TRABZUNI, F.. Simulation of titanium dioxide (TiO2) ore elutriation from chlorination fluidized bed reactors. J. S. Afr. Inst. Min. Metall. [online]. 2009, vol.109, n.2, pp.129-133. ISSN 2411-9717.

Elutriation of solid reactants from fluidized bed reactors can affect their process performance and efficiency greatly. Chlorination fluidized bed reactors for selective conversion of solid metal oxides to metal chlorides are used widely these days. This study provides a platform for a proper understanding of reactant solid haracteristics and solid shrinkage interaction with elutriation rate constants using multi-sized particles, sand-like, 'Geldart B' chloridable materials. The study has found that actual elutriation rates of the reactive system are influenced by complex parameters' interaction including bed diameter, reactor freeboard height, bed minimum fluidization velocity, and reactant's physical properties.
