  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • 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 ...

  • Development and Application of Biological H2S Scrubbers for Treatment of Digester Gas

    ABSTRACTAs part of the California Energy Group (Former California Energy Commission) Public Interest Energy Research (PIER) Program, biological hydrogen sulfide (H2S) biogas cleaning was evaluated. The biological H2S scrubber uses bacteria to oxidize the sulfide to produce both elementary sulfur and sulfuric acid. This system was tested at the Inland Empire Utilities Agency’s Regional Plant 1 ...

  • Coke Plant Scrubber Water Case Study

    Challenge For the production of coke, volatile constituents of the coal —including water, coal-gas, and coal-tar— are driven off by baking in an airless furnace at temperatures as high as 2.000 °C. The flue gas goes through an ammonia-based scrubbing process. The resulting scrubber water contain small coal-tar and other organic particles (1-250 micron) that cause scaling in ...

  • Hydrogen Sulfide Scrubber Systems in Hydrometallurgical Application

    Hydrogen Sulfide is a highly toxic and flammable gas. Being heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell, so potential victims may be unaware of its presence until it is too late. The lethal concentration for 50% of humans is 800ppm for 5 minutes of exposure. H2S is a by-product in many ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • Using Venturi Scrubber Technology for Syngas Cleaning

    As part of our nation's program to reduce dependence on fossil fuels, various gasification technologies are being applied. These processes take renewable organic material and, through the application of heat and pressure, convert the materials into syngas for further use. Arguably, in nearly all of these processes, the most critical design aspect is the reliable and efficient removal of ...

  • 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 ...

  • More to Scrubber Pumps than Meets the Eye

    One component, in particular, needs to be carefully selected to ensure safe and efficient sulphur removal. The time is now Shipowners are having to move fast to change fuel type to distillate fuel or LNG, or to install the exhaust gas cleaning systems (EGC systems) known as scrubbers. They’re reacting to new sulphur emission legislation set to come into force in designated ...

  • Tri-NOx Multi-Chem Wet Scrubber. Case Study of Our NOx Scrubber in a Plastics Resin Plant.

    As part of a commitment to reduce airborne emissions – or even the threat of such emissions – the Mt. Vernon, IN plant of GE Plastics has installed a NOx scrubber. When such GE Plastics products as Ultem resins are produced, nitric acid is used, and emissions from this step are tightly controlled. But to address upset conditions, the company opted to install an emergency scrubber that can treat ...

  • Operating experience on the treatment on fgd scrubber blowdown from existing generating stations

    Amendments to the original 1990 Clean Air Act resulted in the initial SO2 control requirements for coalfired power plants in the mid1990’s. These amendments initiated a new phase of installation of Flue Gas Desulfurization (FGD) scrubbers in the United States. The Clean Air Interstate Rules (CAIR), first filed by the EPA in 2004, required that more stringent requirements for SO2 and NOx emission ...
