Abstract
This research aims to apply the life cycle assessment to determine the environment impacts of oil products (diesel, gasoline, light gas oil, fuel oil, liquid gas, kerosene, jet fuel) in Daura Refinery on environmental using Ready program Simapro 7 by adopting a case study methodology. The research represented a problem increasing pollution rates caused by oil products during the refining processes, and the resulting impacts in the surrounding environment, because of gases and vapors emissions that affect human health, animal and plant. Results confirmed that the gasoline product is the product of the most influential and damaging, as it is the product the light gas oil least influential and damaging than the oil products, As different categories ratios impact depending on the product and the stages of production of each product,
