Membrane pilot plant trials of CO2 separation from flue gas

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...

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

Sorbent attrition in a carbonation/calcination pilot plant for capturing CO2 from flue gases

There is increasing interest in CO2 looping cycles that involve the repeated calcination and carbonation of the sorbent as a way to capture CO2 from flue gases during the carbonation step and the generation of a pure stream of CO2 in the oxyfired calcination step. In particular, attrition of the material in these interconnected fluidized bed reactors is a problem of general concern. Attrition o...

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 ...
