| Popis: | Crude oils are mostly produced as W/O emulsions. These have to be demulsified. They are stable against coalescence but not against flocculation. They are stabilized by the enrichment with film formation on the interface of asphaltenes and petroleum resins. The coalescence of water droplets in a continuous oil volume phase were investigated and interpreted with the pressure of the curvature. |
