Process and apparatus for solvent-deasphalting residual oil containing asphaltenes |
摘要 |
A feed stream of asphaltene-containing residual oil is processed by contacting the feed stream with a solvent to form a first primary liquid stream containing deasphalted oil (DAO) and some solvent, and a second primary liquid stream containing asphaltene and some solvent. The first and second liquid streams are heated; and the heated streams are respectively processed to recover the solvent and to produce a DAO product stream substantially free of solvent, and an asphaltene product stream substantially free of solvent. A portion of the DAO product stream is heated to produce a stream of heated DAO, a portion of which indirectly heats the two primary liquid streams. |
