New Parameter Derived from the Hansen Solubility Parameter Used to Evaluate the Solubility of Asphaltene in Solvent
[Image: see text] In order to determine whether asphaltenes dissolved in certain solvents, the Hansen solubility parameters (HSPs) of asphaltenes and maltenes extracted from SZ36-1 vacuum residual were measured, and a new parameter Δδ(tn) was obtained by extending the HSP based on the results of asp...

| Sumario: | [Image: see text] In order to determine whether asphaltenes dissolved in certain solvents, the Hansen solubility parameters (HSPs) of asphaltenes and maltenes extracted from SZ36-1 vacuum residual were measured, and a new parameter Δδ(tn) was obtained by extending the HSP based on the results of asphaltene dissolution experiments. Δδ(tn) was calculated by the relative differences of the components of HSP between asphaltene and the solvent. The rationality of the Δδ(tn) was verified from three aspects: the selection of solvent that can dissolve asphaltene, dispersion of asphaltene in various solvents, and compatibility of asphaltenes and maltenes, which further proved that asphaltenes might be dissolved in maltenes. The Δδ(tn) can be well used to judge whether asphaltene can dissolve in a certain solvent. |
