What are the advantages compared to mineral oils and in which areas are they used? The Shell Diala S4 range of dielectric oils introduced new technology to the dielectric oil market. Indeed, it is produced from Shell GTL (Gas To Liquid) base oil. Shell GTL (Gas To Liquid) technology makes it possible, from natural gas, to produce base oils of very high purity and a constant chemical structure. Since dielectric oils consist of more than 99% base oil, the quality of the latter directly influences the qualities of the finished product. Compared with conventional mineral oils, they form less sludge and the acidity changes little or not over time, which guarantees less aging of the insulating paper, all of which has a positive impact on maintenance costs. They offer exceptional resistance to degradation in service under the most demanding conditions of use, which makes it possible to reduce untimely shutdowns and the frequency of maintenance operations. Their lifespan is thus longer compared to conventional oils. The Shell Diala S4 range is virtually [1] sulfur free, below the detection limit. It thus responds to the concerns of the transformer and switchgear market relating to copper corrosion due to the development of corrosive sulfur in service. The remarkable viscosimetric properties of GTL oils mean that at low temperatures, these oils retain more favorable flow properties compared to conventional mineral oils: they retain fluidity and help maintain the efficiency of the system. They are used in the fields of production, transmission and distribution of electricity. You indicate that these oils come from GTL technology, what is the process used? Are other products made with GTL technology? GTL technology is produced by a process that uses a modified Fischer-Tropsch reaction to convert natural gas into a series of liquid products. These include cleaner fuels for use in road transport and aviation, and materials used in the manufacture of chemicals and lubricants (naphtha, paraffin and base oil). Shell GTL base oils are derived from natural gas rather than crude oil, which is traditionally used in the manufacturing process. This technology makes it possible to produce base oils of very high purity and of a constant chemical structure. This technology has enabled Shell to develop high-performance oils for various applications: Shell Helix Ultra oils for light vehicle engines, certain products in the Shell Rimula range for heavy-duty diesel engines, but also dielectric oils from the Shell range. Diala S4 for transformers or even turbine oils from the Shell Turbo range. Shell GTL fuels have the potential to improve air quality without requiring any modification to the engines, nor any changes to the existing fuel infrastructure. In which factory are these oils made? Where does the gas used come from? Shell GTL products, including base oils, are produced at the Pearl GTL plant in Qatar, which is the result of a partnership between Shell and Qatar Petroleum. It can produce up to 140,000 barrels per day of GTL products, including 30,000 barrels of base oil per day, or approximately 1 million tonnes per year. Shell then transports these base oils to its lubricant production plants around the world. Pearl GTL was built in Ras Laffan, Qatar in 2010 and is now the world's largest source of GTL products. Pearl GTL is a fully integrated Upstream / Downstream project and is the largest energy project within Qatar's borders as well as Shell's largest single-project equity investment to date. Construction of the plant began in 2006 and the majority of work was completed by the end of 2010. In March 2011, the plant began receiving gas from the North Field in Qatar. Pearl GTL production began in June 2011 and the first commercial delivery was made on June 13, 2011. The plant was extended to reach full capacity at the end of 2012.
