ABSTRACT
Liquid vapor (LV) and liquid liquid (LL) phase equilibria in the carbon dioxide + pyrrole system were measured at temperatures between 313K and 333 K, and pressures between 8.4MPa and 15.1MPa. The data were used to predict the overall phase behavior of the system using the Patel Teja equation of state and the Mathias Klotz Prausnitz mixing rules with two temperature-independent parameters. The calculations suggest that the carbon dioxide + pyrrole systemmay exhibit type IV phase behavior according to the classification of Scott and van Konynenburg.
