Low-pressure absorption of CO2 from flue gas

Case study accomplished 95% sequestration using methyldiethanolamine aqueous solution

Tellini, M., Centola, P., Politecnico di Milano

Over 60% of carbon dioxide (CO2) sent to the atmosphere comes from fired heaters and utility or industrial power systems based on fossil-fuel combustion.1 The industrial capture of CO2 from emissions is possible with low pressure solvent absorption, a simple process operation that becomes particularly important for combustion furnaces, burners and incinerators. Traditionally, the absorption of acidic gases has been done under pressure with amine solutions, but typical combustion flue gases have large flowrates. Inert N2 is the bulk constituent and CO2 is generally diluted to 10% vol–15% vol. Fig. 1 shows the example of a tenfold polytropic compression at the 80% optimistic efficiency fo
