丁二烯抽提装置防聚合措施的应用分析

Application of polymerization prevention measures in Butadiene Extraction Plant

分析了某丁二烯抽提装置丁二烯的聚合原理,指出控制氧的进入和减少设备死角是防止聚合发生的主要方法;对比讨论了NMP和DMF法在防聚合方面的应用情况,并提出了完善措施。

The article analyzed the butadiene polymerization mechanism of butadiene extraction plant and pointed out that the control of oxygen in system and reduction of dead area in equipment is the main method to prevent polymerization 。Comparison and discussion were made to the application situation of NMP and DMF processes in polymerization prevention and perfection measures were put forward。
