Solvent deasphalting simulation
Thread Content
It seems that simulating solvent deasphalting based solely on boiling range is clearly insufficient; family composition should also be taken into account.
Asphalt is also a complex mixture; how should one consider its group composition? Should we categorize them roughly? How should the proportions be allocated? Can I find relevant literature?~
The raw materials for solvent deasphalting are mainly vacuum residue, which can be roughly divided into: oil fractions, gums, and asphaltenes； Both gelatinous substances and asphaltenes are polar, while oils are non-polar; like dissolves like, and it is non-polar substances such as propane, butane, pentane, and heptane that enable the separation of vacuum residue into deasphalted oil and asphalt.
At this level, it’s probably impossible to figure it out even when using the software; would it have to be done entirely with virtual components? I haven’t done this simulation before; it seems difficult. . . .
