Prediction of Excess Gibbs Free Energy for a New Working Pair CO2-[emim][Tf2N] in Absorption Refrigeration
In view of the defects of traditional working pairs such as ammonia system, water system and Freon system,a new working pair, CO2-[emim][Tf2N], was proposed for the absorption refrigeration cycle. PR equation of state, NRTL model, and WS mixing rule which was obtained from cubic equation and the exc...

| description | In view of the defects of traditional working pairs such as ammonia system, water system and Freon system,a new working pair, CO2-[emim][Tf2N], was proposed for the absorption refrigeration cycle. PR equation of state, NRTL model, and WS mixing rule which was obtained from cubic equation and the excess free energy model were utilized to develop GE-EOS thermodynamic model in the paper. The excess Gibbs free energy of binary mixture solution under high pressure and high temperature were obtained with the model. The results showed that the excess Gibbs free energy of the binary mixture solution had maximum when temperature is 453.15 K, pressure is 13.374 MPa and CO2 mole fraction in the liquid phase is 0.392. |
