Abstract

Environmentalists and climate specialists today recognize need for techniques that remove CO2 from atmosphere to mitigate changes to the global climate caused by over a century of expanding anthropogenic CO2 emissions. Traditional modes of carbon capture; such as pre-combustion and post-combustion CO2 capture from large point sources can help to slow the rate of increase of atmospheric CO2 concentration. However, the direct removal of CO2 from the air, or “direct air capture” (DAC), can actually reduce the global atmospheric CO2 concentration. The past decade has seen a steep rise in use of chemical sorbents that are cycled through sorption and desorption for CO2 removal from ultra-dilute gases such as air. This paper provides a historical overview of the field of DAC, along with an exhaustive description of the use of chemical sorbents and its alternative uses, applications in CO2 Capturing. When developing technologies, there are number of steps includes; the development of commercial process, optimization of process, scale-up from the bench to a pilot plant, and from the pilot plant to the full scale process. Reasons for these critical steps include; understanding potential waste streams, examination of macro-processes, process interactions, process variations, process controls, development of standard operating procedures, etc. Solvents and solid sorbents that interact strongly with CO2 are described, including basic solvents, supported amine and ammonium materials, and “metal organic frameworks” (MOFs), as the primary classes of chemical sorbents. Hypothetical processes for the deployment of such sorbents are discussed, concluded that many new materials could play role in emerging DAC techniques.
