ATMI Commercializes Innovative Carbon Dioxide Capture System

By G.P. ThomasJun 30 2012

ATMI, a provider of specialty semiconductor materials and high-purity materials handling and delivery solutions, announced that it has begun the commercialization of an innovative carbon dioxide (CO₂) capture system that has been co-developed with SRI International, a nonprofit research and development institute.

Based on a marketing deal, ATMI will lead the commercialization activities and is presently engaging potential partners for rapid development and commercial deployment of capture systems. The system can be employed at natural gas-fired or coal power plants.

The CO₂ capture system includes SRI-designed adsorbent-based gas separation technology and BrightBlack carbon adsorbent technology from ATMI. The unique system demonstrates outstanding performance in CO₂ capture. Field, pilot and lab tests revealed that BrightBlack carbon adsorbents exhibit excellent physical adsorption properties for CO₂ and also display low regeneration energy and high capacity. In addition, the adsorbents show exceptional chemical and mechanical stability in a SRI process that includes a recirculating adsorbent system and integrated CO₂ adsorption and steam-stripping segments. The integrated system has reliably illustrated CO₂ capture efficiencies of more than 90% with high CO₂ purities close to 99%.

Josh Sweeney from ATMI noted that the first commercialization of the combined system is expected to come from small-scale, industrial clients, who want to capture and reuse carbon dioxide in their processes to decrease their CO₂ footprint and raw materials costs. Recently, a small-scale field testing was made using the system and the results will be presented at the NETL CO₂ Capture Technology Meeting, which is to be held on July 9, 2012 in Pittsburgh.
