论文标题氯化苄制苯甲醇工艺过程模拟及优化摘要作为重要的有机中间体的苯甲醇,广泛应用于纺织助剂、感光材料、医药、香料、和涂料工业。合成苯甲醇的方法很多，本论文选择了高收率、无环境污染的氯化苄连续水解法，查看相关文献，设计了连续水解法制备苯甲醇的工艺流程，该工艺流程包括苯甲醇生成、氯化苄回收和苯甲醇精馏，利用AspenPlus模拟苯甲醇生产过程并对其进行优化。经过优化后，苯甲醇的纯度增大到99.98%，三个精馏塔塔板数减少了9.3%，冷凝器能耗减少1.25%，再沸器能耗增大了2.14%，苯甲醇成品塔的操作费用减少了，有效地降低了工艺的成本。关键词：氯化苄连续水解苯甲醇AspenPlus模拟优化AbstractAsanimportantorganicintermediate,benzylalcoholiswidelyusedintextileauxiliaries,论文标题photosensitivematerials,medicine,perfumeandcoatingindustries.Synthesisofbenzylalcoholalot,thispaperchosethehighyield,nopollutionoftheenvironmentofcontinuoushydrolysisofbenzylchloridemethod,tochecktherelatedliterature,thedesignofthecontinuoushydrolysisprocessofpreparationofbenzylalcohol,thetechnologicalprocessincludingtheproductionofbenzylalcohol,benzylchloriderecycle,andbenzylalcoholdistillation,usingAspenPlussimulationbenzenemethanolproductionprocessanditsoptimization.Afteroptimization,thepurityofbenzylalcoholwasincreasedto99.98%,thenumberofplatesinthreedistillationtowerswasreducedby9.3%,theenergyconsumptionofcondenserwasreducedby1.25%,andtheenergyconsumptionofreboilerwasincreasedby2.14%.Keywords:benzylalcoholAspenplussimulationoptimization.目录摘要.........................................................................................................................................I论文标题Abstract.....................................................................................................................................II第1章绪论.............................................................................................................................11.1引言....................................................................................................................................11.2研究背景............................................................................................................................11.3苯甲醇的合成方法.............................................................................................................11.3.1氯化苄水解法.................................................................................................................11.3.2国外生产苯甲醇的工艺.................................................................................................21.4化工工程模拟及方法.........................................................................................................31.5选题的意义及研究内容.....................................................................................................41.5.1选题的意义.....................................................................................................................41.5.2研究内容.........................................................................................................................4第2章连续水解法生产工艺流程设计..................................................................................42.1生产工艺流程的设计.........................................................................................................42.2工艺参数及控制指标........................................................
