Results of Infineum Worldwide Winter Diesel Fuel Quality Survey, which measures diesel samples from retail stations in 50 countries and measures them for 33 parameters, including national specifications, exchange specifications, and performance parameters in order to track international trends
- Purpose – to give refining and distribution industry a comprehensive view of the quality of auto diesel fuel in the marketplace, to track international trends
- Method – 335 samples were collected at retail service stations in 50 countries and measured for 33 parameters
- Some of the measurements included: density, kinematic viscosity, Sulphur content, cetane number, cetane index, pour point, distillation, cloud point, CFPP, HFRR, wax content, LTFT, FAME content, rancimat & solid point (full data available for each country)
- Global downward trend in Sulphur levels (only 2 countries had fuels containing more than 1,000 ppm Sulphur)
- Downward trend in global average wear scar diameter (lubricity) has levelled off and remains stable
- Mixed picture for diesel fuel fatty acid methyl ester (FAME) content globally
- First definite signs of hydrogenated vegetable oil (HVO) used as renewable diesel fuel in Europe and U.S.
- Increased demand expected in China and wider Asia Pacific region
- Next 5 years, estimated over 7 million barrels per day of new distillation capacity will be added globally with over 60% coming from Middle East, China & Asia Pacific
- Other parameters tested: cold flow, oxidation
- Looking to the future
- Biggest demand will be in Asia, although Asian countries imposing more stringent legislation (tightening Sulphur limits and increasing use of renewable fuels)
- China V legislation January 2017 (limiting sulfur in diesel to 10ppm) is one example of tightening fuel specifications & will have huge impact on local refineries
- Key is how to maximize production of diesel that meets quality requirements of most lucrative markets while still remaining profitable
- Improving refinery profitability by producing more on specification diesel from every barrel and producing the right fuel for the chosen market is more important than ever
- OEMS expect fuel to delivery vehicle operability, no matter the conditions
