Item type:Item, Etude CFD de l'écoulement aérodynamique autourd'une hélice d'avion en mouvement(Université Ammar Telidji Faculté de technologie Département de Génie Mécanique, 2026) BENYETTOU ABDENOURELHACHEMI; BASLIMAN MOHAMMED YOUCEF; Hamdi NassereddineThis thesis presents a numerical study of the aerodynamic flow around a moving aircraft propeller similar to that of the 8-bladed Airbus A400M cargo aircraft. The work begins with the propeller design using SolidWorks CAD software. Calculations and mesh generation are performed using ANSYS-CFX software with the k-ω SST turbulence model, suitable for this type of flow, with a propeller rotation speed of 500 rpm and an aircraft speed of 432 km/h. The results provide the behavior of the streamlines and the pressure field distribution on the blades. The results obtained include a thrust of 49,581 N and an engine torque of 120,597 N·m, with relatively acceptable error rates compared to the values given in the technical specifications for this type of aircraft, thus confirming the validity of the adopted methodology.Item type:Item, Identification, Évaluation et Amélioration des Éléments Importants pour la Sécurité (EIPS) dans les Installations Classées Hydrocarbures Application au Four Rebouilleur du Module MPP0 — SONATRACH Hassi R'Mel(Université Amar Thelidji- Laghouat FACULTE : TECHNOLOGIE DEPARTEMENT : GÉNIE DES PROCÉDÉS, 2026) ANNAG Zineb; ALLALI Amina; HASSANI MouaadhThis thesis focuses on the application of the Safety Important Elements (SIE/EIPS) methodology to classified hydrocarbon installations, using the H401 reboiler furnace at the MPP0 production module of the Hassi R'Mel gas complex (SONATRACH, Algeria) as a case study. The research is structured in three chapters. The first chapter establishes the conceptual, regulatory and methodological foundations of the EIPS approach, drawing on the Algerian regulatory framework (Law No. 03-10 of July 19, 2003, Executive Decrees No. 06- 198 and 21-331) and international normative references (IEC 61511:2016, IEC 61508:2010, OLF 070 guideline, SEVESO III Directive). It defines four EIPS classification typologies by safety function, physical nature, hazard controlled and SIL level and formalizes a fivephase identification and management methodology. The second chapter applies this methodology to the H401 furnace: characterization of six major risk categories, structural decomposition into four sub-systems (feed, control, alarm, SIS/ESD emergency shutdown), identification and classification of seven EIPS, and qualitative assessment of the ESD system Safety Integrity Level (SIL) using Fault Tree Analysis (FTA) with the GRIF software. Results reveal that the 1oo1 non-dedicated architecture of SIS sensors is the limiting factor preventing attainment of the target SIL 2 level. The third chapter formalizes seven rated reservations (two Critical, three Major, two Minor) and develops an 18-month structured corrective action plan (CAP), incorporating alternative EIPS, designated responsible parties and deadlines. Post-CAP re-evaluation projects the H401 ESD system toward the global SIL 2 target level, pending quantitative validation and third-party independent certification.Item type:Item, ظاهرة التلوث البيئي في الجزائر واليات الحد منها دراسة حالة قطاع المحروقات بشركةسوناطراك حاسي الرمل(Bibliothèque Centrale-Université Amar Thlidji -Laghouat, 2014) صفية علاوي; ا.د ابراهيم بورنانFocusing on industrial activities and its effects on environment because of dangerous gas, solid or liquid industrial wastes has become a source of industrial pollution which negatively affects environment, human beings and living creatures in Algeria and the whole word. This has given birth to main problematic as follows: What is the reality of environment? What are the problems of pollution of the Algerian hydrocarbons sector? And how can we face them? In order to deal with the main problematic, we have defined the framework of the study as follows: cognitive framework: To look over biography through description and analysis. The situational framework: This deals with the field aspect of SONATRACH Company, and notably the regional head management of hassi R’mel. The temporal framework: We have tried to narrow down this study to the first decade of this century, and relied on using the two methods: analytical and descriptive from the available data, statistics, official indications issued by the company, other world organizations specialized in environment, and the hydrocarbons sector, in addition to the inductive and deductive methods with the help of indications and statistics which support analysis, and finally, we have adopted the study case of SONATRACH company. The important results are as follows: -In spite of the importance given to this sector, its negative influence on environment during the different hydrocarbons industry stages has become a source of environmental pollution, especially water, air and soil pollution, and therefore, these effects must be removed before embarking on transport and transformation. -The adoption of an environment policy by SONATRACH has made it able to improve the implementation of safety, health and environment system. The effect of hydrocarbons extraction and their transport to the surrounding environment is also the responsiblity of multinational companies as they are greatly responsible for environment protection either from the point of view of international law or legislations and regulation.
