摘要： A hydrocarbon source feed is upgraded using a solvent deasphalting (SDA) unit employing a solvent having a critical temperature Tc by initially separating from a first hydrocarbon input stream fractions with an atmospheric equivalent boiling temperature less than about Tf° F. for producing a stream of Tf−fractions and a residue stream (Tf+ stream), where Tf is greater than about Tc−50° F. In the SDA unit, a second hydrocarbon input stream which includes the residue stream is deasphalted for producing a first product stream of substantially solvent-free asphaltenes, and a second product stream containing substantially solvent-free deasphalted oil (DAO). The source feed may be included in either the first or second input streams. The DAO in the second product stream is thermally cracked for producing an output stream that includes thermally cracked fractions and by-product asphaltenes produced by thermally cracking the DAO. Finally, at least some the said thermally cracked fractions are included in the first input stream.

摘要： A hydrocarbon source feed is upgraded using a solvent deasphalting (SDA) unit employing a solvent having a critical temperature T.sub.c by initially separating from a first hydrocarbon input stream fractions with an atmospheric equivalent boiling temperature less than about T.sub.f .degree. F. for producing a stream of T.sub.f.sup.- fractions and a residue stream (T.sub.f.sup.+ stream), where T.sub.f is greater than about T.sub.c -50.degree. F. In the SDA unit, a second hydrocarbon input stream which includes the residue stream is deasphalted for producing a first product stream of substantially solvent-free asphaltenes, and a second product stream containing substantially solvent-free deasphalted oil (DAO). The source feed may be included in either the first or second input streams. The DAO in the second product stream is thermally cracked for producing an output stream that includes thermally cracked fractions and by-product asphaltenes produced by thermally cracking the DAO. Finally, at least some the said thermally cracked fractions are included in the first input stream.

摘要： Upgrading of a hydrocarbon feed containing sulfur, metals, and asphaltenes involves applying the feed to a distillation column for producing a substantially asphaltene-free, and metal-free fraction and a non-distilled fraction containing sulfur, asphaltenes, and metals. At least some of the substantially asphaltene-free, and metal-free distillate fraction is converted to a hydrogen donor diluent. The non-distilled fraction is processed in a solvent deasphalting unit for producing a deasphalted oil stream and an asphaltene stream. After a combined stream is formed from the hydrogen donor diluent and the deasphalted oil stream, the combined stream is thermally cracked forming a thermally cracked stream that is applied to the distillation column. Also, an apparatus for upgrading a hydrocarbon feed containing sulfur, metals, and asphaltenes, the apparatus comprising: a distillation column for receiving the feed and producing a substantially asphaltene-free, and metal-free distillate fraction and a non-distilled fraction containing sulfur, asphaltene and metals; and means for producing a hydrogen donor diluent from at least some of the substantially asphaltene-free, and metal-free distillate fraction. The apparatus also includes a solvent deasphalting unit for processing the non-distilled fraction and producing a deasphalted oil stream and an asphaltene stream and combining the hydrogen donor diluent with the deasphalted oil stream to form a combined stream; and a thermal cracker for thermally cracking the combined stream and forming a thermally cracked stream whereby the thermally cracked stream is applied to the distillation column.
