الملخص الإنجليزي

Gasoline is a mixture of multiple components, gasoline quality plays leading role in most refineries; because it determines (60- 70) % of refineries profit.

In this study factors affecting gasoline quality were verified, major gasoline quality parameters are identified and assessed to study the impact of gasoline quality on the engine performance, processing and environment.

640 samples of different Iraqi gasoline blends produced at al- Daura refinery are collected over (21) consecutive months (April 2010- December 2011) to perform this study.

Four major quality parameters were investigated in this research according to Iraqi standard (2000) they are; Research Octane Number (RON), Reid Vapor Pressure (RVP), Sulphur content, and lead content.

Statistical quality control tools are used to perform this assessment.

Results revealed that change average of Process of RON and RVP parameters during monthly evaluation and from month to month evaluation is low and they have the largest impact on engine performance compared with other gasoline studied parameters, it was found that RON has 38.5% impact on engine performance while RVP has 30.8%.

On the other hand sulphur has the largest impact on environment it was 37.5%.

Also results show an improvement towards less value lead, sulphur contents, and a rise in RON value starting with (July/ 2011) from (81 RON) reached to (87 RON).

These improvements in gasoline quality parameters continued up to the end of 2011.

Gasoline production processes are monitored and evaluated; however during the study period gasoline production process was rather stable (there aren’t samples out of control limits) but still doesn’t conform to Iraqi standards until (July / 2011).

Thus there is a gap between gasoline quality standards specifications compared with international standards.

A model of Quality Feedback System for Petroleum Products (QFSPP) is implemented to integrate and interlink gasoline production process activities with quality control and maintenance department and to enhance quality feedback system.

This may change the control system at Al-Daura refinery to closed system, so as to improve and tighten up gasoline quality parameters and to keep pace with the international standards.
