Carbon capture and storage (CCS) is the most indicated technology to decrease CO2 emission from fossil fuels sources to atmosphere. Also, CO2 separated from flue gases can be used in enhanced oil recovery (EOR) operations where CO2 is injected into oil reservoirs to increase mobility of oil and reservoir recovery. Pure CO2 has many applications in food/beverage and different chemical industries such as urea and fertilizer production. CCS consists of three basic stages: (a) separation of CO2, (b) transportation, and (c) storage. CO2 separation is a major stage in CCS. There are three major approaches for CCS: pre-combustion capture, oxy-fuel process, and post-combustion capture. Because of the importance in selecting suitable process for CO2 separation, in this paper various technologies for this purpose have been focused.
