Abstract
An improved process for the extraction of aromatics from a mixed feed provides additional flexibility of operation which is especially useful when the feed contains relatively large amounts of nonaromatics and therefore produces a large raffinate stream. Water for washing the non-aromatic raffinate is obtained in part by condensing a portion of the steam generated for stripping aromatics from the extract.
