PERSPECTIVES OF REMOVING CARBON DIOXIDE FROM FLUE GASES OF THERMAL POWER PLANTS WITH OBTAINING VALUABLE CHEMICALS
Published: 31 May 2015
Abstract: Removing carbon dioxide from flue gases with subsequent fixation of CO2 into valuable chemicals is the most effective way of reducing emission of this "greenhouse gas" by thermal power plants. Selecting the direction of CO2 transformation into chemical compounds is dependent on the technology applied for the purification of flue gases (chemisorption, physical absorption, etc.). In the case of using the method of monoethanolamine chemisorption, there is proposed to carry out the hydrogenation of recovered carbon dioxide to obtain formic acid and methyl formate. When removing CO2 from flue gases by the method of physical absorption, there is the most appropriate considered the transformation of organic carbon dioxide into organic carbonates (propylene carbonate, glycerol carbonate).
Keywords: carbon dioxide utilization, flue gases purification, carbon dioxide hydrogenation, formic acid, methyl formate, propylene carbonate, glycerol carbonat
