  • 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 ...

  • 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 ...


  • Flux force condensation scrubbing

    Flux force condensation scrubbing technology is used to capture fine (submicron) particulate at extremely high efficiency. It is a preferred method when using wet scrubbing to collect and control dioxins from combustion sources. As an added benefit, through the use of condensation, the water vapor plume commonly associated with a wet scrubbing system can be effectively eliminated. The overall ...

  • 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 ...


  • Alcohol scrubbing pharmaceutical manufacturing 105

    A New York based pharmaceutical manufacturer’s pill coating operation required ventilation to keep the isopropanol levels in the dryers from reaching LEL concentrations. Due to the high volatility of the alcohol, it was necessary to use a once through with water to absorb the hot, high concentrations of isopropanol. A vertical tray scrubber (Model VTS) was utilized in order to optimize the ...

  • 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 ...

  • The Phase 1 Environmental Assessment

    In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Los Angeles County WRRF Embraces Codigestion

    Technology to produce food waste slurry key to project implementation - and helps generators comply with California organics recycling mandates. The Sanitation Districts’ JWPCP in Carson (CA) treats an average of 280 million gallons/day of wastewater. One of the two anaerobic digestion tanks above has been used for codigestion, with the second serving as the control. Photos ...

  • Application Data for Dry-Scrubbing Media in Collection Systems

    Abstract Dry-scrubbing systems have been used for many years to control odors in wastewater applications. The systems have ranged in size from larger multiple bed scrubbers for force mains and large pump station applications to smaller single bed systems and modular systems in small wet wells, motor control centers, and other areas. Two reasons for their continued use are simplicity of ...

  • 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, ...


  • SULFURIC ACID PLANT TAIL GAS CLEANUP WITH CANSOLV“ SYSTEM SO2 SCRUBBING TECHNOLOGY

    The tail gas from a single absorption sulfuric acid plant typically contains 2000-3000 ppmv of unreacted SO2. Emission regulations for new plants in most jurisdictions today require cleanup of this stream prior to discharge into the atmosphere and many grandfathered units are being required to decrease emission levels. The current paradigm is to add a second stage of conversion, which reduces the ...

  • Chemical Industry: Wet Scrubbing HCL & SiCl4 Fumes Case Study

    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 HCl (hydrochloric acid) fumes generated when SiC14 (silicon tetrachloride) comes in contact with moisture during processing operations at a zirconium processing tank farm, and also the remaining small amount of ...

    Over the past five years, the CANSOLV® system SO2 scrubbing technology has moved from the status of an emerging technology to that of a commercially ...

  • Making pressurized water scrubbing the ultimate biogas upgrading technology with the DMT Carborex® PWS system.

    Abstract Biogas is one of the most promising energy sources for the future. Biogas is a “waste” product from e.g. landfill sites or digesters that can be applied as a green and renewable energy source with no global emissions on CO2 and hardly no local emissions on other pollutants. Currently most biogas is used at a CHP at which a large part of the energy ...

  • A chemo-biological treatment of scrubbing water from power plants with recovery of value-added products

    A chemo-biological approach for treating sulphate-rich effluent generated during wet scrubbing of flue gas emissions from fossil fuel fired power plants has been discussed. Microbial sulphate reduction was carried out in an anaerobic up-flow packed bed bioreactor (R1) using ethanol as carbon source. More than 90% of Total Equivalent Sulphate (TES) present in the effluent was reduced to sulphide ...

  • Comparing the Performance of Recirculating Cyclones Applied to the Dry Scrubbing of Gaseous HCI with Hydrated Lime

    Recirculating cyclone systems, combining a numerically optimized reverse flow gas cyclone (RS_VHE geometry) with a straight-through cyclone concentrator, were employed as reaction chambers for the dry scrubbing of gaseous hydrogen chloride with solid hydrated lime particles. The performance of this technology was tested at laboratory scale with two differently sized RS_VHE cyclones (0.020 ...
