What the poster is referring to is probably the single-benzene extraction using sulfolane. Many problems have been identified in actual operation; for example, there are issues with the start-up circulation lines for non-aromatic compounds, benzene, mixed hexanes, etc., as well as with the accident handling systems, which can be improved. Additionally, there is high resistance in the vacuum evacuation lines used for vacuum creation
