Abstract

The applicability of a viscosity-temperature equation, proposed recently for heavy hydrocarbons, is extended to light and medium hydrocarbons. The one-parameter equation was developed for the viscosity of heavy hydrocarbons, including branched/unbranched paraffins/olefins and nonfused/fused aromatic/naphthenic compounds. This generalized equation is demonstrated to be capable of modeling the viscosity of light and medium hydrocarbons that belong to paraffin (alkane), olefin (alkene), (n-alkyl)cyclopentane, (n-alkyl)-cyclohexane, and aromatic families. The results of this study combined with those reported previously yield a generalized one-parameter method for predicting the viscosity of light, medium, and heavy liquid hydrocarbons
