摘　　要：针对气相法线型低密度聚乙烯(LLDPE)装置的生产特点,分析指出生产负荷波动的主要原因有:催化剂、原料组分、反应温度控制参数以及与反应相关的其他系统设备故障的影响。并提出相应措施:控制催化剂活性、控制催化剂的加入量、优化反应温度的控制参数。从而确保了气相法LLDPE装置的平稳运行。In accordance with the characters of vapor phase linear low density polyethylene （LLDPE） plant, this paper pointed out the main reasons for load fluctuation, involving catalyst, composition of raw materials, control parameter of reaction temperature and the failures of other facilities related to the reaction. The countermeasures put forward for dealing with the problem included controlling activity of the catalyst, controlling dosage of the catalyst, optimizing the control parameter of reaction temperature. The adoption of the measures ensured the steady operation of the LLDPE olant.
