    • 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.
    • 芳族溶剂萃取回收方法,其中形成芳香族提取物,其含有比芳香族轻和重的芳香族和非芳族化合物,分析了至少两种分开的较轻和较重的非芳族化合物 提取,从分析中确定更轻和更重的非芳族化合物的分布,以及将从该方法中回收的芳族产物是否将远离其预定的最大非芳族含量规格,并且使得过程变化将导致 制备具有更接近其预定的最大非芳族含量规格的非芳族含量的芳香族产物的方法。
