Influence of Discharge System on Stability of Gas Phase Fluidized Bed Polymerization
In commercial fluidized bed processes,it is often necessary to discharge the granular materials generated on-line to maintain normal fluidization and polymerization stability.This paper describes in detail the potential disturbance on the hydrodynamic properties caused by the intermittent discharge of the gas-phase polyethylene fluidized bed,the series effects of the discharge time on the polymerization stability of the industrial fluidized bed,and the main countermeasures.It also includes corresponding calculations and rationalization analysis for one of the measures.
