    Optimisation de la production d'une raffinerie Cas d’étude : Raffinerie d’Asbaâ Adrar Sonatrach

    This thesis aims to improve the production planning of the Asbaâ Adrar refinery, a vital facility for supplying petroleum products in southern and southwestern Algeria. Using a linear programming model, the thesis seeks to maximize the refining margin while respecting constraints related to material balance, quality (octane number, Reid vapor pressure), and capacity (54,000 tons/month of crude oil). The model was implemented in MATLAB, resulting in a 19.5% increase in monthly revenues and a 44.8% increase in net profit margin. The thesis outlines the fundamentals of refining, presents the refinery (with a capacity of 600,000 tons/year, and units for distillation, reforming, and cracking), introduces linear programming, and formulates the optimization model. Despite its limitations (lack of yield constraints, static model), it offers a reusable methodology for other refineries and contributes to scientific research by linking theory with Algeria's industrial challenges.
