AbstractIn the oil and gas industry, it is common to use gas liquefaction that allows storage and transport of large quantities of LNG and LPG. One of the main disadvantages of this storage mode is the BLEVE risk, which remains a major concern for risk decision-makers. In order to prevent the occurrence of this risk and reduce its impact, risk analysts often use quantitative risk analysis (QRA), which is based on the understanding and quantification of the accidental phenomena and their consequences (overpressure, thermal radiation, toxicity dose). QRA is a rigorous and advanced approach that requires reliable data in order to obtain a good estimate and control of risks. The main objective of this paper (Part II) is to integrate the Sedov-Taylor model developed in Part I into the QRA approach in order to evaluate BLEVE blast effect, and illustrate it with a case study on a pressurized LPG accumulator located in the MPP3-plant of SONATRACH company in the Hassi R’Mel gas field (the largest gas field in Algeria). A parametric analysis of the fuel mass, temperature at failure and rupture pressure is carried out to study their influence on the evolution of BLEVE overpressure. In addition, the evaluation of BLEVE thermal effect is performed in order to better realize an exhaustive QRA. Through this application, the results show the great relevance of the Sedov-Taylor model in the consequence analysis and also in the development of process safety recommendations.

Quaternary fluviatile terraces of the Oued El Gourzi (Batna, NE Algeria): sedimentology and characteristics of the depositional environment, in

Publisher's VersionAbstract
Field observations and sedimentological analyses of alluvial terraces of the O. Gourzi (Batna, NE Algeria) lead us to consider sediments as dominated by clayey and silty-sandy fractions overlain by gravel and calcareous coarser fractions. Moderate CaO3 contents would have resulted from the dissolution of the nearby carbonate relieves. They are mainly composed of Maastrichtian limestones. The distribution of the mineral fraction led us to identify 07 levels including horizons of coarse fractions alternating with layers rich in sand and silt with a roughly constant clay fraction through the stratigraphic column. Kurtosis values, frequency histograms of a prokurtic type, rarily mesokurtic, mark a constant power mode for the transport agent. Classification indices indicate poorly- to moderately sorted material, indicating a turbiditic depositional environment. Quartz grain nature and morphoscopy refer to Miocene sandstones as a potential origin. The ferruginous coating is due to the initiating pedogenesis.
