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)
, Flexible in handling wide boiling range feedstock. Heart cut feed preparation is not required, Low utilities requirement as compared to extractive distillation procesl, Low solvent loss
, Plant adaptations for future needs.
