This model is the key to the development of unprecedented, accurate correlations between the proton spin-lattice relaxation rate, R$\sb1$, and the viscosity, $\eta$, of pure hydrocarbons, with an observed root-mean-square deviations of less than 8.0%. For hydrocarbon mixtures, the notion of "effective" spin-lattice relaxation rate, introduced by Zega et al$\sp{1,2}$, is pursued. Then, simple mixing rules are successfully applied to extend the model to mixtures. The four-parameter corresponding states treatment, utilizing the shape factors as proposed by Leach and Leland$\sp3$, yields correlations of comparable accuracy, when confined to long-chain alkanes. 142 p. application/pdf eng Chemical engineering Corresponding states correlations relating proton spin-lattice relaxation rates of hydrocarbons to viscosities at advanced pressures Thesis Text Chemical and Biomolecular Engineering Engineering Rice University Masters Master of Science Beznik, Frantz.
