| Abstract | ||
| The heavy crude oils usually contain considrable amounts of asphaltenes. The high asphaltene contents in the crude oils would decrese the efficiency of the refining processes. Moreever, the high distribution of hetero-atoms (e.g. sulfur and nitrogen) in the asphaltene causes some problems such as pollution, corrosion and catalyst poisining. The main object of this contribution is to investigate the effect of the deasphalting process of crude oils in the sake of improving its properties and consequently increasing the efficiency of the refining processes. Solvent extraction experiments using n-heptane as a solvent were conducted on three types of Egyptian heavy crude oils (Asran, Land Balayim and Geisum), these tests were also performed on three blends from these three crudes with different proportions. The experimental results illustrate that deasphalting process leads to improve some key properties of crudes such as API gravity, viscosity, pour point, total sulfur content, and carbon residue. | ||
