- •
Analyses of solid phases from paraffinic oils revealed the presence of asphaltenes.
- •
Asphaltenes with large solubility parameters precipitate together with waxes.
- •
Asphaltenes in deposits show larger solubility parameters than ones in the oil.
- •
Composition of precipitated asphaltenes changes as a function of time.
