COVER FEATURE Group I Base Oil alternatives for the African Markets Prof. Thomas Norrby D ue to swiping changes in the technology landscape, an appetite for significantly larger volumes of paraffinic base oils of API Group II and Group III is growing, fuelled by ever-increasing demands on automotive engine oil performance. This has led to a massive expansion of Group II and Group III capacity during the last 15 years. These modern base oil production units are more often than not of world-scale capacity, and these products are traded extensively around the world. Group II and Group III base oils are, of course, also increasingly offered to the African market. Mineral base oils differ in production process and properties. Also, the differences in production process lead to differences in production cost and yields. The traditional solvent refining utilized to manufacture “Solvent Neutral” Group I base oils is especially cost sensitive, compared to e.g. modern hydro treatment methods employed in the manufacture of Group II base oils. 18 A combination of production considerations and evolution of market requirements drives the profound changes that are re-shaping the global base oil industry. Economies-of-scale and new capacity investments in Group II and Group III production worldwide has brought a sea change to Europe’s previous role as swing producer and net exporter of Group I base oils. Considerable economic pressure is likely felt by the remaining African base oil refiners. African lubricant blenders, on the other hand, will find themselves competing for evet-scarcer Group I base oils for import into Africa. World-wide, 70% of Group I fluids are utilized for industrial lubricants, 30% for engine oils. In Africa, though, the remaining need for Group I for engine oils will remain high, due to several reasons: many older generation road vehicles in the fleets, challenging logistics and the need for low-cost and
