Rapid Separation of Oil Particles from Low-Concentrated O/W Emulsions in the Presence of Anionic Surfactants Using Fibrous Slag

Mechanistic Heteroaggregation of Gold Nanoparticles in a Wide Range of Solution Chemistry

“…Particle–particle interaction in a singular system, that is, homoaggregation, is primarily influenced by diffusion potential at the colloidal scale and particle collision radius. − Experimental and theoretical studies are well established on the fundamentals of homoaggregation theory and mechanisms for a variation of their surface properties, background solution chemistry, and other physicochemical attributes. ,,− In a more complex natural or biological setting, aggregation occurs in presence of other dissimilar particles – in terms of chemical composition, electrical charge, size, or shape – and is termed as heteroaggregation. − Heteroaggregation of ENMs is identified as an important phenomenon not only in biological and natural systems but also in engineered processes; for example, separation technology, coating processes, food and biotechnological processes, , ceramic industries, and composites or core–shell materials . Nanomaterial interaction in such heterosystems is also likely to be influenced by physicochemical properties and background chemical conditions.…”

An oilfield in Libya: A new model to enhance waste water disposal

“…10 An efficient and cost-effective process for the preparation of waste water for treating and disposal at the Amal oil field has been designed on the basis of existing solutions and studies, 11,12 those applied in other oil fields, [13][14][15][16][17][18] as well as newer equipment and technology. [19][20][21][22][23][24][25] A scheme for the proposed preparation process is provided in Figure 2.…”

Separation of Oil Phase from Dilute Oil/Water Emulsion in Confined Space Apparatus

“…Conventional separation techniques for oil/water emulsion involve gravity settlers [5,6], chemical methods [7][8][9], physical fields (electric field [10,11], acoustical [12], centrifugal [13], etc), air flotation [14,15], porous medium filtration and coalescence (porous beds [16][17][18][19], membranes [20][21][22][23][24]), etc. Gravity settlers are often ineffective for the emulsion with small droplets.…”
