Mitigation of the effects of climate change is among the greatest challenges of our day. One of the promising tools for managing greenhouse gas emissions is the post-combustion capture and sequestration of CO2 from the flue gas of power plants and industrial processes. Cryogenic capture is a potential technology for realizing the post-combustion capture of CO2. A novel method of implementing a cryogenic CO2 capture system is described that utilizes a multi-phase condensing turbine expansion to cool the flue gas to approximately -150C causing the CO2 to condense as solid dry ice. This solid CO2 can be mechanically separated from the remaining uncondensed flue gas and sent for sequestration. The innovative cooling process through turbine expansion overcomes a key challenge with previous cryogenic CO2 capture solutions in that it does not require condensation within a heat exchanger thus avoiding critical challenges with the buildup of dry ice.
