Thermodynamic Analysis of Post-combustion Inertial CO2 Extraction System

The Inertial CO2 Extraction System (ICES) represents a novel method of capturing CO2 from flue gas. ICES makes use of the cooling effect of supersonic expansion to cool the flue gas stream, causing CO2 in the flue gas to change phase to form a solid that can then be captured from the gas stream through an inertial separation. A first-principles thermodynamic analysis of this unique process is described and results of the analysis are reported.
