8000ta丙烯腈工艺设计

兰州交通大学毕业设计1摘要本文介绍了丙烯腈生产基本情况及年产8000吨合成工艺系统流程，介绍了丙烯腈的生产情况，合成基本原理，发展前景及工艺流程的概述和工艺合成的基本方法，并且对设备进行物料，热量衡算和工艺计算。在工业生产条件下，对于丙烯氨氧化法，主反应生成丙烯腈，是一个非均相反应；与此同时，在催化剂表面还发生一系列副反应。丙烯腈生产技术的发展主要是朝2个方向：1装置规模向大型化发展。2新型催化剂的开发及应用通过物料衡算，得到所需原料丙烯、氨、硫酸和原料水的消耗量。通过热量衡算确定所需冷却水的用量和设备出口温度。经计算，均满足需要。初步设计阶段经过设备的工艺计算初定的工艺设备型号，其中：标准设备已选定了型号或标准号。对非标准设备，因未进行设备的施工设计，只能给出大致格，可作为向设备专业提出设计条件的依据。关键词：合成工艺流程发展情况衡算兰州交通大学毕业设计2AbstractThisarticledescribesthebasicsituationofacrylonitrileproductionandsynthesisof8，000tonsannualoutputofsystemflow，introducedacrylonitrileproduction，synthesisofbasicprinciples，developmentprospectsandprocessoverviewandsynthesisofthebasicmethodofprocessandequipmentformaterial，AndprocessheatbalancecalculationAcrylonitrileproductiontechnologymainlytowardstwodirections:adevicetolarge-scaledevelopment.2ThedevelopmentandapplicationofnewcatalystsBymaterialbalance，obtaintherequiredrawmaterialpropylene，ammonia，sulfuricacidandwaterconsumptionofrawmaterials.Heatbalancedeterminedbytherequiredamountofcoolingwateroutlettemperatureandtheequipment.Iscalculated，aretomeettheneed.Thepreliminarydesignstagethroughtheequipment，processequipment，processcalculationaninitiallist，including:standardequipmenthasbeenselectedthemodelorstandardnumber.Onnon-standardequipment，theconstructionofequipmentforthedesignnotonlygivesthegeneralformat，thedeviceACNbeusedasthebasisforprofessionaldesignconditionsproposed.Keywords:synthesisprocessdevelopmentaccounting兰州交通大学毕业设计3目录摘要.....................................................................................................................................................1Abstract..................................................................................................................................................21综述...................................................................................................................................................51.1概述..............................................................................................................................................51.2丙烯腈生产技术的发展概述......................................................................................................51.2.1国外的发展情况....................................................................................................................51.2.2国内的发展情况....................................................................................................................61.3丙烯腈的国内外生产情况..........................................................................................................81.3.1世界........................................................................................................................................81.3.2国内........................................................................................................................................91.4丙烯腈生产工艺研究进展........................................................................................................111.4.1国外......................................................................................................................................121.4.2国内......................................................................................................................................131.5近期丙烯腈及其副产品生产动向............................................................................................161.6发展与展望................................................................................................................................162工艺流程.........................................................................................................................................202.1反应过程分析............................................................................................................................202.2小时生产能力............................................................................................................................202.3物料衡算和热量衡算................................................................................................................202.3.1反应器的物料衡算和热量衡算..........................................................................................202.3.2废热锅炉的热量衡算..........................................................................................................242.3.3空气饱和塔物料衡算和热量衡算......................................................................................252.3.4氨中和塔物料衡算和热量衡算..........................................................................................272.3.5换热器物料衡算和热量衡算..............................................................................................312.3.6空气水饱和塔釜液槽..........................................................................................................342.3.7丙烯蒸发器热量衡算..........................................................................................................362.3.8丙烯过热器量衡算..............................................................................................................36兰州交通大学毕业设计42.3.9氨蒸发器热量衡算........................
