Abstract
Accurate measurements of viscosity coefficients have been made for liquid hydrocarbon mixtures over a wide range of temperature and pressure. At saturation pressure, specially designed viscometers were used to measure the viscosity coefficient of binary, ternary and quaternary n-alkane mixtures, of binary mixtures of five n-alkane plus benzene systems and of benzene plus cyclohexane from 283 K to 393 K, with an estimated accuracy of +/- 0.5 percent. At elevated pressures, a falling-body viscometer with self-centring sinker was used to measure the viscosity coefficient of n-hexane, n-hexadecane and four binary mixtures with an estimated accuracy of +/- 3 percent from 298 K to 373 K at pressures up to 500 MPa or the freezing pressure. To overcome certain weaknesses in design of this instrument, a new viscometer was designed, built and tested. The accuracy of density measurement under elevated pressure was also significantly improved.
