It is widely accepted today that global concentration of carbon dioxide (CO2) in the atmosphere is increasing rapidly. The main method for separating this gas is the mineral carbonation process. In this process, hydrogen-rich stream is produced by the removal of CO2. A feasibility simulation study was conducted to evaluate the utilization of CaO used in the combustion of coal processing plant. The fluidized bed reactor of calcium looping process was simulated by Aspen Plus software. In addition, the evaluated of the energy and economic process was carried out with Aspen Energy Analyzer and Aspen Economics Analyzer, respectively. The results of the simulation show that the hydrogen purity can reach more than 84vol% and more than 98.96vol% of CO2 along with combustion of coal is captured with calcium looping process. The results of the study with Aspen Economics Analyzer show that the operating cost of the process is about 914350$/year and the cost of utilities is about 5508.4$/h.
