Emulsions surface chemical aspects

From the discussion above, it is clear that, from a surface chemical point of view, one aspect of emulsion stability is of primary importance—the protection of the emulsion droplets from coalescence. As a result, that area has received the greatest... [Pg.288]

Several alkaline chemicals have been employed for various aspects of enhanced oil recovery. Two of the most favorable alkaline chemicals tested and used in tertiary oil recovery are sodium orthosilicate and sodium hydroxide. Comparing their characteristics, both chemicals react with acids in crude oil to form surfactants, precipitate hardness ions and change rock surface wettability. One difference between the two chemicals is that the interfacial properties for sodium orthosilicate systems are less affected by hardness ions (13), hence slightly lower interfacial tensions would occur. Lower Interfacial tensions can aid in in-situ emulsion formation. [Pg.217]
