Technology Overview

Carbon Capture-Ready Multi-Pollutant Control and Carbon Capture Solutions to Meet Requirements Today and in the Future


Powerspan offers advanced, air pollution control solutions for existing and new coal-fired power plants and large, industrial applications that rely on coal for their operation or electricity generation. Our solutions offer lower cost, higher performance, and are aimed at future requirements, not those of the past.

We provide proprietary multi-pollutant control technology, with or without nitrogen oxide (NOX) control, and carbon dioxide (CO2) capture technology with the following solutions:

Key advantages of our ECO and ECO-SO2 multi-pollutant control solutions are:

  • Reduced cost
  • Higher performance
  • Reduced water usage
  • Produces valuable fertilizer co-product that is sold in agricultural markets, instead of flue gas desulfurization waste requiring landfill disposal
  • Potential to add our CO2 capture system when needed

Key advantages of our ECO2 carbon dioxide capture process are:

  • Suitability for existing and new pulverized coal-fired power plants
  • Can be installed following conventional SO2 scrubbing technology, such as a limestone forced-oxidation SO2 scrubber, or following Powerspan’s ECO or ECO-SO2 multi-pollutant control technologies
  • 90% capture
  • Reduced cost
  • Reduced energy requirements
  • Generates pipeline quality CO2
  • ECO2 process and equipment have been successfully demonstrated on an existing coal-fired power plant, one of the few technologies to have achieved this significant milestone

At Powerspan we invest considerably in Research and Development, and we work in close collaboration with our customers to ensure our development efforts result in scalable, reliable, cost-effective solutions.
