Abstract
In ORC, the knowledge of phase diagram of working fluid is essential. In this paper isothermal vapor liquid equilibrium data are presented for the R3310 + R365mfc system. Measurement were performed for seven isotherms (three below and four above the critical temperature of C4F10) ranging from 333.26 to 441.61 K, with pressure ranging from 0.2016 to 3.0927 MPa. The measurements were undertaken using a “static-analytic” type apparatus, with sampling of the equilibrium phases via capillary samples (ROLSI TM ). The maximum uncertainties in the measurements were within ± 0.02 K, 0.0003 MPa and less than ± 0.004 for temperature, pressure, and equilibrium phase mole fractions, respectively. The full set of isothermal vapor-liquid equilibrium data were correlated with the Peng-Robinson equation of state, incorporating the Mathias-Copeman alpha function, with the Wong-Sandler mixing rule utilizing the NRTL activity coefficient model.
