摘要: Abstract Solid-stabilized water-in-oil emulsions are commonly encountered in the production of crude oil and synthetic fuel liquids. The ability finely divided solids to stabilize these is due adsorption asphaltenes other heavy ends from on mineral surface which imparts solid its hydrophobic nature. This study presents results quantify particle—fluid interactions by means measurements sodium montmorillonite particles. influence asphaltene contact angle at water/oil/solid interface zeta potential particles was investigated. nature found be directly related amount adsorbed their surface. effect explained terms interfacial tensions oil/water solid/water interfaces. pH surfactant concentration aqueous phase assessed.
