Fluidized beds are used in many industrial applications because of their excellent mixing and heat transfer characteristics. Historically, the design of fluidized bed reactors has been guided by correlations and rules of thumb, and troubleshooting poorly performing reactors remains challenging. The development of the Computational Particle Fluid Dynamics (CPFD®) numerical approach, and its implementation in the commercial software Barracuda Virtual Reactor®, provides operators and designers of fluidized bed reactors with a new tool for making engineering decisions. This presentation includes case studies of real-world examples of industrial systems that have been simulated using Virtual ReactorTM. The problems experienced in these systems include erosion from particle impact on vessel walls, afterburn (a specific type of undesirable reactor temperature profile), and maldistribution of gas flow through the fluidized bed with negative impact on emissions. In each case, design changes were implemented based on insights from the computational model, and the operator has reported improved performance and reliability resulting from the change. |
