    Optimization of light hydrocarbons recovery from the Magnaforming stabilizer (100-C-4) bottom product of U100, RA1K using Aspen HYSYS
    (NATIONAL HIGHER SCHOOL OF TECHNOLOGY AND ENGINEERING -ANNABA, 2024) ZAIDI Ghozlane Rihane; BRAHMI Nour El Imene; BENDEBANE Salima (Encadrant)
    This work presents the simulation and optimization of the stripping system of Magnaforming unit (U100) at Skikda’s Refinery 1, with the aim of minimizing the light hydrocarbon fraction in the treated naphtha produced from catalytic reforming. This study will explore analytical methods for characterizing petroleum products, including ASTM D86 distillation and ASTM D6729 gas chromatography, as well as numerical methods for characterizing petroleum mixtures and modeling the unit operation used (distillation). The simulations and the results were generated using ASPEN HYSYS software based on design data and the optimization was carried out using the real plant operating conditions and composition.

    Planning biodiesel production from waste vegetable oils
    (NATIONAL HIGHER SCHOOL OF TECHNOLOGY AND ENGINEERING -ANNABA, 2024) BRAHMI Nour El Imene; BENDEBANE Salima (Encadrant)
    Biodiesel is a renewable fuel made from animal fats and vegetable oils. Heterogeneous nanocatalysts are increasingly used in its production due to their efficiency and ability to reduce processing costs. This study investigates the use of waste cooking oil to produce biodiesel, by developing in a first step a solid and stable catalyst. To this end, a mixing plan application was considered. In the second part, biodiesel production was optimized using response surface methodology (RSM). A maximum yield of 97.1% was achieved with an ethanol/oil ratio of 10.83:1, a catalyst concentration of 3% and a reaction time of 3 hours. The biodiesel produced was also found to conform to ASTM D6571 standards. So, it can be said that the synthesized mixed oxide catalyst has a high efficiency for the production of biodiesel from waste cooking oil. The catalysts were characterized by various techniques, including FTIR and SEM-EDS.
