This technology is used in petroleum industry for production of benzene, toluene, xylene from aromatic rich feedstocks such as catalytic reformate and hydrogenated pyrolysis gasoline. Use of Sulpholane, as extraction solvent, possesses a favourable combination of solvent power and selectivity resulting in the production of aromatic hydrocarbons in high purity (99.9% +) and yields( Aliphatic impurities < 300 ppm).This technology is flexible in handling wide boiling range feedstock. Heart cut feed preparation is not required. Low utilities requirement as compared to extractive distillation process.
