OVERVIEW OF CARBON DIOXIDE SEPARATION TECHNOLOGY

摘要

One of the most urgent environmental issues of our time is to lower the concentration of greenhouse gases in the atmosphere by decreasing CO_2 emission. Carbon capture and storage has been introduced as an option in reducing these harmful CO_2 emissions. CO_2 separation from gas streams has been done using a variety of physical, chemical and biological technologies and methods. These technologies allow large-scale CO_2 separation in different industries including coal-fired power plants, refinery and fertilizer industries. Hence, this article reviews different separation methods, such as absorption, adsorption, and membrane-based separation. Other concepts, such as biological separation are also introduced.
