年产4万吨丁苯橡胶的工艺设计VIP免费

工学学士学位毕业设计课题名称：年产4万吨丁苯橡胶生产工艺设计2012年06月01日摘要本设计是以丁二烯和苯乙烯为原料，年产4万吨丁苯橡胶的工艺设计。通过比较目前丁苯橡胶的聚合生产方法，最后确定以低温乳液聚合法作为聚合的工艺生产方法。在设计过程中，根据设计任务书的要求，进行了较为详细的物料恒算和能量恒算，对设备进行了工艺计算和选型，同时对聚丁苯橡胶生产过程中的安全注意事项及“三废”治理作了相关说明。综合上述工艺计算和设计结果，绘制出了工艺流程图、主要设备图以及厂区布置图。关键词:丁苯橡胶乳液聚合工艺设计丁二烯苯乙烯AbstractThedesignisbasedonbutadieneandstyreneasrawmaterials,withanannualoutputof40000tonsofSBRprocessdesign.BycomparingwiththepresentSBRpolymerizationproductionmethod,wemakeadecisiontotreatemulsionpolymerizationatlowtemperatureaspolymerizationproductionmethodatlast.Inthedesignprocess,inaccordancewiththerequirementsofthemissiondesign,amoredetailedmaterialbalanceandenergybalance,equipmentforthecalculationandselectionprocess,atthesametimeonstyrenebutadienerubberproductionintheprocessofattentiontosafetyissuesandthe"threewastes"managementshouldbemadeanote.Drawingtheprocessflowdiagram,themainequipmentandplantlayoutaccordingtotheprocessdesignandcalculationresults,.Keywords:SBR,Emulsionpolymerization,Processdesign,butadiene,styrenemonomer目录摘要......................................................................................................................I第1篇设计说明书..................................................................................................1第1章绪论..........................................................................................................11.1丁苯橡胶的市场分析.....................................................................................11.1.1国外生产情况......................................................................................11.1.2国内生产情况......................................................................................21.2丁苯橡胶合成技术进展.................................................................................41.2.1乳聚丁苯橡胶的合成技术进展..........................................................41.2.2溶聚丁苯橡胶合成技术进展..............................................................51.2.3我国丁苯橡胶新技术的开发..............................................................61.3设计依据、指导思想...................................................................................61.3.1设计依据.............................................................................................61.3.2指导思想.............................................................................................61.4设计地区的自然条件...................................................................................7第2章工艺论证......................................................................................................82.1产品的结构与性能........................................................................................82.1.1名称及其结构......................................................................................82.1.2丁苯橡胶的性能...................................................................................82.1.3丁苯橡胶的用途...................................................................................92.2工艺原理..................................................................
