Abstract
Processes for the recovery of aromatic hydrocarbons from one or more vent gas streams associated with an aromatic complex. The vapor streams are passed to an absorption zone in which an aromatic-selective solvent absorbs the aromatics. The aromatic-selective solvent can be processed along with other solvent extraction streams within the aromatic complex. The absorption zone may be a portion of an existing vessel or column, such as an extractive distillation column or a stabilizer.
