The industrial revolution was caused to develop the world with technological advancements and it affects badly to the environment. These reasons cause the development of different systems to control the emission of different gasses to the environment. At present CO2 concentration in air is considerably high and it needs to be reduced before it release to the environment. For that purpose, CO2 capturing methods have introduced for industries and power plants. There are several methods to capture CO2 and only post combustion capturing methods will discuss in this article. Post-combustion capturing methods like Chemical absorption, Physical absorption, Membrane separation, Cryogenic separation, and Adsorption methods are discussed in this article. These systems will describe in detail with advantages and disadvantages.
