile organic compounds from the vents of pharmaceutical batch reactors. These make up part of the manufacturing process of a range of pharmaceutical ingredients. The compounds included HCl and methyl bromide fumes within air or nitrogen streams. System description ...

  • CANSOLV® SULFUR DIOXIDE SCRUBBING SYSTEM

    The CANSOLV® System scrubbing technology is the leading regenerable SO2 scrubbing process. It uses an aqueous amine solvent in a conventional amine treater process flowsheet configuration to achieve high-efficiency removal of SO2 from a ...

  • Scrubber Removes Grease and Particulates from Air Exhaust

    Operating Issue A food-industry leader in Alabama operates several pork-sausage cookers that exhaust over 4,000 ACFM of moisture and pork grease. The operator installed Electrostatic Precipitators (ESPs) to treat the exhaust but these systems performed poorly and generated high maintenance and operating costs. Additionally, these systems were antiquated and required significant capital ...

  • Dry Air Scrubber for Propylene Oxide

    Background For decades, Advanced Air Technologies, Inc. has been the leader in air scrubber  technology for abatement of Ethylene Oxide (EtO) emissions.   In fact, AAT, Inc. was founded in 1987 on a unique dry scrubbing, chemi-sorption process for EtO.  The result is a series of fixed bed “Safe-Cell II” dry scrubbers, consisting of the DR-490, DR-50, and ...

  • Shipping Emissions - The Environmental Case for Sea Water Scrubbing

    The romantic image of a luxury liner cruising blue seas amid blue skies and trailing a plume of smoke is too close to the truth for comfort. The emissions from shipping make an increasingly conspicuous contribution to air quality, health and environmental problems of Europe, and indeed, the world. Yet an effective and safe technology to dramatically reduce these emissions is being discouraged, ...


  • Nitrification processes in scrubbing liquid of an exhaust air treatment system of a large-scale pig housing facility

    The use of multi-staged exhaust air treatment systems is an effective method of substantially reducing the emission of ammonia, dust particles and odorous substances. Wet filter walls are able to absorb large amounts of ammonia when scrubbing fluid containing sulphuric acid is used. In addition, due to their large surface areas and the permanent supply of oxygen and nutrients, wet filter walls ...

  • Multiple stage scrubbing and adsorption system for Incinerator exhaust at an industrial waste processing plant

    Challenge Monroe Environmental was called upon to purify a 20,000 CFM exhaust stream that was being discharged from an industrial waste incinerator at 2000° F. The pollutants that needed to be removed were: Fine Ash Particulate HCL Gas Mercury Dioxins The combination of soluble and solid pollutants, coupled with the ...

  • A breath of fresh air - Wet scrubbing eliminates odors associated with processing discarded liquid from cheese manufacturing

    When International Ingredient Corp.’s drying plant in Monroe, WI, opened in 1994, it was the first plant designed specifically for large-scale drum drying of dairy products for the feed industry. At that time, its only neighbor was a cheese producer. International Ingredient used a land spread technique to process the discarded liquids resulting from its neighbor’s cheese ...

  • Monroe Scrubbing System provides halide recovery at a major glass products plant

    Challenge A glass manufacturing plant was having trouble cleaning the emitted gases, particulate, and odors that resulted from its manufacturing process. Metallic Halides such as SnCl4 and TiCl4 were being applied to hot glass to impart special properties. The halide and oxide emissions were hazardous, extremely pungent, irritating in odor, and very difficult to scrub. ...

  • Ammonia Emergency Plan Calls on Packed Tower to Scrub Released Chemicals,

    A few years ago Union Camp turned a corner.  Management decided that advance planning would take the place of reacting after the fact to an emergency or regulatory agency demands.  At Union Camp’s Dover, OH. facility, byproducts of the paper industry are converted into usable specialty chemicals for cosmetics, adhesives and other industries. Crystallization is a process used intensively ...
