Phase equilibrium and liquid viscosity data for R-290/POE ISO 22 mixtures between 283 and 353 K.

Summary

Novel experimental data and theoretical calculations of bubble point pressure and liquid-phase viscosity for a propane (R-290)/POE ISO 22 binary system are presented. The experimental setup consisted of an oscillating-piston viscometer connected in series with a synthetic variable-volume PVT cell. Experimental data were acquired for R-290 with mole fractions ranging from 0.2 to 0.8, temperatures between 283 and 353 K and pressures up to 22.5 bar. The phase equilibrium (bubble point pressure) was modelled using the Peng and Robinson (1976) and PC-SAFT (Gross and Sadowski, 2001) equations of state, while the liquid mixture viscosity data were predicted with the generalized friction theory (f-theory) of Quiñones-Cisneros and Deiters (2006). The absolute average deviations associated with the phase equilibrium and liquid viscosity calculations were 8.39% and 6.56% (Peng-Robinson and PC-SAFT), and 24.77% (generalized f-theory).
