Supercritical Fluid Impregnation of Broken Stone with Deasphaltizate Obtained from Oil Residue

详细

Results are presented concerning the studies on obtaining a heavy oil residue, its deasphalting and the impregnation of crushed carbonate stone with deasphaltizate. The heavy oil residue is obtained via the separation of extra-heavy crude oil using a steam thermal method. The deasphalting of the oil residue and the impregnation of crushed carbonate stone are carried out using a propane-butane solvent in the liquid and supercritical fluid state, respectively.
