  • 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 ...

  • 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 ...

  • 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 ...

  • Power Industry: Noxious Fumes at TVA Handled by Scrubber Case Study

    To keep the work area free of noxious fumes and reduce atmosphere pollution, T.V.A. Wilson Dam uses a 36″ diameter Clean Air Group fume scrubber to handle 12,500 cfm of gas @ 150°F in their high-analysis super phosphate operations. Manufacturing high analysis super phosphate fertilizer at the TVA Wilson Dam operation creates noxious fumes. Most of these fumes are liberated during the ...

  • Cross-flow scrubber design case study from Kimre

    Cross-flow or, Horizontal-flow scrubber design is almost never mentioned in chemical engineering literature. Textbooks (1) used at universities for future engineers, undergraduate as well as graduate level students, invariably only discuss counter-current vertical scrubber tower design. Likewise, professional reference texts (2) generally provide little or no mention of horizontal cross-flow ...
