Abstract
Liquid solid circulating fluidised bed and its performance at various operating conditions have been critically reviewed and reported. Hydrodynamic includes pressure drop across the bed, phase hold up distribution, flow regime, flow structure of each phase and solid circulation rate. Detailed analysis of axial and radial solid distributions, average solid holdup, solid circulation rate, critical transitional velocity for solid at different densities and fluids at varying viscosities was reported. The effect of the increase in liquid viscosity during heat and mass transfer phenomena in LSCFB has to be studied extensively as the industrial processing fluids are highly viscous.
