Chemical engineering equipment hazard and operability (Hazop) analysis method and system

Abstract

The invention discloses a chemical engineering equipment hazard and operability (Hazop) analysis method and system. The system comprises a basic information configuration module, an information input module, an expert database intelligent analysis module, a result output module and a report generation module, and is specialized software for carrying out Hazop analysis in the chemical engineering production process. The information input module comprises input of data such as physical property data, design parameters and a technological process; the expert database intelligent analysis module carries out analysis and processing on the data of specific equipment, determines a process node and deviation, recognizes a risk existing reason and analyzes the consequence. The result output module automatically generates a Hazop analysis table in allusion to actual conditions of the equipment, performs discussion on results, protection measures and the like, and realizes functions of intelligent judgment, screening, statistics, automatic risk grade recognition and graph association display. The report generation module generates a report automatically according to customer requirements. The method disclosed by the invention improves the quality of HAZOP analysis and the safety and the operability of the equipment, improves the efficiency and saves the time. In addition, the method is comprehensive in analysis, and reduces the accident probability of production equipment.

Description

technical field [0001] The invention relates to a hazard and operability (Hazop) analysis method and system of a chemical device, which is a supporting software for professionally performing Hazop analysis in the chemical production process. The method realizes the automation and intelligence of the Hazop analysis. Background technique [0002] Hazop analysis requires a large amount of empirical knowledge and non-quantitative knowledge that are difficult to model and formulate. The entire analysis process requires a large amount of knowledge and document data in design, operation, control, etc., and requires divergent thinking and consideration of various possibilities. Sex, so it is also called a "brainstorming" type of activity. Hazop analysis generally requires an experienced team leader who has a deep understanding of the analyzed process to ask questions, guide the team members to conduct analysis, and often temporarily requires the active participation of various perso...

AI Technical Summary

Problems solved by technology

Due to the knowledge-intensive characteristics of Hazop analysis, there is no effective automated analysis software that can replace manual Hazop analysis and is widely used at home and abroad.

Artificial Hazop analysis technology plays an important role in the industrial field, but it has certain limitations, as shown in: 1) It strongly depends on the ability and experience of the team leader; 2) Artificial Hazop analysis needs to deal with a large amount of data, Information and calculation are time-consuming and labor-intensive; 3) When an expert group discusses issues together for a long time, it is easy to fall into inertial thinking; 4) It is difficult for the human brain to traverse all possibilities, and it is difficult to guarantee the consistency and completeness of the analysis
