SYSTEMS AND METHODS FOR TREATING CARBON DIOXIDE

摘要

A heat exchange assembly for treating carbon dioxide (CO2) is described. The heat exchange assembly includes a housing that includes an inlet, an outlet, and an inner surface that defines a cavity extending between the inlet and the outlet. The housing is configured to receive solid CO2 through the inlet. At least one heat exchange tube extends through the housing. The heat exchange tube is oriented to contact solid CO2 to facilitate transferring heat from solid CO2 to a heat exchanger fluid being channeled through the heat exchange tube to facilitate converting at least a portion of solid CO2 into liquid CO2. The heat exchange assembly is configured to recover a refrigeration value from the solid CO2 and transfer at least a portion of the recovered refrigeration value to a flue gas.
