【摘要】：本文介绍的液态烃具有极高的易燃易爆性，分布于炼油厂的主要装置，本文以吉林石化公司炼油厂液态烃系统为例，旨在通过对吉林石化公司炼油厂液态烃系统运行状况进行全方位的安全分析评价，制定安全稳定运行的综合技术措施，确保液态烃系统安全稳定长周期运行。从本篇论文三方面进行阐述：第一部分说明炼油厂基本的液态烃系统构成及液态烃在炼油厂的分布情况，主要目的是阐述在应用系统安全分析方法时，要根据液态烃系统中不同的装置和单元以及分析评价的目的，采用不同的适用的评价方法，同时通过应用系统安全分析评价方法识别出炼油厂液态烃系统的主要危险源和危害，为下一步采用和制定综合安全技术措施提供依据。第二部分为液态烃系统的主要事故类型和原因分析，在第一部分液态烃系统危险源分析的基础上进行事故类型和原因分析，可以看出炼油厂各液态烃的生产储存单元均构成重大危险源，而且系统的设备管线泄漏是造成事故的主要原因，此部分主要结合国内外相关事故案例进行事故类型和原因分析。第三部分为液态烃系统安全稳定运行综合技术措施，从设计、施工、日常运行管理、设备维护、应急处理等几方面阐述保证液态烃系统安全稳定运行的安全技术措施。 液态烃系统安全稳定长周期运行对炼油厂具有重大意义，是工厂获得长期良好的经济效益和社会效益的重要保证。本文通过对吉林石化公司炼油厂液态烃系统运行状况的调查、分析，运用系统安全评价的方法，进行危险、有害因素的识别及其危险度的评价，查找该系统生产运行中存在的隐患并判定其危险程度，提出合理可行的安全对策及建议，以提高液态烃系统的本质安全程度，使系统在生产运行期内的安全风险控制在安全、合理、可接受的程度内。炼油厂液态烃系统存在的危害是巨大的，但通过科学有效的管理，采取可靠的安全技术措施，，上述危害是可以消除和控制的，完全可以实现液态烃系统安全、稳定、长周期运行。
[Abstract]:The liquid hydrocarbon introduced in this paper has very high flammable and explosive properties and is distributed in the main units of the refinery. This paper takes the liquid hydrocarbon system in the refinery of Jilin Petrochemical Company as an example. The purpose of this paper is to make comprehensive technical measures for the safe and stable operation of the liquid hydrocarbon system in Jilin Petrochemical Company through the comprehensive safety analysis and evaluation of the operation condition of the liquid hydrocarbon system in order to ensure the safe and stable long period operation of the liquid hydrocarbon system. In the first part, the composition of the basic liquid hydrocarbon system and the distribution of the liquid hydrocarbon in the refinery are described. The main purpose is to explain the application of the system safety analysis method. According to the different units and units in the liquid hydrocarbon system and the purpose of the analysis and evaluation, different applicable evaluation methods should be adopted. At the same time, the main dangerous sources and hazards of the liquid hydrocarbon system in the refinery should be identified by the application of the system safety analysis and evaluation method. For the next step to adopt and formulate comprehensive safety technical measures to provide the basis. The second part is the main accident type and cause analysis of liquid hydrocarbon system. Based on the analysis of hazard source of liquid hydrocarbon system in the first part, the accident type and cause analysis are carried out. It can be seen that every production and storage unit of liquid hydrocarbon in refinery is a major hazard source, and the leakage of equipment and pipeline in the system is the main cause of the accident. This part mainly analyzes the type and cause of the accident combined with the related accident cases at home and abroad. The third part is the comprehensive technical measures for the safe and stable operation of the liquid hydrocarbon system. From the aspects of design, construction, daily operation management, equipment maintenance, emergency treatment and so on, the paper expounds the safety technical measures to ensure the safe and stable operation of the liquid hydrocarbon system. The safe and stable long period operation of liquid hydrocarbon system is of great significance to the refinery and is an important guarantee for the plant to obtain long-term good economic and social benefits. Based on the investigation and analysis of the operation status of the liquid hydrocarbon system in Jilin Petrochemical Company Refinery, the method of system safety evaluation is used to identify the dangerous and harmful factors and to evaluate the risk degree. In order to improve the essential safety degree of liquid hydrocarbon system, the hidden trouble in production and operation of the system is found out and the dangerous degree is judged. The reasonable and feasible safety countermeasures and suggestions are put forward in order to improve the essential safety degree of the liquid hydrocarbon system and to control the safety risk of the system in the production and operation period. Within a reasonable and acceptable degree. The harm of liquid hydrocarbon system in refinery is great, but through scientific and effective management and reliable safety and technical measures, the above hazards can be eliminated and controlled, and the safety and stability of liquid hydrocarbon system can be completely realized. Long period operation.
