A feed stream (12) of asphaltene-containing residual oil is processed by contacting the feed stream with a solvent (13) to form a first primary liquid stream (14) containing deasphalted oil and some solvent, and a second primary liquid stream (15) containing asphaltene and some solvent. The first and second liquid streams (14 and 15) are heated; and the heated streams (14 and 15) are respectively processed to recover the solvent and to produce a deasphalted oil product stream (16) substantially free of solvent, and an asphaltene product stream (18) substantially free of solvent. A portion (40) of the DAO product stream (16) is heated (41) to produce a stream (42) of heated deasphalted oil, a portion (43) of which indirectly heats the two primary liquid streams (14 and 15).
Flux d'alimentation (12) en huile résiduelle chargée d'asphaltènes traité par contact avec un solvant (13), pour constituer un premier flux liquide primaire (14) à base d'huile désasphaltée et d'une certain quantité de solvant et un second flux liquide primaire (15) à base d'asphaltène et d'une certaine quantité de solvant. On chauffe les deux flux liquides (14 et 15) en question, puis on les traite respectivement pour récupérer le solvant et fournir un flux de produit à base d'huile désasphaltée (16), sensiblement sans solvant, et un flux de produit à base d'asphaltène (18), sensiblement sans solvant. On chauffe (41) une partie (40) du flux de produit à base d'huile désasphaltée (16), afin de constituer un flux (42) d'huile désasphaltée chauffée, dont une partie (43) chauffe indirectement les deux flux liquides primaires (14 et 15).
