It is widely accepted today that global concentration of carbon dioxide (CO 2 ) 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 CO 2 . 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 CO 2 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
