the hypothesis of "instantaneous molecule cluster" is used to predict the VLE in CO2 absorption using alkanes. It is shown that the predicted values are consistent well with the experimental values in literature
with the linear correlation coefficient larger than 0.95. The results also reveal that the effect of homogenous instantaneous molecule cluster among alkane molecules is the key factor and is more significant than that of homogenous instantaneous molecule cluster among CO2 molecules and that of heterogeneous instantaneous molecule cluster between solvent and CO2 molecules. As carbon chain elongates
formation probability and stability of instantaneous molecule cluster decreases
and absorption capacity increases. The effects of parameters on VLE and their best ranges are also discussed.
