Preparation of Hydrophobic Monolithic Supermacroporous Cryogel Particles for the Separation of Stabilized Oil-in-Water Emulsion
نویسندگان
چکیده
Here, we prepared hydrophobic cryogel particles with monolithic supermacropores based on poly-trimethylolpropane trimethacrylate (pTrim) by combining the inverse Leidenfrost effect and cryo-polymerization technique. The adopting this method demonstrated separation of stabilized O/W emulsion surfactant. were characterized in terms macroscopic shape porous structure. It was found that had a narrow size distribution supermacroporous hydrophobicity confirmed placing aqueous organic droplets particles. Where droplet immediately adsorbed into particles, remained surface particle due to repelling force. In addition, after it observed, solvent diffused entire particle. indicated pores distributed from interior. Regarding application oil-in-water emulsion, resulting successful removal emulsion.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Enhanced Acoustic Separation of Oil-Water Emulsion in Resonant Cavities
This paper explores the use of acoustics for the recovery of oil in oil-water emulsions. A series of experimental studies were conducted using acoustic standing waves in resonant cavities as means of trapping oil droplets and enhancing oil separation. Several cavity configurations were explored and the frequency range used was between 1 MHz-2 MHz. Oil-water emulsions studied were made using min...
