  • 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 ...

  • 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 ...

  • Heavy metals in wet scrubber residue from a medium–sized (32 MW) municipal district heating plant incinerating wood and peat in a fluidised bed boiler

    Due to the low total concentrations of heavy metals and extractable compounds, it is recommended that the wet scrubber residue be used as a construction agent instead of being disposed of in landfills. According to five–stage sequential extraction, the highest concentrations of most of the heavy metals occurred in the residual fraction (i.e., HF + HNO3 + HCl), which means that ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • 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 ...
