Effect of liquid properties on the agglomerating tendency of a wet gas–solid fluidized bed

In many industrial processes, a liquid is spayed right into a fluidized bed. The liquid may then dry, as in fluidized bed dryers and agglomerators, evaporate, as in gas-phase polymerization reactors, or react, as in fluid cokers or catalytic crackers. id injected in a fluidized bed may spread on the bed particles, increasing their cohesivity and reducing the bed fluidity. The liquid may also result in the formation of wet agglomerates that settle at the bottom of the bed. In fluid cokers, it is crucial to prevent agglomeration of wet particles. According to the literature, the liquid viscosity, surface tension and wettability affect the formation of agglomerates. jective of this work was to determine which liquid properties affect the bed fluidity and the formation of agglomerates.
