摘要
某石化公司低密聚乙烯车间采用UNIVATION公司UNIPOL气相流化床聚乙烯生产工艺,年设计生产能力45万t,是国内单套生产能力较大的装置之一。列举了装置开工至今气相流化床反应器生产过程遇到的一些实际问题,提出处理措施。总结了一些与反应器操作相兲过程优化调整的方法和经验,为同类型装置生产提供借鉴和参考。
A petrochemical company’s low-density polyethylene unit adopts UNIVATION’s UNIPOL gas-phase fluidized bed polyethylene production process, with an annual designed production capacity of 450 000 tons. In this paper, some practical problems in the production process of gas phase fluidized bed reactors were listed, and treatment measures were proposed. Some methods and experiences of process optimization and adjustment related to reactor operation were summarized, which could provide some reference for the production of same type of equipments.
