DOI: 10.1007/978-3-030-16275-7_4
Abstract: Petroleum crude oils are broadly classified as paraffinic, asphaltic and mixed crude oils. Paraffinic crude oils are composed of aliphatic hydrocarbons (paraffins), wax (long-chain normal paraffin) and high-grade oils. Asphaltic crude oils contain large proportions… read more here.
