Foam formation and mitigation in a three-phase gas–liquid–particulate system

Modification of ilmenite surface chemistry for enhancing surfactants adsorption and bubble attachment

“…Studies on froth flotation have been focused on developing techniques to selectively modify mineral surface chemistry to improve the hydrophobicity and the attachment of particles to air bubbles [8][9][10][11][12][13][14][15], and on investigating the effect of bubble sizes [16,17] and hydrodynamic interaction [18,19], etc. The typical opinion is that the poor ability is due to the reduced particle hydrophobicity and hence less probability of particle/air attachment [20,21].…”

Enhanced oil recovery by nonionic surfactants considering micellization, surface, and foaming properties

“…It is just noted here that the effects on foamability and foam stability of the introduction of nanoparticles are becoming of considerable interest in current research for application in oil fields. The common procedures of foam preparation include shaking (Aronson 1986;Alargova et al 2004;Binks and Tommy 2005;Dickinson et al 2004;Dippenaar et al 1978;Dippenaar 1982a, b;Frye and Berg 1989;Garrett 1979;Garrett et al 2006), bubbling (Frye and Berg 1989;Kulkarni et al 1977;Johansson and Pugh 1992;Pugh 2005;Vijayaraghavan et al 2006), bubbling and shaking (Frye and Berg 1989), bubbling and stirring (Aktas et al 2008;Johansson and Pugh 1992;Schwarz and Grano 2005), and sudden drop in pressure (Dickinson et al 2004;Kostakis et al 2006). It was established that the particle hydrophobicity (Aktas et al 2008;Du et al 2003;Horozov 2008;Hunter et al 2008), size (Aktas et al 2008;Ata 2008;Dippenaar 1982a, b;Frye and Berg 1989;Binks and Tommy 2005), and concentration (Dippenaar 1982a, b;Gonzenbach et al 2006;Zhang et al 2008) affect the foam stability.…”

Peculiarities of the surface crystallization of sodium chloride on mucin films

“…For example, ferrocyanide ions [1,2] inhibit crystallization and affect the morphology of crystals. This property predetermines the wide appli cation of ferrocyanides (K 4 Fe(CN) 6 ⋅ 3H 2 O or Na 4 Fe(CN) 6 ⋅ 10H 2 O) in road services to prevent roads from being covered in ice [3] and in the food industry [4].…”

“…In order to confine the crystallization space of inorganic salts, diverse systems are applied as sub strates: porous stones [1,2,5]; organic and bioorganic templates, including monolayers and LangmuirBlodgett films [7][8][9]; self organized monolayers [10][11][12]; ultrathin organic films [13]; foams [6] and foam films [14]; interfaces between immiscible liquids [15]; and polymer surfaces [13,[16][17][18].…”
