SUMMARY
The research discusses some modern concepts in the sector of operations management represented in green design, the cleanest process and the green product. Enhancing the process could lead to enhancing the product and then achieving better environmental performance. Therefore, the research deals with addressing the problem of water pollution because of the production process as a result of the environmental effect resulting from the production of fuel in the Dora refinery. The research aims at showing the effect of applying the technique of (alkylation) in the production of (cars fuel) to reduce waste and to clarify the effect of the alternative situation in the treatment of the process. The research importance stems from the application of tools and appropriate technique to the process to provide a product more compatible with the environment. Therefore, we are interested in this research in two aspects: improving production and reducing environmental pollution. It was found in the research that the application of the alkylating technique ? project led to the reduction of solid pollutants (GWG) almost (zero) by dispensing with the use of furnaces that produce the material (carbon steel). This means that (SWG = Zero), as well as a decrease in water consumption by (31741,920) barrels per year.
