Liquid viscosities of the ternary system benzene + cyclohexane + n-tetradecane from (313 to 393) K and pressures up to 60 MPa

Liquid viscosities of eight mixtures for the ternary system benzene + cyclohexane + n-tetradecane were experimentally measured using a rolling-ball viscometer from (313.2 to 393.2) K and at pressures up to 60 MPa. We performed the modeling of the measured mixture viscosity data (256 points) by applying the Grunberg - Nissan (GN) and Katti - Chaudhri (KC) correlations and a liquid viscosity model based on Eyring's theory coupled to a cubic equation of state (ET-EoS) by using a single temperature-independent binary interaction parameter for the benzene + n-tetradecane, benzene + cyclohexane, and cyclohexane + n-tetradecane systems. Results of the modeling process yielded an average absolute deviation of (4.9, 5.3, and 6.7) % for the GN, KC, and ET-EoS viscosity models, respectively, which show that the GN model is superior to the KC and ET-EoS models in predicting the whole viscosity - temperature - pressure - composition surface of the ternary system studied.
