Wax melting temperature

Bridie et al. (1) found that asphaltenes are two to five times more effective than waxes as stabilizing agents. In a stable emulsion containing 6.6% asphaltenes and 9.8% wax, the emulsion was still stable if 90% of asphaltenes were removed. Waxes as crude oil stabilizers for North Sea crudes have been investigated by Thompson et al. (133, 134) who showed that waxes melt as the temperature increases, and separation efficiency increases at 60°C, which is above the wax melt temperature.
