煤气初冷及硫酸铵生产工艺设计VIP免费

河南城建学院本科毕业设计（论文）第1页设计说明本设计对焦炉煤气的处理采用半负压操作系统，煤气的初冷采用的是横管式间接初冷器。首先，概述了煤气初步冷却的目的意义，介绍了鼓风冷凝工段的工艺流程，常用的初冷工艺及工艺流程中的常用设备，并对鼓冷工段进行了物料衡算和热量衡算。通过热量衡算和物料衡算确定了设备的选型。其次，采用喷淋式饱和器生产硫酸铵的工艺，并以饱和器母液生产粗轻吡啶最后，对脱硫和苯回收工艺作说明。同时也对介绍了用硫酸法吸收氨制取硫酸铵的工艺，并对硫酸吸收氨的工艺原理及注意事项做了一些说明，以及对硫酸铵生产工艺的物料衡算和热量衡算，硫酸铵生产的主设备及辅助设备的设计计算。回收轻吡啶的中和器的物料衡算也进行了相应的设计。关键词：横管式初冷器物料衡算硫酸铵饱和器河南城建学院本科毕业设计（论文）第2页DesigndescriptionInthisdesign,thecokeovengastreatmentusingavacuumoperatingsystem,thegasprimarycoolingisusedinhorizontalpipetypeindirectcoolingdevice.First,anoverviewofthegasprimarycoolingpurposeandmeaning,introducedtheblastcondensationprocessflow,commonlyusedprimarycoolingprocessandprocessusedintheequipment,andthedrumcoolingsectionforthematerialbalanceandheatbalance.Byheatbalanceandmaterialbalancecalculationtodeterminetheselectionofequipment.Secondly,usingthespraytypesaturatorforammoniumsulfateproductionprocess,andtothesaturatorliquorproductionoflightpyridine.Finally,onthedesulfurizationandbenzenerecoveryprocessfor.Atthesametimealsointroducedbysulfuricacidmethodforpreparingammoniumsulfateofammoniaabsorptionprocess,andthesulfuricacidtoabsorbammoniaprocessprincipleandmattersneedingattentionaredescribed,aswellasforammoniumsulfateproductionprocessofthematerialbalanceandheatbalance,ammoniumsulfateproductionofmainequipmentandauxiliaryequipmentdesign.Recoveryofpyridineneutralizermaterialbalancehasalsomadethecorrespondingdesign.Keywords:crosstubeprimarycoolingdeviceformaterialbalancecalculationforammoniumsulfateSaturator河南城建学院本科毕业设计（论文）第3页目录设计说明.............................................................1引言.................................................................51焦炉煤气初冷工艺...................................................71.1煤气的间接冷却工艺............................................71.2初冷器冷却....................................................81.2.1间接初冷法..............................................81.3煤气的直接冷却工艺...........................................112初冷工艺的计算....................................................132.1集气管的物料平衡和热计算.....................................132.1.1物料平衡...............................................132.1.2集气管的热计算..........................................152.2横管初冷器热量和物料衡算.....................................173硫酸铵制取工艺....................................................214硫酸铵工艺计算....................................................254.1物料衡算.....................................................254.1.1氨平衡及硫酸用量的计算..................................264.1.2水平衡及母液温度的确定..................................274.2热平衡及煤气预热器出口温度的计算.............................295硫酸铵生产的主设备的计算..........................................356硫酸铵附属设备的计算..............................................386.1除酸器的计算和选型...........................................386.2离心机的计算和选型..........................................
