年产1500吨工业苊的工艺设计

本科毕业设计题目：年产1500吨工业苊工艺设计专题：苊结晶过程的控制专业：应用化学班级：应化BG101姓名：杨军学号：09指导教师：李靖论文共62页，其中：专题4页，译文7页第I页年产1500吨工业苊的工艺设计中文摘要本次设计主要进行年产1500吨工业苊车间的设计。采用双炉双塔生产过程具有连续性比较强，稳定性好、产率高等特点。全文共六章，分章阐述了苊塔的工艺部分与非工艺部分。并对物料，塔的尺寸等进行详细的计算。首先对设计所选工艺的研究背景、目的、意义进行简单阐述,然后对工艺部分进行着重讨论和计算，这一部分先简单介绍原料和产品，进行生产方式的选择，工艺流程的简单介绍,和装置的特点。着重进行计算，其中包括物料衡算、热量衡算和工艺尺寸的计算。计算部分对初馏塔的物料及热量进行了衡算，还计算了最小回流比、最小理论板数、理论板数及实际板数、加料板位置的确定等等。在浮阀塔工艺尺寸计算方面我做了大量的计算，包括浮阀塔的汽液相负荷、塔径计算、塔高的计算等。除苊塔外并根据苊塔要求对冷凝器进行了选型及计算。最后对非工艺部分进行阐述。关键词：苊,工艺,结晶第II页AbstractThedesignismainlycarried1500tonsofindustrialacenaphtheneworkshopdesign.Doubleoventwinproductionprocesscontinuityandstrong,goodstability,highyieldandothercharacteristics.Thisdissertationconsistsofsixchapters,expoundsthecraftpartandNon-craftpartrespectively.Andcalculatethematerial,sizeoftowerdetailedly.First,expoundingbackground,purpose,significanceoftheselectedprocess.thenfocusingonthecraftparttodiscussandcalculate.Thefirstpartofthebriefintroductionofrawmaterialsandproducts,choiceofproduction,asimpleprocess,andthedevicefeatures.Stressecalculating,includingthematerialbalance,energybalanceandsizeofthecalculation.IfeaturesomeofAcenaphthenetowerofmaterialsandenergyforthebalance,calculatetheminimumreturnratio,theminimumnumberofplatetheory,theoryofplatenumberandtheactualnumberplates,feedinglocationoftheboarddetermined,andsoon.TapfloatvalveintermsofsizeandIdidalotofcalculation,includingthesteamvalvetowerliquidload,thetowerdiameter,theoverflowdevices,valvetraylayout,ahightower。ExcepttheAcenaphthenetowerIhaveDesignthecondenserfortheAcenaphthenetower.Finally,ExpoundstheNon-craftpartfacilitiesKeywords:Acenaphthene，Technology，Crystallization第III页目录1绪论............................................................................................错误!未定义书签。2工业苊生产工艺评述................................................................................................22.1国内制取工业苊工艺路线.....................................................................................22.2国外制取工业苊工艺路线.....................................................................................32.3工艺叙述部分.........................................................................................................42.3.1工艺选择...............................................................................................................42.3.2工艺特点...............................................................................................................52.3.3存在问题...............................................................................................................52.3.4工艺流程...............................................................................................................73工艺计算....................................................................................................................93.1设计依据.................................................................................................................9根据设计题目：年产1500吨工业苊工艺设计题目要求相关规定..........................9苊塔设计的项目建议书................................................................................................93.2设计范围.................................................................................................................93.3设计规模和产品......................................................................................................93.3.1规模.......................................................................................................................................93.3.2产品品种、数量和质量...................................................................................................93.3.3设计任务和设计能力.....................................................................................................103.3.4原料组成............................................................................................................................103.4苊塔计算依据.......................................................................................................113.5物料衡算................................................................................................................123.6塔板层数及回流比的计算...................................................................................133.6.1最小数.................................................................................................................................133.6.2最小回流比........................................................................................................................143.6.3理论板数及实际板数.....................................................................................................153.6.4加料板位置的确定..........................................................................................................153.6.5侧线以上最小回流比.....................................................................................................16第IV页3.6.6侧线以上理论板数及实际板数...................................................................................173.7热平衡计算...........................................................................................................................173.
