摘要: Asphaltene is the heaviest organic compound in crude oils that its precipitation and deposition cause many negative effects on oil production such as an overall decrease rate increase operating costs. Nanoparticle technology a rapidly growing field may supply alternative novel technique for heavy upgrading recovery. As asphaltene depletion by nanoparticles system close to reality has not been studied yet, this work adsorption process was investigated flow–loop resemble real process. To end, co-precipitation of ferric ferrous ions method applied synthesis maghemite (γ-Fe2O3) nanoparticles. The synthesized (MNPs) were removal from samples system. influence different factors contact time, dose nanoparticles, flow velocity investigated. results mode experiment indicated onto MNPs increases with increasing velocity, MNPs. Kinetic experiments also showed follows nonlinear Thomas model equilibrium could be achieved less than 4 h.
