  • 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 ...

  • Controlling Stack Emissions in the Wood Products Industry & Wood Fired Boilers

    Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

  • Precipitator Solves Dryer Problem

    Plum Creek Manufacturing, Columbia Falls, Montana, installed a PPC Industries electrostatic precipitator to solve a direct fired dryer dust plugging problem. The electrostatic precipitator was installed in a very congested area and the project had to be done so the dryer was off-line a minimal amount of time. Plum Creek personnel relocated existing equipment, poured concrete footings, ran all of ...

  • 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 ...

  • Innovative wet electrostatic precipitators assure competitive edge in acid marketplace

    The unsteady global economic recovery continues to subject many core industries to persistent volatility in profits, prices, markets and capital investments. However, some analysts remain optimistic about the global international trade in sulfur in all forms, particularly sulfuric acid. This versatile mineral acid is both the world’s most widely used chemical, and the one with the highest ...

  • Multi-pollutant control creates fuel options for whiskey distillery

    The distillation of fine whiskey requires the application of appropriate amounts of heat in the form of steam. The generation of that steam can come from multiple sources of energy. The Wild Turkey Distillery located in Lawrenceburg, KY has utilized an EISENMANN Wet Electrostatic Precipitator Dual Field (WESP- 2F) to provide multi-pollutant air pollution control on the plants new biomass fired ...

  • CFD modelling of electrohydrodynamic gas flow in an electrostatic precipitator

    Modelling of the flow velocity fields for electrohydrodynamic flow in a wire-to-plate type electrostatic precipitator was achieved. From calculations for the flow employing different flow models, the Chen-Kim k − ε turbulent model appeared to be the most appropriate choice to obtain a quantitative image of the resulting mean flow field and downstream wake flow of the rear wire, although this was ...

  • Suppression of particle deposition onto downstream wall in an AC Electrostatic Precipitator with neutralisation

    Electrostatic Precipitators (ESPs) are used to decontaminate polluted environment around the tunnels. A conventional ESP has high collection efficiency but still has a problem in that its downstream walls are polluted due to particle deposition. The experiments carried out in this study have focused on how the particle deposition can be prevented by neutralising the gases. The collection ...

  • The design of electrostatic precipitators by use of physical models

    This paper describes how physical models can be successfully employed in the design of Electrostatic Precipitators (ESP). The development of the computational power of personal computers has made possible the development of mathematical models of complex systems, like ESP, that can be used at relatively low cost. These mathematical models simulate the non linear coupling of the different physical ...
