Effect of liquid properties on the agglo

In many industrial processes, a liquid is sprayed into a fluidized bed where it can dry, evaporate, or react with the solids present. This study investigates the influence of liquid properties—specifically viscosity, surface tension, and wettability—on the fluidity of the bed and the formation of wet agglomerates. A literature review indicates that these properties significantly affect agglomeration behavior, which is crucial in processes such as fluid cokers where excessive agglomeration can hinder performance. The methodology included a series of experiments using pure liquids injected into the fluidized bed to assess changes in bed fluidity and agglomerate formation. The results demonstrated that certain liquid characteristics notably enhance the cohesiveness of the particles while reducing overall fluidity. Thus, identifying and controlling these properties can serve as a critical factor in optimizing industrial operations involving fluidized beds. The findings underscore the need for careful consideration of liquid properties when designing and operating fluidized bed systems. D 2004 Elsevier B.V. All rights reserved.
