Carbon Dioxide Capture from Large Point Sources

76045-The capture of carbon dioxide at the source of its emission has been a major focus in greenhouse gas emission control. Solutions must be both compact and economic, and also address the removal of other acid gases from natural gas streams. Current technologies used for capturing CO2 suffer from inefficient mass transfer and economics. This project will develop a stable, membrane-based, CO2 removal system from flue gas streams that originate from large point sources. The system will have improved mass transfer rates compared to conventional technologies. Phase I will demonstrate that the membrane-based absorption system can provide superior carbon dioxide removal from simulated power plant flue gas. The stability of the membrane system will be shown for various operating conditions and chemical environments. Commercial Applications and Other Benefits as described by the awardee: The technology should have broad application for the removal of acid gases (such as carbon dioxide, hydrogen sulfide and sulfur dioxide) and water vapor from various gas streams, such as those in natural gas production, power generation, etc.
