Sulfur

Gasoline fuel contains sulfur, which is derived from the original crude oil source and can still be present after refining. After combustion in the engine, the sulfur in fuel forms particulates that are primary contributors to air pollution and the cause of harmful corrosion in the engine.

Turkmenistan produces mainly gasoline grades RON 80, RON 92 and RON 95. The country’s fuel production fully meets local demand; it exports all three gasoline grades to neighboring countries. SGS INSPIRE will give an overview of the sulfur content per gasoline grade.

The figure below indicates that in 2011 and in 2014 the sulfur content in locally produced gasoline grades RON 92 and RON 95 (regular and premium) ranged from 120 to 370 mg/kg, which is less than the maximum limit of 500 mg/kg. A samplin
