Abstract:A unique approach is proposed to predict the heavy oil density using a recently developed three parameter cubic equation of state for heavy pure components. It predicts the heavy oil density with an AAD of 2.5%. The new model does not require any experimental density data for its tuning. The basic assumption in this work is that heavy oil is a mixture of n-alkanes and aromatics as the most prominent groups. Critical pressure characterisation for pseudo fractions is done by tuning a perturbation factor (f c ), … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
