correlation of co2 solubility in [bmim][c(cn)3] ionic liquid utilizing a modified form of srk eos

A modified form of the well-known srk eos (msrk eos), was employed to correlate co2 solubility in ionic liquid 1-butyl-3-methylimidazolium tricyanomethane ([bmim][c(cn)3])# this eos was developed by shiflett and yokozeki (fluid phase equilibria 294, 105–113 (2010)) to model the il-containing systems# there exist four adjustable parameters for pure components in addition to five binary interaction coefficients in this model# in the present work, the “modified lydersen-joback-reid” method was also implemented to estimate the physical properties of [bmim][c(cn)3]#the results show the excellent performance of the model to correlate co2 solubility in [bmim][c(cn)3] so that the overall aad% equal to 1#86 obtained#
