合成氨变换工段毕业设计说明书VIP免费

可编辑可修改摘要本文是关于重油为原料年产8万吨氨一氧化碳变换工段初步设计。在合成氨的生产中，一氧化碳变换反应是非常重要的反应。用重油制造的原料气中，含有一部分一氧化碳，这些一氧化碳不能直接做为合成氨的原料，而且对合成氨的催化剂有毒害作用，必须在催化剂的催化作用下通过变换反应加以除去。一氧化碳变换反应既是原料气的净化过程，又是原料气的制造过程。本设计主要包括工艺路线的确定、中温变换炉的物料衡算和热量衡算、触媒用量的计算、中温变换炉工艺计算和设备选型、换热器的物料衡算和热量衡算以及设备选型等。并且综合各方面因素对车间设备布置进行了合理的设计，最终完成了20000字的设计说明书及生产工艺流程图、车间平立面布置图及主体设备装配图的绘制。关键词：重油；一氧化碳变换；中温变换炉；流程图精选模板可编辑可修改AbstractThisarticlewasabouttheannualoutputofheavyoilasrawmaterialstotransformeightthousandtonsofcarbonmonoxideammoniapreliminarydesignsection.Intheproductionofammonia,transformationofcarbonmonoxidewasaveryimportantreaction.Manufacturedusingheavyoilfeedgaswhichcontainapartofcarbonmonoxide,carbonmonoxidecouldnotbedirectlyusedasthoseoftherawmaterialsofsyntheticammonia,butalsoacatalystforammoniapoisoningeffecttheremustbeacatalystfortransformationthroughthecatalyticreactiontoberemoved.Transformationofcarbonmonoxideisagaspurificationprocessofrawmaterials,butalsothemanufacturingprocessoffeedgas.Thedesignofthemainrouteswhichincludetheidentificationprocess,themediumvariantofthefurnacematerialbalance,heatbalance,thecalculationoftheamountofcatalyst,inthevariablefurnaceprocessofcalculationandselectionofequipment,heatexchangerofthematerialbalanceandheatbalanceaswellasequipmentselectiontypeandsoon.Takingallfactorsandworkshopequipmenttocarryoutareasonablearrangementofthedesign.Intheend,the20000-wordstatementandmapproductionprocess,shoppingfacadeandthemainequipmentlayoutdrawingassemblywerecompleted.Keywords:Heavyoil;Transformationofcarbonmonoxide;Temperatureshiftconverter;Flowchart精选模板可编辑可修改精选模板可编辑可修改目录摘要.....................................................................................................................................ⅠAbstract....................................................................................................................................Ⅱ第1章总论.............................................................................................................................11.1概述..............................................................................................................................11.1.1一氧化碳变换反应的意义与作用.......................................................................11.1.2国内外研究现状...................................................................................................11.2设计依据......................................................................................................................11.3厂址的选择..................................................................................................................21.3.1厂址选则...............................................................................................................21.3.2方案比较...............................................................................................................21.4设计规模与生产制度..................................................................................................31.4....
