摘　　要：通过统计丁二烯装置运行存在的问题,分析产生问题规律,发现丁二烯装置运行问题主要是丁二烯聚合,进一步分析聚合原因主要是氧的影响,温度的影响,丁二烯浓度的影响,杂质的影响:铁锈和水等引发剂的影响,通过采取设备防聚合、工艺防聚合、优化阻聚剂、减少设备死角等生产防聚合措施,丁二烯装置运行从一年一清理到平稳运行4年,取得了较好的经济效益,值得总结推广。By taking statistics of butadiene plant operation problems and analyzing the rules that cause the problems,it is found that the main problem of butadiene plant operation is butadiene polymerization.Polymerization causes are further analyzed and are discovered to be mainly the effects of oxygen,temperature,butadiene concentration,and impurities and the effect of initiators such as rust and water.By adopting anti-polymerization measures for equipment and process,optimization of anti-polymerization agent,reducing dead space of equipment and other production anti-polymerization measures,the butadiene plant has been running steadily for 4 years without being cleaned instead of the previous annual clean-up.This has helped the company to achieve better economic benefits,which is worth summarizing and promoting.
