Novel measurement of solids circulation rate in pilot

A number of fluidized bed reactor processes operating at high temperature require that solid particles be circulated back and forth between two reactor vessels. Since the circulation rate strongly affects mass and energy balances, and therefore greatly influences hydrodynamics and performance of the system, a reliable technique for its accurate measurement would be helpful in monitoring and

Performance of Natural Sorbents during Calcium Looping

Six European limestones and one European dolomite were tested for CO2 capture by simulating calcium looping cycles both in a labscale fluidized bed (FB) and in a thermogravimetric (TG) apparatus. The FB tests were carried out under severe conditions representative of a process with calcination in an oxyfiring environment (T = 940 °C, 70% CO2). The TG tests were performed with a somewhat

Investigation and analysis of a fluidized bed dryer by

Dec 14, · Fluidized bed drying, granulation and coating are important processes in pharmaceutical industries for solid dose formulation. The main advantage of using fluidized beds is that they provide efficient heat and mass transfer and can mix and agglomerate excipients and active material ingredients to produce uniform blends of particles (Walker et al. ).

82. Metal Processing and Metal Working Industry

Four processing stages are generally used in hydrometallurgic zinc refining: calcining, leaching, purification and electrowinning. Calcining, or roasting, is a hightemperature process (700 to °C) that converts zinc sulphide concentrate to an impure zinc oxide called calcine. Roaster types include multiplehearth, suspension or fluidizedbed.
