-年产30万吨环氧乙烷生产车间工艺设计论文——学位论文

哈尔滨理工大学学士学位论文-I-年产30万吨环氧乙烷生产车间工艺设计摘要环氧乙烷（EO）是有机化工中最简单的环醚，属于杂环类化合物，是重要的石化产品。环氧乙烷在低温下为无色透明液体，常温下为无色带有醚刺激性臭味的气体。是以乙烯为原料的主要石油化工产品之一，是乙烯衍生物中仅次于聚乙烯第二位重要产品。是用量比较大的石油化工原料和精细化工产品的中间体，主要用于生产乙二醇及其他二醇类产品。本设计是对年产30万吨环氧乙烷生产车间工艺设计，生产工艺采用的是目前技术比较成熟的、安全可靠的乙烯在高纯氧气中直接氧化制备环氧乙烷（EO）的。依据理论知识和实际生产理论基础制定工艺流程设计生产方案。本设计确定了年产30万吨环氧乙烷EO的生产流程，整个设计包含工艺流程设计与设备、物料衡算、能量衡算。物料衡算和能量衡算以现有物数据为基础进行衡算。其他内容包含设备的选型和设计，绘制工艺流程图、设备装配图、车间布置图、管道平面布置图。本次设计可以为本产品的工艺设计提供技术支持。关键词环氧乙烷；乙烯；工艺设计；设备计算及选型哈尔滨理工大学学士学位论文-II-TheProcessDesignofProducingDepartmentthatProduces300ThousandTonsEthyleneOxideAbstractEthyleneoxideisthesimplestcyclicetherinorganicchemicalindustry.itbelongstoheterocyliccompoundsanditisaveryimportantpetrochemical.ethyleneoxideisacolorlesstransparentliquidatlowtemperaureandatroomtemperature,itiscolorlesswithetherirritatingodorgas,itisoneofthemainpetrochemicalindustryproductswhoserawmateralisethylenceandthesecondimpotantproductinethylenedeivativesafterpolythene.ethyleneoxideistheintermeditadebetweenpetrochimecialmaterial(whooseuselevelisverylarge)andfinechemicalproducts.itismainalyusedinproducesethanediolandotherglyoclgoods.Thisengineeringdesignfocusontheproductingdepartmentthatproduces300thousandtonsannually,thetechnologyinproductionengineeringisrelativelyadvancedandsafe.inhighpurityoxygen,ethyleneoxideizeddirectlytoprepareethyleneoxide.weshouldbasedonthespeculativekoowledgeandtheoreticalbasisofpracticalproductiontoformulateengineeringflowandprojectproductiondesign.Thisengineeringdesigndeterminestheproductionflowofethyleneoxideisannuallyoutputof300thousandtons.thewholeprojectincludingprocessdesignandequipment,materialbalenced、energybalanced.themateralandenergybalancebasedontheexistingdata.othercontentincloudingequipmentselectionanddesignthedrawingofprocessflowsheet,equipmentassembly.designandpipinglayout.thisprogectcanprovidetechnicalsupportforthisproductsprocessdesign.Keywordsoxide,ethylene,processdesign,equipmentcalculationandselection哈尔滨理工大学学士学位论文-III-目录摘要......................................................................................................................IAbstract...............................................................................................................II第1章绪论........................................................................................................11.1课题背景...................................................................................................11.1.1产品意义及用途................................................................................11.1.2国内外工艺技术现状分析................................................................11.1.3生产技术进展....................................................................................21.2环氧乙烷的应用.......................................................................................31.2.1环氧乙烷直接应用............................................................................31.2.2作为有机合成原料............................................................................31.2.3在高新电子行业的应用....................................................................31.3设计目的及内容.......................................................................................41.3.1设计目的............................................................................................41.3.2设计内容............................................................................................4第2章工艺方案的确定....................................................................................52.1工艺方案介绍...........................................................................................52.1.1直接氧化法........................................................................................52.1.2氯醇法................................................................................................52.2设计工艺确定...........................................................................................52.3反应原理...................................................................................................62.3.1氧化反应原理....................................................................................62.3.2二氧化碳吸收、脱除机理................................................................82.4工艺流程...................................................................................................82.4.1工艺流程简介....................................................................................92.5本章小结.................................................................................................11第3章物料衡算..............................................................................................123.1物料衡算.................................................................................................123.1.1物料衡算依据及原理......................................................................123.2反应部分基础计算.................................................................................133.2.1原料气与氧化气组成计算..............................................................143.3吸收塔物料衡算....................................................................................
