Abstract
A method for the solvent extraction recovery of an aromatic wherein an aromatic extract is formed that contains the aromatic and non-aromatics that are both lighter than and heavier than the aromatic, analyzing at least two separate groups of lighter and heavier non-aromatics in the extract, determining from the analyses the distribution of lighter and heavier non-aromatics present and whether the aromatic product that will be recovered from the process will be too far from its predetermined maximum non-aromatic content specification, and making process changes that will cause the process to produce the aromatic product with a non-aromatic content that is closer to its predetermined maximum non-aromatic content specification.
