Precipitation regime for selected amino acid salts for CO2 capture from flue gases

Protonation constants of amino acid salts at 298-353 K

Since there is no flue-gas desulfurization facility (FGD) in Australian Power Plants, the temperatures of flue gases from the plants range from 393–433 K which is much higher than the absorption temperatures in a typical post combustion CO2 capture (PCC) process. The additional cooling systems and equipments are required to cool flue gases. This adds to the cost, and water and energy consumptio...

Experimental Studies of CO2 Capturing from the Flue Gases

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

A computational investigation on the structural features of alkanolamine solvents for CO2 capture process from power plant flue gas

Flue gas treatment for CO2 capture

This report is in two sections: the first describes the flue gas and its treatment in post-combustion capture and the second covers the flue gas in oxyfuel combustion capture. The main components of the flue gas in pulverised coal combustion for postcombustion capture are CO2, N2, O2 and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The ...

High-throughput screening of metal-porphyrin-like graphenes for selective capture of carbon dioxide

Nanostructured materials, such as zeolites and metal-organic frameworks, have been considered to capture CO2. However, their application has been limited largely because they exhibit poor selectivity for flue gases and low capture capacity under low pressures. We perform a high-throughput screening for selective CO2 capture from flue gases by using first principles thermodynamics. We find that ...
