Emissions of carbon dioxide (CO2) and other greenhouse gases (GHG) must be reduced to minimize global warming. The primary sources of CO2 emissions are power plants (coal and gas), transportation (burning fuels), and chemical industries (cement and aluminum). Therefore, it is essential to capture CO2 to keep emissions levels up to standards. Various techniques have been proposed for capturing carbon. Pre-combustion, post-combustion, oxy-fuel combustion are the three main types of carbon capture technologies. This article presents a description of the CO2 removal process of post-combustion. Post-combustion grip combusted fossil fuels to produce energy, and CO2 is removed from the gas after combustion. There are several options for post-combustion carbon capture from the flue gas. That processes and their advantages and disadvantages are described in this review article.
