摘      要：The mitigation of greenhouse gas emissions to acceptable levels is arguably the greatest environmental challenge these *** utilization of fossil fuels and forest destruction are main causes of CO_(2) increase in the *** dioxide sequestration that consists of separation,transportation and utilization or storage of CO_(2),is one way for reduction of its emission,in which the most costly section is *** methods can be used for carbon dioxide separation such as absorption,mem-brane separation,adsorption and cryogenic ***,technical and environmental issues should be considered in selection of the technology for particular *** dioxide concentration,temperature,pressure andflow rate are influential operating parameters in the selection of the appropriate separation ***,absorption is the worldwide industrial separa-tion *** researches are focused on developing new stable solvents and efficient column configuration with suitable internals to minimize pressure *** separation and adsorption(PSA type)are other long-term alternatives that can increase separation efficiency and decrease separation *** level of energy consumption in various separation methods are in the order:chemical absorptionphysical absorptionmembrane *** of high investment costs,current separation technologies are suitable for large concentrated *** the present paper,different processes for carbon dioxide separation are investigated and *** technologies and commercial plants for CO_(2) sequestration are provided.
