| 摘 要： | 以工厂实际数据为依据,对乙醇胺主副反应动力学方程进行了考核。在Aspenplus中建立了乙醇胺反应过程模型,对影响主副反应的因素进行了模拟和分析,得出了该反应最佳工艺参数:温度应低于110℃;维持1 MPa压力保证反应物料为液相;氨烷比应适当提高;加料形式为环氧乙烷分批加入;反应时间7 min。该工艺参数下,保证了产品分布和质量,降低了副产物含量,为实际乙醇胺生产工艺优化提供了依据。

| Abstract: | Basing on the data from industrial operation,the kinetic equations of the main and side ethanolamine reactions are verified,and the corresponding reaction model is set up by using Apsen plus software.The factors that affect the main and side reactions are stimulated and analyzed.The optimal reaction conditions are as follow.Reaction temperature is lower than 110 ℃.1MPa pressure is maintained to keep the reaction materials liquid.The mass ratio of amine and alkyl should be raised relevantly.EO is batched to the reactor.Reaction resident time is 7 min.This work provides a more optimal reaction condition for the actual production process. |
