乙酸乙酯的反应器设计流程

摘要乙酸乙酯是一类重要的有机溶剂和有机化工基本原料，其用途非常广泛，目前我国采用传统的方法制备即乙酸和乙醇为原料，浓硫酸为催化剂直接催化合成乙酸乙酯。所以通过对乙酸乙酯的理化性质，社会用途与需求和国内外发展现状进行研究调查以及乙酸乙酯在实验室制法和工业生产各方面对比之后，为此对乙醇和乙酸的缩合进行了乙酸乙酯合成工艺的课程设计。本选题为年产量为年产5017吨乙酸乙酯的反应器的设计。对工业生产中的物料衡算，热量衡算和合成工艺的设备等方面为间歇釜式反应器的工业设计提供较为详尽的数据与图纸。本选题为年产量为年产5017吨乙酸乙酯的反应器的设计。关键字：乙酸；乙醇；乙酸乙酯；合成工艺；间歇式反应器AbstractEthylacetateisakindofimportantorganicsolventsandbasicorganicchemicalrawmaterials,itsapplicationisverybroad,ourcountrypreparedusingtraditionalmethodsthataceticacidandethanolasrawmaterial,concentratedsulfuricacidcatalyzeddirectsynthesisofethylacetate.Sothroughthesocialuseofphysicalandchemicalpropertiesofethylstatusquoneeds,andconductresearchanddevelopmentathomeandabroadaswellasvariousaspectsofethylacetateaftercomparinglaboratoryandindustrialproductionsystemoflaw,forthecondensationofethanolandaceticacidweresynthesisofethylcurriculumdesign.Thetopicfortheannualproductionof5,017tonsannualoutputofethylreactordesign.Inindustrialproductionofmaterialbalance,heatbalanceandsynthesisprocessequipmenttoprovidemoredetaileddataanddrawingsforthebatchtankreactorindustrialdesign.Thetopicfortheannualproductionof5,017tonsannualoutputofethylreactordesign.Keywords:Aceticacid;Ethanol;Ethylacetate;Synthesisprocess;Batchreactor目录摘要..............................................................................ⅠAbstract..............................................................................Ⅱ第一章前言......................................................................551.1乙酸乙酯概述..................................................................551.1.1乙酸乙酯的简介..........................................................551.1.2乙酸乙酯的用途..........................................................551.1乙酸乙酯的产能和市场需求....................................................661.2.1世界乙酸乙酯的产能与消费情况............................................661.2.2我国乙酸乙酯的产能与消费状况............................................66第二章工艺流程的比较................................................................882.1本课题设计内容和要求..........................................................882.1.1设计要求................................................................882.1.2具体设计内容............................................................882.2设计方案的确定................................................................992.2.1反应原理................................................................99第三章工艺设计方案............................................................10103.1原料路线确定的原则和依据....................................................10103.1.1乙醇乙酸酯化法........................................................10103.1.2乙醛缩合法............................................................11113.1.3乙烯加成法............................................................11113.1.4乙醇脱氢法............................................................1111第四章工艺设计计算................................................................13134.1设计依据....................................................................13134.2设计方案....................................................................13134.3设计条件....................................................................13134.4反应条件....................................................................13134.5工艺计算及方案选择..........................................................13134.5.1反应器的的操作有间歇操作和连续操作....................................13134.5.2间歇反应釜进料........................................................14144.5.3流量的计算............................................................14144.5.4反应体积及反应时间计算................................................15154.6连续性反应釜进料的计算......................................................16164.6.1流量的计算............................................................16164.6.2反应体积及反应时间计算................................................17174.6.3设备和工艺流程图......................................................1818第五章热量衡算....................................................................19195.1热量衡算总式....................................................................19195.2每摩尔各种物值在不同条件下的值.........................................20mpC,205.3各种气象物质的参数如下表....................................................20205.4每摩尔物质在80℃下的焓值....................................................21215.5总能量衡算..................................................................21215.6换热设计...................................................................22225.7水蒸气的用量...............................................................2222第六章设备设计与选型..............................................................23236.1反应釜体及夹套的设计计算....................................................23236.1.1筒体和封头的几何参数的确定............................................23236.1.2筒体和封头的型式......................................................23236.1.3筒体和封头的直径......................................................24246.1.4确定筒体高度H........................................................24246.1.5夹套直径、高度的确定..................................................24246.2釜体及夹套厚度的计算........................................................24246.2.1设备材料....................
