摘要
静电累积会造成反应器结片、结块,影响聚丙烯生产装置正常运行。分析了气相流化床聚丙烯反应器静电形成的原因,采取原料提纯、减小反应器回收液相丙烯用量、增大冷凝量、改换催化剂类型、去除反应器内杂质、合理应用抗静电系统等措施,减弱了反应器内的静电或抑制了静电的生成,保证了聚丙烯装置平稳长周期运行。
Abstract
Accumulation of static electricity in reactor may cause sheeting or chunk,which will affect the stable operation of polypropylene plant.The causes of static electricity formation in gas-phase polypropylene fluidized bed reactor are analyzed.A series of solutions are hence taken,such as purifying raw materials,reducing the flow rate of recycled propylene liquid to reactor,increasing the condensing level,changing different catalysts,removing impurities in reactor,and adding electrostatic resistance system.These solutions reduce static electricity in reactor or restrain the formation of static electricity,which secures the smooth and long period operation of polypropylene plant.
