A feasibility study on a novel stone dust looping

2015-12-1  The stone dust particles rich in calcium are looped between the carbonator and calciner reactors and hence the origin of the process name, stone dust looping. Thermodynamically, the calcination reaction may occur at temperatures between 625 and 800 °C by maintaining appropriate CO 2 partial pressure in the carbonator.
