Introduction
Poor lubricity is an inherent property associated
with certain light density and low viscosity fuels
– for example naphtha, kerosene and gas
condensates. These type of 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
The Solution
Addition of efficient lubricity improvement
additives in Naphtha helps to avoid wear &
tear problems in gas turbine fuel pumps and
flow dividers. Servo NLI has been specifically
developed to address the unique technical
requirements of the gas turbine industry. The
addition of this product in naphtha will result
in the following benefits:
Excellent anti-wear efficiency.
Ultra-low concentration of trace metal
contaminants.
Contains no phosphorous or chlorine
compounds.
Excellent miscibility and compatibility with
a wide range of gas turbine fuels
Very low un-filterable contaminants and high
filterability rate.
Stable additive with no tendency to form gum
deposits.
