Abstract
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.
Highlights
The quality of motor gasoline is specified by measuring its various Physico-chemical properties measured by about 20 various properties
The research problem is that most petroleum refineries facing the challenges of producing gasoline that has all of the qualifying properties as well as responding to increased environmental regulations and health restrictions on vehicle emissions
The gasoline produced in the Daura refinery in one grade with octane number 81 through the period January/2011 to January/2019
Summary
The quality of motor gasoline is specified by measuring its various Physico-chemical properties measured by about 20 various properties. The sulfur and lead content of gasoline produced in the Daura refinery are manipulated to assess the effect of fuel composition on air pollutant emissions and conformity to Iraqi and European standards based on quality control tools. Vehicle emission standards from the European Union (EU) are active and require further reduction in carbon exhaust emissions from carbon monoxide (53%), hydrocarbons (67%), and nitrogen oxides (68%) relative to the Euro I standard which became in 1992. This requires adapters (catalytic) on all cars too.
