Advanced Materials and Process for CO2 Removal from Flue Gas

摘要

ATMI and SRI working in collaboration have developed an innovative new CO2 capture technology that offers promise as a new low-cost route to capture and reuse of CO2 in a variety of industrial and power generation applications. The technology is based on ATMI’s BrightBlack~R family of precision carbon adsorbents and SRI’s innovative adsorption fractionation process, which is based on continuous adsorbent recycle. The system is designed to take advantage of the recoveries and purities achievable with countercurrent separations processes while minimizing power requirements associated with pressure drop and adsorbent regeneration. The ATMI-SRI CO2 capture system has been demonstrated in small lab and field pilots with flue gas feed streams ranging in CO2 content from 4% to 15%, successfully achieving greater than 90% recovery and 99% CO2 purity. A larger field pilot is under construction at the National Carbon Capture Center and will be ready for testing in 2013.
