Zusammenfassung: | New simultaneous process for deasphalting and desalting heavy hydrocarbon oils applicable particularly to very dense and very viscous crude oils, consisting in forming an emulsion of oil 1 in water 2 in which the continuous phase is water and in bringing this emulsion 4 into contact with a sufficient quantity of deasphalting solvent 5 to form two separate phases which are separated 9 and 10. The upper phase 9 consists of a mixture of deasphalted and desalted oil and of deasphalting solvent. The lower phase 10 consists essentially of a suspension of asphalts in water, which can be easily pumped.
NOUVEAU PROCEDE SIMULTANE DE DESASPHALTAGE ET DE DESSALAGE D'HUILES LOURDES D'HYDROCARBURES S'APPLIQUANT PARTICULIEREMENT AUX HUILES BRUTES TRES DENSES ET TRES VISQUEUSES, CONSISTANT A FORMER UNE EMULSION HUILE 1 DANS EAU 2 DONT LA PHASE CONTINUE EST L'EAU, A METTRE CETTE EMULSION 4 EN PRESENCE D'UNE QUANTITE SUFFISANTE DE SOLVANT DE DESASPHALTAGE 5 POUR FORMER DEUX PHASES DISTINCTES QUI SONT SEPAREES 9 ET 10.LA PHASE SUPERIEURE 9 EST CONSTITUEE PAR UN MELANGE D'HUILE DESASPHALTEE ET DESSALEE ET DE SOLVANT DE DESASPHALTAGE.LA PHASE INFERIEURE 10 EST CONSTITUEE ESSENTIELLEMENT PAR UNE SUSPENSION D'ASPHALTES DANS L'EAU, FACILEMENT POMPABLE. |
