安徽工程大学机电学院毕业设计（论文）I氨基乙酸生产工艺设计摘要氨基乙酸又名甘氨酸，它是结构最简单的α-氨基酸，它的用途非常广泛，主要用于农药、医药、食品、饲料以及制取其它氨基酸，合成表面活性剂等。氨基乙酸的生产方法有很多种，主要有氯乙酸氨解法和施特雷克法。在国内，由于技术、原料等原因，大都采用氯乙酸氨解法。本设计的目的在于对模拟年产1万吨氨基乙酸的厂房工艺进行设计和优化，本设计简要介绍了氨基乙酸的主要用途，国内外的生产情况，研究进展和未来的发展趋势。结合国内的实际情况，本设计选用了氯乙酸氨解法，采用间歇式的生产方式，初步设计要求年产量1万吨，参照了许多文献及数据，对整个生产过程做了物料衡算，主要设备进行了热量衡算，并对主体设备氨化合成釜进行了设计，对生产工艺流程进行了优化，对车间进行了布置和规划。设计经多次修改和调整，得到许多数据和能控制的工艺参数，所得到的产品理论上符合设计要求。关键词：氨基乙酸；生产工艺；收率；氯乙酸氨解王淼氨基乙酸生产工艺设计IIANNUALOUTPUTOFGLYCINEWORKSHOPPROCESSDESIGNABSTEACTGlycineisthemostsimplestructureoftheα-aminoacids,it'suseisveryextensive,mainlyforagriculturalchemicals,pharmaceuticals,food,feedandotherproductionofaminoacids,syntheticsurface-activeagent.Therearemanymethodsofproducinglycine.ThemainsolutionsareammoniaandChloroacetateStrecklaw.Athome,becauseoftechnology,rawmaterialsandotherreasons,mostplantsusechloroaceticacidammonolysisprocess.Thepurposeofthedesignistooptimizetheworkshopprocessofanannualoutputof1,0000tonsofGlycine.Thedesigngivesabriefingontheprocessofthemainpurposesofglycine,thesituationoftheproductionathomeandabroad,theresearchprogressandfuturedevelopmenttrends.WiththeactualsituationdevelopmentinChina,thedesignchosethechloroaceticacidammonolysisprocessandusetheintermittentmodeofproduction.Thepreliminarydesignrequirementsofannual10,000tons,Searchedanumberofdocumentsanddata，didthematerialbalanceoftheentireproductionprocesstheheatbalanceofthemajorequipment,designedthemainequipmentaminationofreactor,optimizedtheproductionprocess.Afterwerepeatedmodificationsandadjustments,wegotmanydataandbeabletogetcontroloftheprocessparameters,whicharetheoreticallyinlinewiththeproductofthedesignrequirements.KEYWORDS：glycine;productionprocess;yield;chloroaceticacidammonolysisprocess安徽工程大学机电学院毕业设计（论文）III目录引言.................................................................1第1章概述.....................................................-2-1.1氨基乙酸的基本性质...............................................-2-1.2产品用途.........................................................-2-1.2.1应用于农业行业.................................................-2-1.2.2应用于医药行业.................................................-3-1.2.3应用于饲料行业.................................................-3-1.2.4应用于食品行业.................................................-3-1.2.5应用于表面活性剂和日化行业.....................................-3-1.2.6其他方面.......................................................-3-1.3市场需求与技术现状...................................................31.4生产厂家..........................................................-4-1.5发展前景.........................................................-4-1.6生产技术的发展趋势...............................................-4-1.7氨基乙酸的生产工艺...............................................-5-1.7.1氯乙酸氨解法...................................................-5-1.7.2施特雷克法(cstercker法).......................................-5-1.7.3氢氰酸法合成氨基乙酸新工艺.........................................51.7.4生物合成法.....................................................-6-1.8本产品所选线路及可行性分析.......................................-6-第2章生产工艺流程及各工艺指标的确定.................................72.1生产基本原理及化学方程式.............................................72.2原料规格及性质.......................................................72.2.1基本原料...........................................................72.2.2原料质量标准.......................................................72.3生产工艺流程叙述及工艺流程方框图.....................................82.4主要工艺指标的确定....................................................92.4.1生产工艺特点.......................................................92.4.2工艺指标的确定.....................................................92.4.3结语..............................................................11第3章工艺计算..................................................-12-3.1物料衡算........................................................-12-3.1.1原料及产品规格....................................................123.1.2衡算记住..........................................................123.1.3已知定量..........................................................123.1.4列衡算式..........................................................123.2热量衡算............................................................173.2.1计算Q1与Q4.......................................................173.3.2过程热效应Q3计算.................................................193.2.3Q2的计算..........................................................20第4章主体设备氨化合成釜设计....................................-21-王淼氨基乙酸生产工艺设计IV4.1体积估算............................................................214.2确定筒体和封头形式..................................................214.3确定筒体和封头直径..................................................214.4确定筒体高度........................................................214.5确定夹套的直径......................................................224.6确定夹套的高度......................................................224.7计算传热面积........................................................224.8计算夹套筒体，封头厚度..............................................224.9计算内筒筒体厚度....................................................224.10搅拌器.........
