Henry's Law Constants and Vapor-Liquid Distribution Coefficients of Noncondensable Gases Dissolved in Carbon Dioxide.

The accurate determination of the solubilities of the typical impurity gases present in captured CO in the carbon capture, utilization, and storage chain is an essential prerequisite for the successful modeling of the CO stream thermodynamic properties. In this paper, Henry's law constants and the vapor-liquid distribution coefficients of six noncondensable gases, namely, N, O, H, CH, Ar, and CO, at infinite dilution in liquid CO are derived based on published vapor-liquid equilibrium data at temperatures ranging from the triple point (216.59 K) to the critical point (304.
