Abstract: Recently, a novel approach to the characterization of petroleum mixtures based on substitute mixtures of real components has been described. This approach can replace the traditional approach based on pseudo-components. It can be shown that the approach based on real components is also well-suited for certain special tasks in the modelling of oil processing. Very often it is needed to blend petroleum fractions. It is shown how to modify the basic algorithm for assembling the substitute mixture of real components in order to cover also this problem. Second interesting area is incorporation of compounds containing sulphur, which is currently in the focus of refiners according to increasing environmental demands. The content of thiols and other compounds having impact on the environment is rather low but cannot be neglected for the simulation of separation processes if the results should be realistic and showing the way how to decrease the content of sulphur in gasoline mixtures. The adoption of the algorithm for the selection of real components into the substitute mixture for both cases is described and documented by examples.
