Density and viscosity of orange peel oil saturated with pressurized CO2

Abstract

In this work, we measure the density and viscosity of CO2 saturated orange peel oil liquid mixtures under moderated pressure for the purpose of supercritical process engineering design. A high-pressure falling weight viscometer is used to measure the viscosity of saturated liquid mixtures of orange oil + CO2 at different temperatures (293 K to 333 K) and saturated pressures (2 MPa to 10.3 MPa). An important variation of viscosity (0.35.10−3 Pa.s to 1.10 10−3 Pa.s) is reported in the range of operating conditions. Results show the operating temperature influences the viscosity of both the pure oil and the CO2-saturated oily substrates. The new viscosity data correlates with a simple Arrhenius modified type model.
