Crude Oil Interfacial Tension Reduction and Reservoir Wettability Alteration with Graphite or Activated Carbon/Silica Nanohybrid Pickering Emulsions
In this research, two carbon structures silica nanohybrids Pickering emulsions were prepared. Graphite and activated carbon were carbon allotropes with different morphologies of laminar and spherical, respectively. The effect of carbon morphology investigated on the related silica nanohybrids Pickeringemulsions for C-EOR. Therefore, nanohybrids were prepared with graphite and activated carbon t...
متن کاملEffective Factors on the Stability of Oil-in-Water Emulsion Based Beverage: A Review
Beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. They must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. Two immiscible phases contained systems are thermodynamically unsta-ble. In other words, they are vulnerable to bre...
متن کاملFormation and Stability of Emulsions: Effect of Surfactant-particle Interactions and Particle Shape
Formation and stability of emulsions is one of the important topics in the field of colloids and interfacial science. Surfactants and colloidal particles are often used to stabilize emulsions. Surfactants are amphiphilic molecules; they minimize the energy required for the emulsion formation by reducing oil-water interfacial tension. Colloidal particles are not amphiphilic, but partially wettab...
متن کاملEffect of Salinity, pH, and Temperature on Stability of Gas Condensate in Water Emulsions Using Different Surfactants
Light hydrocarbons in water emulsions are formed in many gas refinery wastewaters, and its stability depends on some parameters such as temperature, pH and salinity. In this study, different surfactants have been used to prepare gas condensates in water emulsion along with four surfactant kinds namely, Span 80, Tween 80, CTAB, SDS and Span 80 and Tween 80 mixture. For this purpose,...
متن کاملPhysicochemical and Emulsifying Properties of Barijeh (Ferula gumosa) Gum
Ferula gumosa Boiss is one of the natural plants of Iran whose exudates (Barijeh) can be used in food industry. In the present study the properties of the gum extracted from tubers of Ferula gumosa were examined. For this purpose, gum was extracted from crude exudates by alcoholic extraction with 90% (v/v) ethanol. The purity of gum was relatively high, and it was composed mostly ...
