The shape of a viscosity-composition curve, at a fixed temperature and pressure, is widely used to determine whether a homogeneous liquid mixture is ideal or nonideal. This criterion is then used for the prediction of the viscosities of mixtures. The shape of the curve depends strongly upon the component liquids. Ideal mixtures exhibit an approximately linear relationship, whereas non-ideal mixture curves are nonlinear and may exhibit a maximum, minimum, or sometimes both. Thus, the viscosity of a binary liquid mixture can be greater or smaller than that of either of its components. The situation with multicomponent mixtures is even more complex. This first installment of a two-part series discusses experiments conducted on various non-ideal binary mixtures of crude oils, resulting in correlations that predict the viscosities of these types of mixtures.
