摘要：乙烯裂解炉管的结焦速率决定了乙烯裂解炉的运行周期,抑制炉管结焦是乙烯生产中的研究重点。介绍了炉管内表面结焦对乙烯生产的不良影响及结焦形成的机理;重点分析了炉管内表面涂层技术(在线涂层技术和离线涂层技术)的研究现状,并对在线涂层技术与离线涂层技术的优缺点进行了分析和比较;展望了炉管内表面涂层技术的发展前景及今后研究的重点。
Operating period of ethylene cracking furnace is determined by rate of coking on inner surface of its tube, so study of how to alleviate coking has become a hot topic for ethylene production. The negative effect of coking on ethylene production and coking mechanism were also introduced. Research progress in anti - coke coating technologies was reviewed, including online coating and offline coating technologies. The advantages and shortcomings of the two were compared. Development trend of anti - coke coating technologies and research targets were stated.
