Hydrodynamic Behavior of Particles in a Jet Flow of a Gas Fluidized Bed

Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from  macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...

Analysis of Changes on Mean Particle Size in a Fluidized Bed using Vibration Signature

Vibration signals were measured in a lab-scale fluidized bed to investigate the changes in particle sizes. Experiments were carried out in the bed with a different mass fraction of coarser particles at different superficial gas velocities, and probe heights. The S-statistic test evaluates the dimensionless squared distance between two attractors reconstructed from time series of vibration signa...

Early Detection of Agglomeration in Fluidized Bed Polymerisation Reactors

Polyethylene (PE) and polypropylene (PP) make up for a large part of the total worldwide polymer production. Originally, both polymers were often produced in solution processes. However, fluidized bed reactors for polyethylene and polypropylene production gain increasing industrial interest because of the relatively low production costs, the ability to produce a wide range of polymer grades, an...

Hydrodynamic Characteristics of Dry Beneficiation of Iron Ore and Coal in a Fast Fluidized Bed

Iron ore and coal are the two major important raw materials being used in Iron making industries. Usually ore fines containing around 5% Alumina are rejected due to higher proportion of alumina. Therefore, a technology or process which may reduce the alumina content by 2% by beneficiation process will be highly attractive . In addition fine coals with ash content is used nearly 12% is directly ...
