conventional HAZOP study are its timeconsuming character and high cost. The principal objective of this paper is to present a new methodology for hazard identification of a selected chemical production process. Modelbased HAZOP study is a very robust tool for predicting a systems response to deviations from design or operation conditions.

Finally, we build ISK triples and store them in the Neo4j graph database. We take indirect coal liquefaction process as a case study to develop ISKG, and its oriented applications can optimize HAZOP and mine the potential of ISK, which is of great significance to improve the security of the system and enhance prevention awareness for people.

HAZOP can identify production plant design and operation and maintenance procedures (VIEGAS et al., 2020). Ultimately improve the safety and operability of the device process, and provide a basis for making basic disaster prevention measures and emergency plans for decisionmaking. HAZOP analysis can be applied to all stages of the system life ...

1. Introduction. Hazard and operability study (HAZOP) is applied worldwide as one of the process hazard analysis (PHA) techniques for processing plants [].HAZOP is implemented on a legal basis for the licensing of processing plants in accordance with the process safety management of the US Occupational Safety and Health Administration (OSHA) and the Seveso provisions of the EU [].

Abstract: In order to prevent any accident from happening, a safety assessment modeling approach combined with analytical hierarchy process (AHP), signed directed graph (SDG) and hazard and operability (HAZOP) is proposed for thermal power plants in this paper. AHP is used to divide the production equipments for thermal power plants into several hierarchies and it can simplify the modeling ...

Process HAZOP Procedure HAZOP Reporting Conclusions Marvin Rausand, October 7, 2005 System Reliability Theory (2nd ed), Wiley, 2004 4 / 44 The HAZOP study should preferably be carried out as early in the design phase as possible to have influence on the design. On the other hand; to carry out a HAZOP we need a rather complete design.

The Hazard and Operability Study (HAZOP) methodology is considered one of the most effective techniques for risk analysis, developed fundamentally to provide regular processes with reduced risks that aim to guarantee the safety of activities and the operability of the production units. The study aims to apply the HAZOP methodology in process and safety operations in the oil production industry.

During the entire life cycle of a chemical process plant, safety assessments are conducted during the process and plant design phase, plant revisions or in order to comply with amended legal regulations. Hazard and Operability (HAZOP) studies are conducted to identify and assess hazards and malfunctions that arise from processes and process plants.

Modular process plants are small or medium scale plants which consist of separately engineered and automated modules. To speed up the start of production, a modular process plant is composed from several of such modules. Nowadays, safety engineering refers to the whole process plant, is very individual, time consuming, and hardly integrated. For safe modular process plants, the safety ...

A HAZOP study is a highly disciplined procedure aimed at identifying how a process may deviate from its design intention. This method is able to distinguish between hazard (any operation, that could cause a catastrophic release or that could result in harm to workers) and operability (any operation within the project that could cause a plant ...
