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.
