  • Monitoring of Hydrogen Sulfide in Industrial Processes

    Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

  • Natural Gas Processing Case Study

    The Customer The Company is an exploration and production company that builds natural gas reserves through the acquisition and development of oil and gas assets across the U.S. They are one of the largest producers of natural gas in the Nation. The Process The Company uses multiple scrubbers to clean out the impurities of the natural gas that they ...

  • 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 ...

  • Food Processing: Tower Scrubber Reduces Pollutants Recovering Reusable Solvents Case Study

    FMC adapted a ‘good neighbor’ policy when it installed a specialized, countercurrent packed tower scrubber into its seaweed extraction process system. The tower recovers isopropyl alcohol from the company’s process, thereby reducing pollutant emissions at the Rockland, Maine facility. The unit rids of the need for additional pollution control instrumentation and eliminates ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

  • 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 ...

  • 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 ...
