    Removal of hydrocarbons and heavy metals from petroleum water by modern green nanotechnology methods
    (2023) Bouafia, Abderrhmane; Meneceur, Souhaila; Chami, Souheyla; Laouini, Salah Eddine; Daoudi, Henda; Legmairi, Souheila; Menaa, Farid
    Considered heavy metals, such as As(III), Bi(II), Cd(II), Cr(VI), Mn(II), Mo(II), Ni(II), Pb(II), Sb(III), Se(-II), Zn(II), and contaminating chemical compounds (monocyclic aromatic hydrocarbons such as phenolic or polycyclic derivatives) in wastewater (petrochemical industries: oil and gas production plants) are currently a major concern in environmental toxicology due to their toxic efects on aquatic and terrestrial life. In order to maintain biodiversity, hydrosphere ecosystems, and people, it is crucial to remove these heavy metals and polluting chemical compounds from the watery environment. In this study, diferent Nanoparticles (α-Fe2O3, CuO, and ZnO) were synthesized by green synthesis method using Portulaca oleracea leaf extract and characterized by UV–Vis spectrophotometers, FTIR spectroscopy, X-Ray Difraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) techniques in order to investigate morphology, composition, and crystalline structure of NPs, these were then used as adsorbent for the removal of As(III), Bi(II), Cd(II), Cr(VI), Mn(II), Mo(II), Ni(II), Pb(II), Sb(III), Se(-II), and Zn(II) from wastewater, and removal efciencies of were obtained 100% under optimal conditions

    Fiabilist and economic approaches to optimisation of the renewal of hydrocarbons transporting pipelines
    (2013) Abdelbaki, Noureddine; Gaceb, Mohamed; Bouali, Elahhmoune; Bettayeb, Mourad; Bouzid, Rachid
    Problems of hydrocarbons transporting pipelines agi ng and rehabilitation are currently a major concern for operators of such installations. Rehabilitating and insuring hydrocarbons transporting pipelines, require interventions, such as the renovation of existing lines, the replacement of some pipelines with new ones, in order to meet the growing demand of consumers and improve the supply reliability. In this context, a decision to repair or replace a section of pipe must co mbine both a technical analysis of failures and sound economic analysis of the choice of possible interventions , which is the purpose of this study, dedicated to research and policy determination of repair and replac ement of aged pipe sections, taking into account the factors mentioned above, and based on significant feedback

    Essential oil of cytisus triflorus L'Her
    (2013) Aourahoum, K.; Aissaoui, M.; Fazouane, F.; Larit, F.; Chalard, P.; Chalchat, J.C.; Figueredo, G.
    The essential oil of Cytisus triflorus L'Her., a Mediterranean species was obtained by steam distillation and identified by GC and GC-MS. 61 compounds were determined. The oxygenated terpenoidic components constituted the most important fraction (64%) followed by the fatty acids (8.2%) and the hydrocarbonated fractions (10.7%)
