摘要
苯乙烯在化工生产中非常重要,它能够生产出聚苯乙烯、丁苯橡胶等合成的高分子材料,应用的领域也非常广泛,例如在纺织、涂料、医疗等领域。大多数工业生产都是使用乙苯脱氢制苯乙烯工艺,苯乙烯在常温状冴下会发生聚合反应,这种情冴不利于生产的顺利迚行,所以需要对工作过程中产生的苯乙烯聚合问题迚行研究和分析。提出设计加入阻聚剂系统、提高操作水平、更新填料等有针对性的预防和解决办法,保证整个石化企业的安全稳定生产。
Styrene is very important in chemical production.It can be used to produce synthetic polymer materials,such as polystyrene and styrene-butadiene rubber.Its application field is also very wide,for example the fields of textiles,coatings,medical and so on.Most of the production in the industry uses the ethylbenzene dehydrogenation to styrene process.Styrene easy polymerizes at normal temperature,which is not conducive to the smooth progress of production.Therefore,it is necessary to study and analyze the styrene polymerization problems generated during the work process.In this paper,prevention measures and solutions were proposed,such as adding a polymerization inhibitor system,improving the operation level and updating the filler,so as to ensure safe and stable production of the petrochemical enterprise.
