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:
- ECO® (Electro-Catalytic Oxidation) — Multi-pollutant control system for coal-fired power plants (NOX, SO2, oxidized mercury, and fine particulate matter)
- ECO-SO2 — Sulfur dioxide (SO2) scrubber, including oxidized mercury and fine particulate matter control
- ECO2® — CO2 control in conjunction with ECO, ECO-SO2, or other air pollution control system.
Key advantages of our ECO and ECO-SO2 multi-pollutant control solutions are:
- Reduced cost
- Higher performance
- Reduced water usage
- Produce 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
- 90% capture
- Reduced cost
- Reduced energy requirements
- Regenerative process; does not consume ammonia
- Generates pipeline quality CO2; no separate byproduct created
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.
