Abstract
Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a direct exchange heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed by directly contacting a heat exchange liquid in the direct contact heat exchanger while the uncondensed light gases from the process stream form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.
