LUBRICITY IMPROVEMENT ADDITIVE FOR GAS TURBINE FUELS
Poor lubricity is an inherent property associated with certain light density and low viscosity fuels – for example naphtha, kerosene and gas condensates. These type fuels provide little or no lubrication to metal surfaces, so that critical components such as gas turbine flow dividers and fuel pumps are likely to experience serious wear and premature failure.
TURBOTECT ER-517N to control corrosion in aggressive naphthas and gas
condensates and TURBOTECT ER-517 are both superior lubricity improvement
additives that have been specially developed to address wear problems in gas
turbine fuel pumps and flow dividers, and to alleviate excessive operational
and maintenance issues when burning low lubricity fuels. The development of
these products represents a break-through in the field of tribology, and
incorporates the most recent chemistry in terms of lubricity improving
Furthermore, unlike earlier-generation products that are available on the
market, TURBOTECT ER-517N and
TURBOTECT ER-517 have been specifically
developed to address the unique technical requirements of the gas turbine
industry. These additives also overcome certain undesirable properties
associated with earlier products, such as solubility, stability and
incompatibility. Turbotect’s careful developmental approach has resulted in
the following product features and benefits:
- Unequalled anti-wear efficiency
- High purity product with ultra-low concentration of trace metal contaminants
- Contains no phosphorous or chlorine compounds
- Excellent mixing and compatibility with a wide range of gas turbine fuels
- Extremely low solids content and high filterability
- No tendency to form troublesome gum deposits
- Absence of any negative interaction with traces of iron present in the fuel
- No interaction with other fuel additives
and TURBOTECT ER-517 are low viscosity lubricity
improvement additives that are effective on a wide range of distillate fuels
such as naphtha, kerosene and gas condensates. The completely oil-soluble
surface-active components go rapidly into solution in the fuel and create a
lubricating film by adsorption onto metal surfaces. Both products are
extremely low in trace metal impurities to ensure compliance with gas
turbine fuel specifications. There are no negative side-effects with other
additives such as corrosion inhibitors or combustion improvers, and no
interaction with fuel impurities such as rust particles, iron, zinc and dirt
etc. The products are extremely stable both in their delivered form and in
solution in the hydrocarbon fuel.
Turbotect lubricity fuel additives are in use:
- In various numbers of gas turbine models like GE Frame 5, GE
Frame 6, GE Frame 9E, GE Frame 9-FA and Mitsubishi.
- On circular and linear types of flow dividers.
- On fuels such as Naphthas, Gas Condensates, Kerosene and various refinery by-product fuels.
Note that the addition of a lubricity improvement additive does not increase the inherent lubricity of the fuel. Wear problems are alleviated by the action of specific surface-active molecules in the additive. These components are adsorbed onto metal surfaces and create an extremely thin lubricating film.
