The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...

The presence of H2O in postcombustion gas streams is an important technical issue for deploying CO2-selective adsorbents. Because of its permanent dipole, H2O can interact strongly with materials where the selectivity for CO2 is a consequence of its quadrupole interacting with charges in the material. We performed molecular simulations to model the adsorption of pure H2O and CO2 as well as H2O/...
