A membrane process to capture CO2 from power plant flue gas

摘要

Production of power from coal inevitably generates carbon dioxide (CO2) as a by-product. To mitigate global climate change, this CO2 must be captured and sequestered. A number of technologies are being evaluated for CO2 capture. Membrane technology is attractive because of its inherent advantages such as high energy efficiency, a small footprint, environmentally friendly operation (no chemicals), mechanical simplicity, and proven reliability.
