Project Abstract
Interconnected fluidized bed reactors play an important role in a variety of industrial applications, like Partial Oxidation (POX), Fluid Catalytic Cracking (FCC) and Chemical Looping Combustion (CLC). In these processes, a reactive material is looped between two reactors, being used in the first and regenerated in the other.

The exemplary CLC is a carbon capture process, where carbon dioxide is separated from flue gases via this system of fluidized bed reactors. Between these two fluidized bed reactors oxygen carrying (OC) material is circulated, taking in oxygen in an Air Reactor, releasing it in the Fuel Reactor.

For modelling of this strongly coupled system, a dynamic flowsheet simulation environment is applied. For capturing dynamic effects within the system like load alternation, attrition and startup as well as shut-down procedures, simplified models are derived and experimentally evaluated and parameterized.
