Food Grade Hexane 

Food grade hexane production process from raw hexane feed using sulpolane/NMP as a solvent.

Food grade hexane production process can be widely used in petrochemical industry.

• Use of Sulpholane/NMP, as extraction solvent, possesses a favorable combination of solvent power and selectivity
• Globally hydrogenation route is preferred for removal of benzene and olefins from naphtha fractions.
• Hydrogenation route is unattractive for feeds with high aromatic content, as it requires higher capital investment
• Sulpholane extraction technology developed at IIP can accept feed with any benzene content and is economical as compared with hydrogenation
