Comparative Studies of Energy Saving Performance for CO2 Capture

Carbon dioxide (CO₂) capture, storage and utilization technology has attracted recent attention as a technology to reduce greenhouse gas emissions and mitigate global warming. On the contrary, CO₂ demands have been increased for inactive gases, dry ice in markets and refrigerant instead of Chlorofluorocarbons (CFCs). So far we have captured CO₂ from the source with high CO₂ concentration due to the limitation of CO₂ demands. However, we will have to capture CO₂ from the source with lower CO₂ concentration due to recent diversification of CO₂ demands as well. Therefore, it is necessary to design suitable CO₂ capture processes for satisfying to several CO2 demands and sources.
In this research, therefore, characteristics of several CO₂ capture processes have been investigated and the required energy for these processes have been compared from the process design point of view in order to create a tool for designing suitable processes by simulations and experiments.
