  • Downstream sulfuric acid plants benefit from WESP technology

    Industrial-grade sulfuric acid, still the most widely used industrial chemical in the world, continues to be sourced primarily (about 70 percent) as a nondiscretionary byproduct from the roasting, smelting, and refining of nonferrous metals. The rest comes from natural gas processing, electric power generation, and spent acid regeneration. These industries are usually heavy emitters of ...

  • A 2-D meteorological pre-processor for real-time 3-D ATD models

    Horizontal non-uniformity has important effects on the structure of the atmospheric boundary layer and, consequently, on pollutant transport and dispersion. These effects can be dominant in coastal sites or in the presence of complex terrain. Advanced 3-D atmospheric dispersion models can be used to calculate short-term pollutant concentrations in such complex situations. The use of new ...

  • Who Needs Continuous Emissions Monitoring?

    Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. ...
