Abstract
Improved processes and systems for removing COfrom exhaust gas to substantially prevent such greenhouse gas from being released to the atmosphere. The systems and processes use a) staged cooling of an exhaust gas stream, b) addition of an antifreeze, and c) a combination of non-scraped heat exchangers and scraped heat exchangers to separate COfrom an exhaust stream while reducing or minimizing accumulation of ice on surfaces within the system.
