【摘要】 为深入了解环氧乙烷水合管式反应器的操作与性能,采用交错网格上的SIMPLE算法,选择4种典型的反应动力学模型对环氧乙烷非催化水合制乙二醇反应器进行了数值模拟,并与文献数据进行了比较,确定了适宜于水合反应器模拟的动力学模型。利用该模型模拟得到了反应器在流动充分发展后的截面温度和转化率分布,考察了入口温度及水合比等工艺条件对产品分布的影响。更多还原

【Abstract】 In order to understand the operation and performance of the ethylene oxide tubular reactor,the SIMPLE algorithm with variables arranging on a staggered grid was employed for numerical simulation of non-catalytic hydration reactor of ethylene oxide for glycol production.Four typical kinetic models were chosen to implement the simulation and results obtained were compared with the data from literature,then the most suitable kinetic model was determined for the reactor design.Further,fully developed temperature and conversion rate profiles on the cross-section of the reactor were obtained with this model and impacts of the inlet temperature and water/EtO ratio on product distribution was also investigated.更多还原
