The calcium looping CO2 capture process using calcium oxide as a regenerable solid sorbent has been under development at the Industrial Technology Research Institute (ITRI) of Taiwan for several years. The 3‐kWth test facility built at ITRI is mainly composed of a fluidized‐bed carbonator and a rotary kiln calciner. The calcination efficiency, the CO2 capture efficiency, and operating stability were investigated. In addition, a cold model test facility has been constructed and a 1.9‐MWth pilot plant designed by ITRI is currently being erected. The combination of calcium looping and cement manufacturing process reduces the cost of adsorbent and calcination energy consumption. Calcium looping is a promising concept for post‐combustion CO2 capture applications. A long‐term test proved the stability and ease of operation of a 3‐kWth facility. Detailed design parameters of the 1.9‐MWth facility currently under construction in Taiwan are presented. The ambition of this pilot plant is to achieve a CO2 capture rate of 1 t h–1.
