Abstract:
The present techniques are directed to a system and method for recovering carbon dioxide (CO 2 ). The method includes recovering the CO 2  from a gas mixture including the CO 2  via a CO 2  separation system. The CO 2  separation system includes a rotating freezer/melter.

Claim (Index 1):
A method for recovering carbon dioxide (CO 2 ), comprising:\n receiving, in a CO 2  separation system, a gas mixture from a power plant, wherein the gas mixture comprises CO 2 , and the CO 2  separation system comprises:\n a rotating freezer/melter having a freezing zone, a melting zone, and a rotor; \n a CO 2  separation device downstream of the freezing zone of the rotating freezer/melter; and \n a compressor downstream of the CO 2  separation device; \n flowing the gas mixture through the rotor while the rotor is in the freezing zone; capturing solid CO 2  from the gas mixture on the rotor while the rotor is in the freezing zone; melting the solid CO 2  captured on the rotor while the rotor is in the melting zone, thereby forming liquid CO 2 ; flowing the liquid CO 2  through the rotor while the rotor is in the melting zone; maintaining the melting zone at a higher pressure than the freezing zone to preserve the melted CO 2  in a liquid state as it exits the melting zone; routing the remaining gas mixture out of the freezing zone and into the CO 2  separation device; recovering residual CO 2  from the remaining gas mixture using the CO 2  separation device; pressurizing the residual CO 2  using the compressor to produce a pressurized CO 2  vapor stream; and using the pressurized CO 2  vapor stream to melt the solid CO 2  within the melting zone of the rotating freezer/melter.
