| abstract |
Systems and methods for the purification of carbon dioxide are provided. Also described are systems and methods of efficiently producing power using novel heat integration techniques, while producing carbon dioxide that is sufficiently pure to be sequestered. In some embodiments, a carbon dioxide-containing fluid stream is purified by removing NO x and SO x , using a single reactive absorption column. A carbon dioxide-containing fluid stream can be purified by removing one or more other contaminants (e.g., a non-condensable gas), in some instances. |
