“…Asphaltenes, resins Asphaltenes clusters [31] In their work, they noticed the existence of a critical concentration of asphaltene (around 10% in toluene) that corresponded to a significant change in the foamability, foam-film lifetime, surface tension and viscoelasticity. These effects were attributed to the formation of asphaltenes clusters.…”

“…Adil and Maini [30] suggest that the presence of asphaltenes facilitates the bubble nucleation and protects bubbles from coalescence. Bauget et al [31] have tested toluene solutions with different amounts of asphaltenes and resins to systematically investigate the effect these compounds have on foam lifetime. Callaghan et al…”

“…Stevenson [3] addressed how particles stabilize foam by using maximum capillary pressure arguments to explain the stabilization and observed dependence on particle size. Related to the increased stability by small particles, in the crude oil industry, insoluble nanoaggregates of asphaltenes have been found to influence crude-oil foam stability [31].…”

D o s s i e rRe´sume´-Mousses non aqueuses et mousses pe´trolie`res -Les mousses produites a`partir de syste`mes non aqueux sont moins fre´quentes que les mousses a`base d'eau, mais elles jouent un roˆle important dans de nombreuses applications et proce´de´s industriels. La faible tension de surface des liquides a`base d'hydrocarbures limite l'adsorption des agents de surface classiques et par conse´quent diffe´rents compose´s et me´thodes doivent eˆtre conside´re´s afin de ge´ne´rer et de stabiliser les mousses a`base d'huile. De meˆme, le cassage des mousses non aqueuses inde´sirables ne´cessite des conside´rations spe´cifiques a`ces syste`mes. Les mousses de pe´trole pre´sentent un inte´reˆt particulier de par leur complexite´en raison de la grande varie´te´des compose´s et des gaz qui peuvent les constituer. Nous pre´sentons dans cet article un aperc¸u des principaux me´canismes reconnus comme importants pour la stabilite´des mousses non aqueuses avec une conside´ration toute particulie`re pour les mousses de pe´trole brut.Abstract -Non-Aqueous and Crude Oil Foams -Foams produced from non-aqueous media are less common than water-based foams but they play an important role in many industries and engineering processes. The low surface tension of hydrocarbon fluids limits the adsorption of common surface activity substances and different compounds and methods must be considered to generate and stabilize oil-based foam. Likewise, the destruction of unwanted non-aqueous based foam requires specific considerations not found with aqueous systems. Of particular interest are petroleum-based foams, which are highly complex due to the wide variety of compounds and gases that can be found. We provide an overview of the major mechanisms known to be important for non-aqueous foam stability with a spotlight on crude-oil foams.
