However, the analysis of simulation using realistic computer codes like RELAP5/Mod3.2 will help understand thermal-hydraulic behavior of an installation during normal and accidental conditions. In a steam boiler operation, it is very important to evaluate numerous accident scenarios under real plant conditions. One of the main accidental transients is tube rupture of steam boiler. The main objective of this study consists toinvestigate the behavior of an industrial steam boiler installed in the complex of natural gas liquefaction (LNG) at Skikda in Algeria during feed water line break accident. A RELAP5 model was set up to simulate the entire system, the model represents all steam boiler components to be suitable for the analysis of the several accidents. The control and regulation systems are also considered. The model was qualified against the steam boiler data at steady-state conditions. As seen from the results, a good agreement was obtained. The transient simulation results show that the thermal-hydraulic code correctly predicts the behavior of the main steam boiler parameters and how the control system, when required, can successfully mitigate the accident.

Therefore, it assembles critical equipment that can cause hazards to personnel, assets, and the environment. This paper presents a risk assessment for an LNG storage tank release in an LNG terminal. Risk assessment was conducted by applying a HAZOP study, Bowtie analysis, fault tree analysis, and ALOHA (Areal Locations of Hazardous Atmospheres) simulation. The results were to identify causes, consequences, and safeguards of hazards related to over and under pressure in an LNG storage tank. Moreover, a bowtie analysis was established for LNG loss of containment (LOC) from flammable liquids storage tanks. In addition, a fault tree analysis was presented to identify the causes of tank failure considering pressure hazards. Finally, the consequences of LNG released from the storage tank are simulated using the ALOHA software Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context https://ajss.dz/index.php/ajss/article/view/162 10.51485/ajss.v7i2.162 Language A language of the resource eng Publisher An entity responsible for making the resource available Laboratory of Signals and Systems, Algeria Relation A related resource https://ajss.dz/index.php/ajss/article/view/162/139 Rights Information about rights held in and over the resource Copyright (c) 2022 Sarra CHEBLI , Chérif TOLBA , Youcef ZENNIR https://creativecommons.org/licenses/by-nc/4.0 Source A related resource from which the described resource is derived Algerian Journal of Signals and Systems ; Vol. 7 No. 2 (2022): AJSS; 53-60 2676-1548 2543-3792 10.51485/ajss.v7i2 Subject The topic of the resource LNG terminal LNG storage tank HAZOP Bowtie analysis Fault tree analysis ALOHA LOC Title A name given to the resource Risk Assessment of an LNG Storage Tank Release: Case study of LNG storage unit in Skikda LNG terminal Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

First, Lyapunov-Krasovskii functional with simple and double-integral terms is constructed considering both upper and lower bounds of network delay. Then, less conservative Linear Matrix Inequalities (LMIs) stability conditions are established using null terms to introduce free weighting matrices based on the Leibniz-Newton formula. Furthermore, Finsler's lemma is used for the relaxation of the obtained LMI's stability conditions using slack decision variables. It is also used to decouple Lyapunov-Krasovskii matrices from the system ones. The application of the proposed approach for different NCSs gives higher upper delay bounds compared with other methods.

Creator An entity primarily responsible for making the resource LARIT, Khalid ZENNIR, Youcef RODRIGUEZ, Manuel Date A point or period of time associated with an event in the lifecycle of the resource 2022-03-31 Description An account of the resource In steelworks, due to the complex nature of operations, systems, procedures and methods always involve a certain amount of risk. It is not possible to eliminate all hazards, so the goal is to eliminate and/or control high and critical potential hazards and reduce the rest of the hazards to the lowest reasonable risk level in order to protect workers and equipment against damage and to ensure the proper functioning of the production chain. Risk assessment involves identifying and analyzing the hazards, the sequences of events leading to the hazards, and the risk of hazardous events. The objective of this work is the functional modeling of steelworks of the steel complex of EL-MILIA JIJEL (ALGERIAN QATARI STEEL) and the application of risk analysis methods (STPA, D-Higraph) to identify, analyze the dangers and recommend the necessary control measures for them.
