Which engineer knows how ethanolamine absorbs carbon dioxide?
Natural gas processing is widely used, right? You can download a book on natural gas processing from the internet; it will definitely contain detailed information on the subject.
The principle of carbon dioxide absorption by MDEA solution is likely similar to that of ethanolamine: Principle of carbon dioxide absorption by MDEA solution: CO2 + H2O → H+ + HCO3- (1) H+ + R2NCH3 → R2NCH3H+ (2) R2’NH+ + CO2 → R2’NCOOH (3) R2’NCOOH + R2NCH3 + H2O → R2’NH+R2CH3NH+HCO3- (4) (3) + (4): R2NCH3 + CO2 + H2O → R2CH3NH+HCO3- (5)
Low voltage and high voltage are different
