炼厂加氢反应器的事故后果定量风险评价(编程)

沈阳航空航天大学毕业设计（论文）I摘要加氢反应器的工作温度和压力都比较高，如果反应器超温、超压或发生泄漏，很有可能发生火灾或爆炸事故，造成严重的事故后果。对加氢反应器进行定量风险评价可以了解其危险后果以及影响范围，有助于企业制定事故应急预案，并事先采取预防措施，以便减少人员伤亡和财产损失。本次毕业设计首先定性分析了加氢反应器中存在的危险、有害因素。基于加氢反应器可能发生的火灾、爆炸事故类型，选择了适宜的模型来定量地评价事故后果，.利用MATLAB软件编制加氢反应器定量风险评价软件。最后，.结合某煤焦油加氢反应器事故案例进行事故后果定量风险评价。关键词：火灾爆炸；事故；蒸气云爆炸；风险评价沈阳航空航天大学毕业设计（论文）IITheQuantitativeRiskAssessmentoftheRefineryHydrogenationReactorAccidentConsequencesAbstractThoughtheworking-temperatureandpressureofhydrogenationreactorisveryhigh，Hydrogenationreactorislikelytobringaboutfireorexplosionaccident，andseriousconsequences.Studyingthequantitativeriskevaluationonthehydrogenationreactorcanhelpusunderstanditsdangerousconsequencesandinfluencescope，enterpriseformulateaccidentemergencyplan，takepreventivemeasuresinadvance，andreducecasualtiesandpropertylosses.Firstly，thisgraduationdesignanalysesthedangerousandharmfulfactorsexistinginthehydrogenationreactor.Basedonthepossibilityoffireandexplosionaccidenttypesofthehydrogenationreactor，thesuitablemodelischoosedtoquantitativelyevaluatetheaccidentconsequences.Then，theMATLABsoftwareisusedtoevaluatetheaccidentalconsequencesofhydrogenationreactor.Intheend，acoaltarhydrogenationreactoraccidentcaseisusedtoquantitativelycalculatetheconsequencesoftheaccident.Keywords:Fireexplosion;Accident;Vaporcloudexplosion;Riskassessment沈阳航空航天大学毕业设计（论文）III目录1绪论.............................................................................................................................11.1引言...................................................................................................................11.2国内外研究现状...............................................................................................11.2.1国外研究现状与发展.............................................................................11.2.2国内探究现状与发展.............................................................................21.3本文研究内容及意义.......................................................................................22加氢技术及有害因素分析........................................................................................32.1加氢技术工艺...................................................................................................32.2原料危险与有害因素分析..............................................................................42.2.1火灾、爆炸危险物质.............................................................................42.2.2中毒危险物质.........................................................................................42.3工艺过程危险与有害因素分析.......................................................................62.3.1火灾爆炸危险性.....................................................................................62.3.2灼烫危险性分析....................................................................................72.4其他危险、有害因素分析...............................................................................82.4.1触电.........................................................................................................82.4.2高处坠落.................................................................................................82.4.3粉尘.........................................................................................................82.4.4物体打击.................................................................................................83定性、定量风险评价方法........................................................................................93.1加氢反应器的定性风险分析..........................................................................93.1.1事件树分析.............................................................................................93.1.2泄露概率...............................................................................................103.2氢气泄漏定量风险评价模型........................................................................113.2.1喷射火...................................................................................................113.2.2泄漏扩散...............................................................................................143.2.3火球.......................................................................................................153.2.4蒸气云爆炸...........................................................................................173.3油品泄漏定量风险评价模型........................................................................203.3.1喷射火...................................................................................................203.3.2火球.......................................................................................................213.3.3蒸气云爆炸...........................................................................................214MATLAB软件评价反应器风险..........................................................................234.1软件开发工具................................................................................................23沈阳航空航天大学毕业设计（论文）IV4.1.1MATLAB软件介绍.............................................................................234.1.2GUI开发界面..............................................................
