Foaming of organic liquids: from advancement in theorical understanding to practical applications

Résumé

Foaming of non-aqueous liquids, particularly in the energy sector, presents significant challenges due to the transient stability of these systems. Despite being free of surfactants, non-aqueous liquids are observed to foam in practice. This phenomenon is observed during the simultaneous production of gas and liquids, affecting transportation and separation processes. The stability of foams can impact pressure drops, production efficiency, and safety. The study of foam stability in organic liquids has focused on understanding the factors that enhance stability within liquid films. Solid or solid-like particles within the liquid film, such as fat crystals or asphaltenes, can stabilize oil foams. Recent advancement on particle-free liquids have also shown that blends of organic liquids, even when totally miscible, can produce surfactant like effects stabilizing foams. Experimental methods, including depressurization tests and surface tension measurements, were employed to study the foaming behavior of various crude oils, and the results were compared with the learnings from the literature.
