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TheQuantitativeRiskAssessmentoftheRefineryHydrogenationReactorAccidentConsequencesAbstractThoughtheworking-temperatureandpressureofhydrogenationreactorisveryhigh，Hydrogenationreactorislikelytobringaboutfireorexplosionaccident，andseriousconsequences.Studyingthequantitativeriskevaluationonthehydrogenationreactorcanhelpusunderstanditsdangerousconsequencesandinfluencescope，enterpriseformulateaccidentemergencyplan，takepreventivemeasuresinadvance，andreducecasualtiesandpropertylosses.Firstly，thisgraduationdesignanalysesthedangerousandharmfulfactorsexistinginthehydrogenationreactor.Basedonthepossibilityoffireandexplosionaccidenttypesofthehydrogenationreactor，thesuitablemodelischoosedtoquantitativelyevaluatetheaccidentconsequences.Then，theMATLABsoftwareisusedtoevaluatetheaccidentalconsequencesofhydrogenationreactor.Intheend，acoaltarhydrogenationreactoraccidentcaseisusedtoquantitativelycalculatetheconsequencesoftheaccident.Keywords:Fireexplosion;Accident;Vaporcloudexplosion;Riskassessment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............
