Analytical Study of Affecting Gasoline Quality Properties on Environment and Its Conformity with Specifications

Abstract

Gasoline is an important fuel in human life, but it is also responsible fordeteriorating Ambient Air Quality (AAQ) through fugitive and exhaustemissions. In this study, chemical properties (Sulfur and Lead content) ofgasoline production at Al-Daura refinery were verify based on a statisticalquality control tool. Gasoline samples were examined in January/2011and compared with samples examined in January/2019. In this study, itwas concluded that the average production process and process variabilityfor Sulfur content and added Lead value are stable. In January/2011Sulfur content conforms to Iraqi and European standard specifications,but Lead value doesn’t conform to Iraqi standards, where internationallythe use of lead to enhance engine performance has been banned since the1970s of a century ago because it’s large dangerous on the environment.In January/2019 Sulfur content conforms to Iraqi standards but doesn’tconform to European standards specifications. The addition of lead togasoline is stopped in 2016; imported gasoline was used by blend it withproduced gasoline at al Daura refinery to raise its quality. Gasolinequality properties must be improved and tighten up according tointernational standards to save our environment
