Simulation of the Energy Consumption of CO2 Capture by Aqueous Monoethanolamine in Pilot Plant

Monoethanolamine is a conventional solvent used for capturing carbon dioxide from coal fired power plants. Its stable performance makes it a good benchmark to explore other absorbent or technological processes. In this paper, process simulations based on Aspen Plus are conducted to identify how operating parameters influence energy consumption and efficiency for the carbon dioxide capture. Experimental results carried out in a pilot plant will be reported along with the comparisons to the simulated results. Comparative discussion against existing publications in the same area regarding the simulation validity is also carried out.
