Abstract: As the core of the whole unit, the extraction distillation tower of the aromatics extraction unit has a direct influence on the quality of raffinate and benzene. Du
e to the particularity of liquid-liquid extraction and the easy degradation of sulfolane solvent, the production operation is great difficult. In this paper, the quality fluctuation of the raffinate oil product caused by the abnormal fluctuation of the distillation tower was analyzed, and relatively feasible solutions were put forward.
