  • Method for characterizing residual crude oil and petroleum fractions
    Patent number: 6275776
    Abstract: A method to rapidly characterize the hydrocarbon chemistry of heavy residual petroleum mixtures uses three model equations for predicting aromatic carbon content, aromatic hydrogen content and total hydrogen content of the heavy residual oil. The predictive equations are based on three easily measured bulk properties including refractive index, specific gravity and the Watson K factor.
