Mobil SHC 800 Series turbine oils are designed specifically to meet the needs of the most severe industrial gas turbine applications with a nominal 10,000 hour TOST life.
Mobil SHC 800 Series turbine oils are designed specifically to meet the needs of the most severe industrial gas turbine applications with a nominal 10,000 hour TOST life. They are recommended for the lubrication of land-based gas turbines, particularly units under 3,000 hp used as standby power units, and in some types of total energy and combined cycle (gas/steam) systems. This innovative product family is formulated from wax-free synthesized hydrocarbons and a unique additive system. This formula provides outstanding low temperature fluiditiy and exceptional resistance to degradation at high temperatures well beyond the capabilities of premium quality mineral oils. Mobil SHC 800 Series lubricants also provide excellent antiwear properties as well as protection against rust and corrosion plus good air release performance and resistance to foaming.
These characteristics provide superior resistance to thermal/oxidative degradation during the heat soaking period after shutdown and permit rapid oil circulation at low temperatures during start-up. Degradation resistance is a key attribute in avoiding harmful deposits that can interfere with lubrication supply to the bearings or foul critical servo-valves. This is a particular issue when gas turbines are running in cycling mode and experience multiple thermal stress cycles. Since low temperature fluidity and high viscosity index are inherent characteristics of the fluids, they do not change in service as a result of mechanical shearing or repeated cycling from low to high temperatures. Mobil SHC 800 Series oils are fully compatible with mineral oils, but admixture will detract from its superior performance properties
These progressive products, which have been proven in very severe gas turbine service over many years, are preferred by users because of their outstanding stability and equipment protection under the most severe, high temperature conditions, and because of their easy start-up at low ambient temperature. This performance results in excellent equipment reliability and minimized downtime.
Features & Benefits
The Mobil SHC brand of lubricants are recognised and appreciated around the world for their innovation and outstanding performance. These molecular design synthetic products, pioneered by our research scientists, symbolise the continuing commitment to using advanced technology to provide outstanding products. Mobil brand products have also been the choice for turbine operators worldwide since they were first commercialized more than one hundred years ago. During that period our technical experts have stayed in close contact with OEMs to ensure that our product offerings would provide exceptional performance in the continually evolving turbine equipment designs. Familarity with evolving designs and operational conditions is a key input to the application of the best lubricant technology in the development of products that will provide the performance demanded by users.
One general trend over the years has been to higher power output designs, which can lead to greater thermal stress of the lubricant. This thermal exposure is exacerbated by cycling operation which is employed by gas turbine operators to manage the supply/demand balance of electrical power generation, which results in heat soak-back at each shut-down sequence. Resisting thermal degradation is thus a key property required of a modern gas turbine oil lubricant.
To combat high thermal exposure of the oil, our product formulation scientists chose proprietary synthetic base oils for Mobil SHC 800 Series oils because of their exceptional thermal/oxidative resistance capabilities. Our formulators chose specific additives that would maximize the benefits of the synthetic base oils to provide exceptional oil life and deposit control and resistance to thermal & chemical degradation, as well as the balance of the performance features. The wax-free nature of the synthetic base oil also provides low temperature fluidity characteristcs unmatched by mineral products and is a key benefit for remote, low ambient applications.
Mobil DTE 790 Series lubricants are premium performance turbine oils that are engineered to meet the requirements of the most severe steam turbine designs and operation, with maximum oil charge life.
Mobil DTE 790 Series lubricants are premium performance turbine oils that are engineered to meet the requirements of the most severe steam turbine designs and operation, with maximum oil charge life. Mobil DTE 790 Series oils are based on proprietary, very high quality, hydrotreated base stocks and selected additives which provide outstanding resistance to oxidation and chemical degradation over time, which is exemplified by exceptional color stability, a key factor in assessing oil stability in some regions of the world. Mobil DTE 790 lubricants also exhibit excellent water separability, resistance to emulsion formation and anti-foaming characteristics which provides efficient operation, and good air release properties which is critical for hydraulic control mechanisms.
The exceptional oxidation stability performance of Mobil DTE 790 oils has resulted in outstanding performance in even the most severe, and largest capacity steam turbine applications. These products have an outstanding reputation for equipment reliability and avoiding unscheduled downtime. This reputation is exemplified by the very high percent of nuclear turbine operators who choose Mobil DTE 790 lubricants. Their performance in service is also recognized to provide very long charge life, in excess of conventional turbine oils, and high resistance to deposit formation and filter plugging. While primarily engineered for steam turbine service, Mobil DTE 790 Series oils also find application in non-geared gas turbine service.
The performance features of Mobil DTE 790 Series oils translate into excellent equipment protection, reliable operation, with reduced downtime and extended oil charge life. Mobil DTE 790 Series oils, in the appropriate grade, meet or exceed the requirements of major steam and gas turbine builders.
