【摘要】：为了减少事故的发生、降低人员和财产的损失，本文详细介绍了系统安全分析方法——危险与可操作性分析（HAZOP）的原理、方法和流程，，利用HAZOP研究方法能够辨识由于偏离而构成的危险因素。利用HAZOP方法辨识出现偏差的可能原因、后果，以及现有安全措施是否能够满足安全需要，如果不能要增加建议安全措施提高系统的安全水平。同时基于HAZOP研究方法对系统的分析结果，对系统进行事故隐患排查管理。识别出系统中存在的事故隐患，建立事故隐患排查单。根据一般事故隐患和重大事故隐患的分类标准，从两方面对事故隐患进行排查，分别从隐患可能导致事故的后果严重性和事故隐患的整改难度进行分析。通过进一步分析，可以从事故发生造成的人员伤亡、事故发生造成的财产损失、隐患整改的经济投入、隐患整改的技术支持、隐患整改的时效性五个方面对系统内识别出的隐患进行排查管理。借助层次分析法计算五个因素的权重，并建立的了公式R=Sω1+Pω2+Fω3+Iω4+Tω5计算事故隐患的风险，确定一般事故隐患和重大事故隐患的界限值，从而识别出系统中存在的哪些是一般事故隐患，哪些是重大事故隐患。以国内某煤化工企业煤制甲醇气化车间的四个分析部分作为分析对象，将HAZOP研究方法和事故隐患排查管理应用于企业实例中，分析气化系统内的偏差。并以HAZOP分析结果为基础，对分析对象的设备、装置、设施等进行事故隐患排查管理，识别其中的事故隐患，并利用专家打分和建立公式R=Sω1+Pω2+Fω3+Iω4+Tω5计算事故隐患的风险值，辨别一般事故隐患和重大事故隐患。事故隐患排查可以使企业的安全管理更有针对性和有效性，对识别出的事故隐患给出相应的消除、控制措施，对重大事故隐患应立即整改，监测整改的情况，提升企业的安全水平。
[Abstract]:In order to reduce the occurrence of accidents and the loss of personnel and property, this paper introduces in detail the principle, method and flow of the system safety analysis method-Hazard and maneuverability Analysis (HAZOP). The HAZOP method can be used to identify the risk factors caused by deviation. HAZOP method is used to identify the possible causes and consequences of deviation, as well as whether the existing security measures can meet the security needs, and if the proposed security measures cannot be added to improve the safety level of the system. At the same time, based on the analysis results of HAZOP research method, the system is investigated and managed. Identify the hidden trouble in the system, and set up the check list of the hidden trouble. According to the classification standard of the hidden trouble of common accident and the hidden trouble of major accident, the investigation of the hidden trouble of accident is carried out from two aspects, and the seriousness of the consequence of the hidden trouble and the difficulty of rectifying the hidden trouble of accident are analyzed respectively. Through further analysis, the casualties caused by the accident, the loss of property caused by the accident, the economic input for the rectification of the hidden danger, and the technical support for the rectification of the hidden danger can be obtained. Hidden trouble rectification of the effectiveness of five aspects of the system identified hidden trouble management. With the help of analytic hierarchy process (AHP), the weights of the five factors are calculated, and the formula RCS 蠅 1P 蠅 2F 蠅 3I 蠅 4T 蠅 5 is established to calculate the risk of the hidden trouble of the accident, and to determine the limit value of the hidden trouble of the general accident and the hidden trouble of the major accident. In order to identify the system which is common accident hidden trouble, which is a major accident hidden danger. Taking the four analysis parts of methanol gasification workshop of a coal chemical enterprise in China as the object of analysis, the HAZOP research method and accident hidden danger investigation and management are applied to the enterprise example to analyze the deviation in the gasification system. Based on the results of HAZOP analysis, the equipment, devices and facilities of the object of analysis are investigated and managed to identify the hidden troubles, and the formula of S 蠅 1P 蠅 2F 蠅 3I 蠅 4T 蠅 5 is established to calculate the risk value of the hidden trouble by using the expert scoring and establishing the formula RKS 蠅 1P 蠅 2F 蠅 3I 蠅 4T 蠅 5. Distinguish between common accident hidden trouble and major accident hidden trouble. The investigation of hidden dangers of accidents can make the safety management of enterprises more pertinent and effective, and give the corresponding elimination and control measures for the hidden dangers of accidents identified, and immediately rectify and monitor the situation of the hidden dangers of major accidents. Improve the safety level of enterprises.
