Improved process for deasphalting residua by reactive recycle of high boiling material

The vaporized fraction is passed via line (11) to soaker drum (2) which is maintained at effective conditions so that the highest boiling materials are condensed out. Typically these conditions will include controlled quenching of vapor fraction just below the dewpoint. A quench stream can also be p...

Beschreibung
Zusammenfassung:	The vaporized fraction is passed via line (11) to soaker drum (2) which is maintained at effective conditions so that the highest boiling materials are condensed out. Typically these conditions will include controlled quenching of vapor fraction just below the dewpoint. A quench stream can also be passed into soaker drum via line (21).
