聚乙烯流化床表观流化气速研究

The Study of Gas Velocity on Polyethylene Fluidized Bed

通过对线性低密度聚乙烯装置流化床反应器极限流化气速的计算分析,确定了在干气状态和冷凝状态下表观气速的控制范围,并分析了表观流化气速对流化床反应器控制的影响。

Based on the calculation and analysis of the limiting gas velocity for fluidized bed reactor, the range of su- perficial gas velocity in the state of dry gas and condensation was determined. Furthermore, the impact of gas velocity to the control of fluidized bed reactor was analyzed.
