CO2 Separation from Flue Gases Using Different Types of Membranes

Mustafa J, Farhan M and Hussain M

The emission of greenhouse gases such as CO2 is the main cause of global warming. Its separation from different emission sources such as chemical industries, power stations etc. to reduce greenhouse effect has been a mutual interest of the world. Conventional processes such as absorption, cryogenic distillation and adsorption used for this purpose but there are some drawbacks such as high energy consumption, process complexity and high capital cost are major issues which need some efficient alternative technique to be worked on. The developing technique such as Membrane separation is highly compact, energy efficient, environmental friendly, scale-up flexible and possibly more economical than previously well-established technologies. The purpose of this review is to classify membrane separation process used for CO2 gas separation from flue gases. This review covers introduction of membrane includingpolymeric and inorganic membranes, provide recent advancements such as mixed matrix membranes, facilitated transport membranes and carbon membranes which have improved permeability and selectivity. This review also portraits the basic differences between different types of membranes used for CO2 separation, highlighted operating conditions for different membranes and mention further research possibilities in this field.
