3万吨丁苯橡胶毕业设计

化工与材料工程学院毕业设计-I-摘要本设计为年产3万吨乳液聚合丁苯橡胶装置工艺设计，以聚合工段为设计的主要对象。丁二烯和苯乙烯为主要聚合单体，松香酸钾皂、硫酸亚铁、叔十二碳硫醇、过氧化氢对锰烷等为助剂，采用低温乳液聚合法连续生产工艺合成丁苯橡胶。丁苯橡胶具有优异的物理性能和良好的加工性能，在工业生产和日常生活中应用广泛。本设计在掌握丁苯橡胶合成原理、聚合方法、工艺流程以及国内外的发展现状的基础上，进行了聚合工段的物料衡算、热量衡算、主要设备选型计算及简单的技术经济分析，以及绘制带控制点的工艺流程图、设备布置图、管道布置图，编写了设计说明书和设计计算书。关键词：丁苯橡胶；乳液聚合；工艺设计；丁二烯；苯乙烯年产3万吨丁苯橡胶装置聚合工段工艺设计-II-AbstractThisdesignfortheannualoutputof30000tonsofemulsionpolymerizationofstyrenebutadienerubberplantprocessdesignbasedonpolymerizationsectiondesignofthemainobject.Butadieneandstyreneasthemainmonomer,rosinpotassiumsoap,ferroussulfate,uncletwelvecarbonmercaptanandhydrogenperoxideasadditivesonmanganesealkanes,etc,thecontinuousproductionprocessusingemulsionpolymerizationatlowtemperaturesynthesisofstyrene-butadienerubber.Styrenebutadienerubberhasexcellentphysicalpropertiesandgoodprocessability,hasbeenwidelyappliedinindustrialproductionanddailylife.Thisdesigninmasteryofstyrene-butadienerubbersynthesisprinciple,polymerizationmethod,technologicalprocessandthedevelopmentsituationathomeandabroad,onthebasisoftheaggregationprocessofmaterialbalance,heatbalanceandmajorequipmentselectioncalculationandsimpletechnicalandeconomicanalysis,anddrawthecontrolpointsofprocessflowdiagram,equipmentlayout,pipinglayout,writingthedesignspecificationanddesigncalculation.KeyWords：Butadiene-styrenerubber；Emulsionpolymerization；Processdesign；Butadiene；Styrene化工与材料工程学院毕业设计-I-目录摘要...............................................................IAbstract..............................................................II第一篇设计说明书.....................................................12.绪论...............................................................22.1.设计依据、指导思想.............................................22.1.1.设计依据..................................................22.1.2.指导思想..................................................22.2.设计地区的自然条件.............................错误!未定义书签。2.3.厂址的选择.....................................错误!未定义书签。2.4.产品方案及生产规模.............................................22.5.车间布置与岗位人员配制.........................................22.6.节能与环境保护.................................................22.6.1.节能......................................................22.6.2.环境保护..................................................32.7.安全生产.......................................................32.7.1.安全特点..................................................32.7.2.消防设施..................................................32.7.3.灭火程序..................................................33.工艺论证.............................................................43.1.工艺原理.......................................................43.2.生产方法论证...................................................44.工艺设计.............................................................64.1.工厂的分配和布置...............................................64.2.工艺流程简图...................................................64.3.橡胶聚合车间工艺流程叙述.......................................64.3.1.本岗位管理范围............................................74.3.2.本岗位操作任务............................................74.4.生产原理及工艺流程.............................................84.4.1.生产原理..................................................84.4.2.工艺流程..................................................84.4.2.1..单体及化学品溶液接收...............................84.4.2.2.聚合................................................94.5.原料产品规格及公用工程条件.....................................94.5.1.原料的技术条件............................................94.5.2.公用工程条件.............................................104.6.工艺过程主要控制指标..........................................114.6.1.丁二烯（BD）净化.........................................114.6.2.聚合.....................................................114.6.2.1.集合进料流量控制精度...............................114.6.2.2.进料流量校正时间间隔...............................114.6.2.3.聚合温度...........................................12年产3万吨丁苯橡胶装置聚合工段工艺设计-II-4.6.2.4.聚合压力...........................................124.6.2.5.转化率.............................................124.6.2.6.门尼粘度...........................................124.6.2.7.反应停留时间.......................................124.6.2.8.结合苯乙烯的量.....................................13第二篇设计计算书....................................................14第1章基础数据....................................................151.1已知基础数据：.................................................151.2计算原则.......................................................16第2章物料衡算.......................................................182.1进料计算.......................................................182.1.1.混合丁二烯和苯乙烯进料...................................182.1.2.新鲜丁二烯和苯乙烯进料...................................182.1.3.辅助物料计算.............................................192.1.4.聚合工段进料表...........................................202.2聚合工段出料计算...............................................21第3章聚合工段热量衡算...............................................223.1聚合热.........................................................223.2冷却显热.......................................................
