Description : | Food grade hexane is produced from raw hexane feed by using sulfolane to reduce the unsaturates content. Salient Features of Food grade hexane includes: Use of Sulpholane, 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. |
