This study was carried out at Gas platform (unit No 30) of Skikda refinery Algeria, with the aim of predicting and estimating the effects of major explosions in the propane and butane Splitter column and estimating the possible human and environmental consequences of the containment loss. The methodology developed here is based on a combination of HAZOP presentation and PHAST tool. First, HAZOP is used to capture the responsible derivations of operating parameters to produce the worst consequences. Related Causes, safety barriers and some recommendations are carried out in a HAZOP sheet which represents all of that. Then the major scenarios detected by the worst consequences have been studied and modeled by PHAST software. The modeling process is completed by simulating the principal effects (Jetfire, BLEVE, UVCE) resulting from two scenarios in the form of two potential leaks on the bottom and the head of a gas separator column containing butane and propane respectively. The results are shown on the region map to indicate the exact threaten zones. Finally, a comparison in terms of effects between the two scenarios is performed and some conclusions are extracted.   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/176 10.51485/ajss.v7i4.176 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/176/151 Rights Information about rights held in and over the resource Copyright (c) 2022 Amina BENAISSA, Mohyiddine HAMAIDIA, Malika KHELFAOUI, Wafia BENHAMLAOUI 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. 4 (2022); 156-163 2676-1548 2543-3792 10.51485/ajss.v7i4 Subject The topic of the resource Risk Threaten zones HAZOP PHAST Major scenarios Title A name given to the resource Risk Analysis and Assessment of Butane-Propane Splitter Column in the Skikda Refinery Petroleum Plant 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.

The proposed UPQC is designed by the integration of shunt and series APFs (Active Power Filters) sharing a common dc bus capacitor. The dc voltage is maintained constant using proportional integral voltage controller. To get the reference signals for shunt and series APFs, synchronous current detection method (SCD) and instantaneous reactive power (PQ) strategies are adopted. These reference signals are derived from the control algorithm and injected in LS-SPWM (Level Shifted-Sin Pulse Width Modulation) controllers to generate the switching signals. The performance of proposed UPQC system is evaluated using MATLAB-Simulink software and SimPowerSystem Toolbox for all voltage disturbances compensation. The simulation results demonstrate the effectiveness of proposed UPQC system to improve the power quality at the common connection point of the non-linear load in steady and transient conditions operation.

Creator An entity primarily responsible for making the resource Ahcene, Fazia Bentarzi, Hamid Date A point or period of time associated with an event in the lifecycle of the resource 2022-09-30 Description An account of the resource As the power system becomes smarter, the difficulty of control is also increasing. Since, load frequency and voltage stability is an important power quality index in power system, any sudden load disturbance will cause the system load frequency and voltage deviation, and as the power system becomes more complex. However, the stability and reliability of the smart power grid are facing great challenges caused by the intermittency and randomness of renewable energies. Nowadays, it is necessary to find a more appropriate control strategy and techniques. Due to the superior anti-interference and anti-coupling ability of the active disturbance rejection control (ADRC), novel applications of this control technique have been developed in smart system. This paper presents firstly a synthesis of ADRC and then it discusses some important applications of ADRC in this field.

Traditional electricalenergy generation approaches which usually rely on oil and its derivatives, produce different kinds of pollution in addition to being expensive to implement and maintain. And most important, they are exhaustible on the long run. The sun is an unlimited source of energy for humanity around the world and a competitive energy with strong potential. The solar systems technology offers a promising method for the large scale use of solar energy in the southern zone of Algeria. The magnitude of solar radiation is the most important parameter for sizing these systems. This study presents a techno-economic feasibility evaluation for an installation of a stand-alone PV system which covers the electric demand of 20 houses in the province of Tindouf located in the South-West of Algeria. The aim is to select the appropriate components and see the results of the simulation using the hybrid simulator iHOGA, which include the total cost, CO2 emissions and their impact on the environment.

The proposed UPQC is able to mitigate source current harmonics and compensate all voltage disturbances. It is designed by the integration of series and shunt active filters (AFs) sharing a common DC bus capacitor. The DC voltage is maintained constant using proportional integral voltage controller. The synchronous reference frame (SRF) theory is used to get the reference signals for the shunt APF and the power reactive theory (P-Q theory) for the series APF.Conventional control schemes require complex calculations, the use of intelligent systems help to reduce the control system size and the operation complexity.

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.
