Modeling and simulation of circulating fluidized bed reactors applied to a carbonation/calcination loop

- A fluid dynamic model for a gas-solid CFB consisting of two coupled riser reactors is developed.
- The model represents a step further in complexity from the conventional Kunii-Levenspiel type of models.
- Based on this model simulations reproduced the relevant experimental data in the literature.
- Simulation shows that sufficient heat integration between the two reactor units is very important.
- The model performs fairly well for the chemical loop process in question.
