Classification and Characterization - SpringerLink
Sep 8, 2024 · Petroleum crude oils are broadly classified as paraffinic, naphthenic/asphaltic, and mixed. Paraffinic crude oils are composed largely of aliphatic hydrocarbons (paraffins), wax (long-chain normal paraffin), and high-grade oils. They also contain lesser amounts of naphthenic and asphaltic (bituminous) material.
