Aromatic Extraction technology for production of Benzene & Toluene, using sulfolane as solvent
Description
This technology is used for production of benzene, toluene, xylene from aromatic rich feedstocks such as catalytic reformate and hydrogenated pyrolysis gasoline:
-
Production of special boiling point solvents.
Production of low aromatic feedstocks for fertilizer and petrochemical plants.
Salient Features
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 process.
Low solvent loss
Plant adaptations for future needs.
Commercialization:
This technology was developed by CSIR- IIP in 1978 in collaboration with EIL. First adopted in 1985 at BPCL Mumbai
