第1页略阳钢铁制氧站生产系统安全性分析（制氧工艺）班级：安全1201学生姓名：指导教师：摘要：随着科学技术的发展，对氧气产品的需求量在不断增长，制氧企业的生产规模也在不断扩大。氧气的性质决定了氧气在生产、储存过程中存在着燃烧、爆炸等固有危险性，而制氧企业设备大型化、高度连续性、自动化程度高、高危险性的生产特点又决定了它具有许多潜在的危险性。因此，在制氧企业中实现安全评价是十分必要的。本文通过安全评价的相关知识对略阳钢厂制氧站进行安全风险评价，对生产环节进行系统分析、辨别其存在的危险有害因素，并对该项目的制氧工艺进行了火灾爆炸指数评价，通过计算该工艺火灾、爆炸指数，评价火灾爆炸固有危险性等级，最终计算出安全措施补偿系数、最大可能财产损失等。并提出相关的安全措施，力图减少制氧站事故的发生，避免制氧站生产中人的伤害，降低财产的损失。关键词：安全评价，DOW，制氧工艺，火灾、爆炸危险指数第2页AnalysisoftheproductionsafetysystemofLueyangIron&steeloxygenstation(oxygenprocess)Class:Security1201StudentName:TutorAbstract:withthedevelopmentofscienceandtechnology,theoxygendemandinthegrowing,theoxygenproductionenterpriseproductionscaleisalsoexpanding.Oxygennaturedeterminestheoxygenintheproductionandstorageofcombustionandexplosionofinherentdangerexistsintheprocessandoxygenequipmententerpriseslarge-scale,highlycontinuous,highdegreeofautomation,theproductioncharacteristicsofhighriskdecidedthattheithasalotofpotentialrisk.Therefore,torealizethesafetyevaluationoftheoxygenenterprisesisverynecessary.Inthispaper,throughthesafetyevaluationoftheknowledgeofLueyangsteeloxygenstationsafetyriskassessment,intheproductionprocessofsystemanalysis,toidentifytheexistenceofdangerousandharmfulfactorsandtheoxygenmakingprocessoftheprojectwerefireandexplosionindex,relatedsafetycountermeasuresareputforward.Bycalculatingthefireandexplosionindex,evaluationoftheinherentriskleveloffireandexplosion,thefinalcalculationofthecompensationcoefficientofsafetymeasures,themaximumpossiblepropertylosses,etc..Trytoreducetheoccurrenceofaccidentsofoxygenstation,avoidoxygenstationintheproductionofhumaninjury,reducethelossofproperty.Keywords:safetyevaluation,DOW,oxygenprocess,fireandexplosionindex第3页目录1引言..................................................................................................................51.1项目概况...............................................................................................51.2主要评价内容.......................................................................................61.2.1生产工艺流程简介....................................................................61.2.2主要工艺装置情况....................................................................71.2.3氧气储存设施情况....................................................................81.3主要评价依据.......................................................................................81.3.1法律、法规依据........................................................................81.3.2技术标准、规范........................................................................92.危险、有害因素辨识与分析........................................................................102.1辨识原则.............................................................................................102.2辨识的方法.........................................................................................102.2辨识的结果及分析.............................................................................112.3重大危险源的辨识.............................................................................122.3.1重大危险源的辨识依据..........................................................122.3.2重大危险源的分类..................................................................122.3.3重大危险源的危险性分级......................................................133.评价单元的划分及评价方法的选择............................................................133.1评价单元的划分.................................................................................133.2评价方法的选择.................................................................................134.安全评价过程................................................................................................14第4页4.1评价内容.............................................................................................144.2评价过程.............................................................................................144.3火灾爆炸指数的计算与评价.............................................................154.2.1氧气的物质系数MF..............................................................154.2.2一般工艺危险系数值F1.......................................................154.2.3特殊工艺危险系数值F2.......................................................154.2.4工艺单元危险因素值F3.......................................................164.2.5火灾和爆炸指数F&EI...........................................................164.2.6火灾爆炸固有危险性.............................................................164.2.7安全措施补偿系数计算.........................................................174.2.8最大可能财产损失.................................................................185.提出安全对策措施........................................................................................196.评价结论及建议............................................................................................20参考文献...........................................................................................................21致谢...............................................................................................................22第5页1引言钢铁产业作为我国国民经济的一项重要基础产业,为国家经济快速健康发展做出了无法取代的贡献，而制氧企业的原料、产品包括氧、氮、氩等，均为压缩气体和液化气体，而制氧工艺复杂，生产车间环境多变，诸多不
