摘要

Postcombustion CO_2 capture (PCCC) technology has the potential to contribute significantly to the reduction of anthropogenic CO_2 emissions. The application of PCCC technology to reduce CO_2 emissions at large point sources, such as fossil fuel-fired power plants is particularly promising. Amine-based scrubbing is the most mature PCCC technology, with 2-aminoethanol (MEA) the most widely utilized solvent. Despite the use of water wash systems to treat effluent, small amounts of the solvent and degradation products are present in amine-based PCCC plant emissions. Recently, concerns have arisen that emissions from PCCC plants could be harmful to human health and the environment.Of particular interest are nitrosamine and nitramine degradation products, many of which are known carcinogens.
