Crude aromatics separation recovers high-purity benzene, toluene, and xylene from feedstocks like reformate or pyrolysis gasoline. The process typically combines liquid-liquid extraction or extractive distillation to separate aromatics from non-aromatics, followed by conventional distillation to fractionate individual products. Solvent-based extraction methods, such as sulfolane or DMSO processes, exploit differences in relative volatility. Downstream distillation trains then separate benzene, toluene, and mixed xylenes with high efficiency. Advanced column internals and heat integration reduce energy consumption while improving product purity. This technology is essential for producing petrochemical building blocks used in plastics, fibers, and solvents.
