The bubble point and dew point curves which define the liquid-vapor and solid-vapor domains for separation are obtained by generating the pressure-temperature phase diagram. The simulations are performed using Aspen HYSYS. The validation for the use of PR model is done by comparing the results of CO 2 freeze-out temperature predictions for PR and Soave-Redlich-Kwong (SRK) model with the experimental data available in the literature. © Published under licence by IOP Publishing Ltd. publisher: Institute of Physics Publishing date: 2018 type: Conference or Workshop Item type: PeerReviewed identifier: Qasim, A. and Shariff, A.M. and Sufian, S. and Ayoub, M. and Lal, B.
