Abstract:
Asphaltene Adsorption onto surface nanoparticles is an attractive subject for the oil industry because nanoparticleswould remove asphaltenes from the crude oil rapidly and thus make the remaining fraction of crude oil transportablefor conventional processing. In this work, the adsorption of asphaltenes from crude oil model solutions ontocolloidal nanoparticles of SiO2 nanoparticles were investigated. Asphaltene Adsorption isotherms were obtained andthe resultant shows isotherm is in good Compromise with the Langmuir isotherm model. Bottle test uses forevaluation demulsification of crude oil. Also, the result of demulsification of SiO2 indicates this nanoparticle betterthan industrial demulsifier for dehydration of crude oil in all concentration.
