Solid particles' recirculation distribution in calcium looping post-combustion carbon capture

- A formula for particle distribution in Ca looping was derived.
- The formula obeyed the law of conservation of mass, was fast and numerically stable.
- The formula is particularly relevant for enhanced or tailored sorbents.
- The formula was expanded to fit various Ca-looping process configurations.
- Various configurations were compared in terms of efficiency and heat penalty.
