Scaleup and hydrodynamics study of gas-solid spouted beds
… of the complex flow structure of gas-solid spouted bed is crucial for design, scale-up and performance. Advanced gas-solid optical probes were developed and used to evaluate different hydrodynamic parameters of spouted beds. These optical probes measure solids concentration, velocity and …

Sulfur coating of urea in shallow spouted beds
… nitrogen fertilizer, and its production in a spouted bed was investigated. SCU was produced by batch and continuous operations. Higher quality products were typically produced by the batch process, but at significantly lower production rates than the continuous process. In order to understand …

Solids mixing and segregation in a gas spout-fluid bed-effect of the distributor design
… assessment of a newer version of the spout-fluid bed where the gas is supplied from a common plenum and the distributor controls the operational phenomenon. Thus the main body of the work deals with the effect of the distributor design on the mixing and segregation of solids in a spout-filled bed. …

Experimental Evaluation of Innovative Catalytic Heat Exchangers for Energy-efficient Amine-based Post-combustion CO₂ Capture Processes
… Compared to the conventional fixed catalyst bed desorber, the JVC-EX using benchmark MEA solvent and solid acid catalyst HZSM-5 achieved approximately 30% catalytic enhancement, a 50% reduction in catalyst demand, and a 22% decrease in energy consumption while maintaining excellent …

Hydrodynamics, stability and scale-up of slot-rectangular spouted beds
Slot-rectangular spouted beds, with rectangular cross-section and slotted gas inlets, have been proposed as a solution to overcoming scale-up difficulties with conventional axisymmetric spouted beds. They can be utilized in gas/particle processes such as drying of coarse particles and coating of …

Computational Fluid Dynamics Modeling and Simulations of Fluidized Bed Reactors for Chemical Looping Combustion
… laboratory-scale experiment of a dual fluidized bed CLC system. The salient features of the fluidization behavior in the air reactor and fuel reactor beds representing a riser and a bubbling bed respectively are accurately captured in the simulation. This work is one of the first 3-D simulations …

Hydrodynamics and Transient Heat Transfer Characteristics in Fluidized and Spouted Beds
… studied in a small scale laboratory fluidized bed. Experiments were designed to capture field data on multiple slit jet gas distributor systems for the validation of computational models. Localized data was quantified through the use of several novel non-intrusive experimental measurement …
