Relationship between Asphaltene Adsorption on the Surface of Nanoparticles and Asphaltene Precipitation Inhibition During Real Crude Oil Natural Depletion Tests

Yaser Ahmadi

Volume 10, Issue 3 , July 2021, , Pages 69-82

https://doi.org/10.22050/ijogst.2021.136325

Abstract
  Using nanoparticles for adsorbing asphaltene is an efficient method for upgrading actual oil samples compared to other expensive mechanical treatments or even solvents, such as n-pentane and n-heptane, and surfactants. This study uses nickel–zeolite oxide nanoparticles for asphaltene adsorption ...  Read More

Mohsen Mansouri; Mehdi Parhiz; Behrouz Bayati; Yaser Ahmadi

Volume 10, Issue 2 , April 2021, , Pages 63-89

https://doi.org/10.22050/ijogst.2021.257740.1571

Abstract
  One of the critical issues in the oil industry is related to asphaltene precipitation during different stages, and using nanoparticles is known as a standard method for solving this problem. Although nickel oxide and zeolite have been addressed in previous research to solve the asphaltene precipitation ...  Read More
