Analytical study of affecting gasoline quality properties on environment and its conformity with specifications

Abstract EN

Gasoline is an important fuel in human life, but it is also responsible for deteriorating Ambient Air Quality (AAQ) through fugitive and exhaust emissions.

In this study, chemical properties (Sulfur and Lead content) of gasoline production at Al-Daura refinery were verify based on a statistical quality control tool.

Gasoline samples were examined in January / 2011 and compared with samples examined in January / 2019.

In this study, it was concluded that the average production process and process variability for Sulfur content and added Lead value are stable.

In January / 2011 Sulfur content conforms to Iraqi and European standard specifications, but Lead value doesn’t conform to Iraqi standards, where internationally the use of lead to enhance engine performance has been banned since the 1970s of a century ago because it’s large dangerous on the environment.

In January/2019 Sulfur content conforms to Iraqi standards but doesn’t conform to European standards specifications.

The addition of lead to gasoline is stopped in 2016; imported gasoline was used by blend it with produced gasoline at al Daura refinery to raise its quality.

Gasoline quality properties must be improved and tighten up according to international standards to save our environment.
