CO2 Capture from Flue Gas by Phase Transitional Absorption

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 ...

Solvent Formulation for CO2 Separation from Flue Gas Streams

CO2 separation using reactive solvents is considered to be a technically viable option for capturing of CO2 from flue gas streams. However, the cost of CO2 capture using conventional solvents such as aqueous solutions of monoethanolamine (MEA) is prohibitively high. Nearly half of the total cost is due to operational costs, of which about 70 to 80% can be contributed to the cost of regeneration...

Preparation of Graphene-amine Nanofluid for Absorption of Carbon Dioxide (CO2) and Hydrogen Sulfide (H2S) from a Natural Gas Stream in a Wetted Wall Column

    In this study, it was shown that how CO2 and H2S were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in Diehanolamine (DEA). Before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. In the expe...

Absorption of Carbon Dioxide in a Bubble-Column Scrubber

In the current stage over 85% of world energy demand is supplied by fossil fuels. Coal-fired plants discharged roughly 40% of the total CO2 are the main contributors in CO2 emissions (Kim & Kim, 2004; Yang et al., 2008). Environmental issues caused by exhaust green house gases (GHG) and toxics have become global problems. Through the past studies of five decades, increased GHG levels in atmosph...
