A new strategy of heavy crude oil removal from contaminated soils was studied. The hexane–
acetone solvent mixture was used to investigate the ability of solvent extraction technique for
cleaning up soils under various extraction conditions. The mixtures of hexane and acetone
(25vol%) were demonstrated to be the most effective in removing petroleum hydrocarbons
from contaminated soils and approx 90% of saturates, naphthene aromatics, polar
aromatics, and 60% of nC7-asphaltenes were removed. Kinetic experiments demonstrated …
