【摘要】 石油化工行业是我国国民经济的支柱产业,也是我国工业界的污染大户。同时,石化企业也是一种安全环保要求高的企业,生产过程存在多种易燃、易爆和有毒的物质,随着石油化工行业生产日益向高温、高压和大型化发展,生产的安全问题显得尤其重要。因此,对石化企业的重点污染源装置进行安全评价,这对于保障员工生命财产安全,加强石化企业安全环保资源的有效管理,促进企业安全生产和持续、稳定地发展具有重要的意义。 本课题是以广州石化二万吨硫磺回收装置为例建立一套安全评价系统。本文首先对装置的工艺流程和化学物质进行了简要的分析,并对每一个子系统的关键设备可能出现的安全故障进行了详细分析。然后,介绍了改进了评分标准的安全检查表法和经典的道化学公司火灾、爆炸指数法的基本内容,再结合二万吨硫磺回收装置做了应用研究,建立了该装置的安全检查条款库、问题知识库和措施知识库,为其它石化企业关键装置安全评价系统知识库的建立提供了有益的参考。 另外,本文根据用户的实际需求,按照软件工程的一般要求,从系统的需求分析、系统建模、系统设计到系统实现逐步的阐述本系统的开发过程与实现方法,开发出了一套基于B/S模式的安全评价系统。该系统与装置的日常安全检查计划结合在一起,在实施安全大检查的过程中实现对装置的安全评价,把安全评价系统提升至管理的层面,实现了应用的创新。 最后,对本文所做的研究工作进行了总结,并对安全评价系统进一步的研究进行了展望,指出了需要完善和改进的地方。更多还原

【Abstract】 Petrochemical industry is the mainstay of our national economy and it is one of the most contaminative industries. There are some materials that are poisonous or easily to burn and blast during the process of production. As petrochemical industry developing into high temperature, high pressure and great scale, the problem of safety manufacture becomes more important. Therefore, it is more important to develop risk assessment on key equipments in petrochemical industry, because it can protect people’ s life and property, strengthen the management of safe and environment protecting resource, and guarantee safely manufacturing and steadily developing of industry.This thesis takes the twenty-thousand-ton sulphur recovery device as the research object, and the aim is to build one risk assessment system. In the thesis, firstly we analyze the craft process of the device and expatiate the safety faults in key equipments of every subsystem which maybe to appear. We introduce basic content of safety check form that is improved graded standards and classical dow’ s fire and explosion index V7. 0. And then, we make application research integrates with the twenty-thousand-ton sulphur recovery device, set up items database of safety check items and faults database and measures database. It provides useful references for setting up repository of risk assessment system in other petrochemical key equipments.In addition, according to the consumer’ s practical demand and normal request of software, it expatiates about the analysis, modeling and design of the system, of course, including the realization of a B/S mode risk assessment system. This system hangstogether daily check plan of the equipment, and finishs the equipment risk assessment in the process of implementing safety check. The risk assessment system is stepped up to the layer of management. Moreover, it realizes the innovation of applications. At last, the research is summarized, and the future further research is prospected in this thesis. In the same time something is pointed out that needs to be improved and perfected .更多还原
