| Description |
Solvent separation is frequently applied to petroleum vacuum residues to
reduce the coke-forming tendencies of these materials. This process is capable of
removing all or a substantial amount of asphaltenes from feedstocks that are destined
for further processing and thus applied as the first step of refining. Maltenes and asphaltenes
obtained from vacuum residues of Heera (HVR) and Jodhpur (JVR) Indian
crude oils using n-hexane, n-heptane, and soluble and insoluble fractions obtained
using ethyl acetate, were characterized for elemental analysis, molecular weight, conradson
carbon residue (CCR), specific gravity, and pour points. The resulting degree
of removal of asphaltenes ranged from 10–28 wt% of the HVR and 25–50 wt% of the
JVR. The increasing trend of the American Petroleum Institute (API) gravity and the
decreasing trend of CCR and pour point are observed with the increase in removal of
asphaltenes.
