Abstract

The continuous increment of energy demand and carbon fuel utilization contribute at CO2 emission in atmosphere, causing an increment of environmental temperature with consecutive climatic change. Several technologies have been proposed for reducing CO2 emission, from energetic efficiency to the development of renewable energies and carbon capture and storage (CCS). CCS technologies focus on the reduction of CO2 in the atmosphere or from industrial flue gases, by separating, transporting, and storing CO2 into underground reservoirs. The separation of CO2 from flue gas is an important aspect of CCS. CO2 can be typically separated using a variety of techniques, depending on the emission source: after the fuel combustion (e.g., coal power plants) or in precombustion conditions (e.g., gasification/water-gas shift reactions). This chapter emphasises on the CO2 capture from precombustion streams with the aid of membranes, in order to give an update on the technology development.
