The Effects of Operation Parameters on CO2 Removal Efficiency by Membrane Method

On the membrane contactor test unit, chose monoethanolamine (MEA) as absorption solution to absorb CO2 of simulated flue gases, studied effects of operating parameters on CO2 capture. Operating parameters included initial CO2 contents in flue gas, flue gas flow and absorption solution flow. Experimental results showed that: the greater the absorption of fluid flow, the higher the CO2 removal rate;While the greater the flue gas flow or the higher the initial CO2 concentration in flue gas, the lower the CO2 removal rate. In order to study the influence of the regeneration solution on CO2 absorption efficiency, regeneration experiments were done. Since the loss of solvent in regeneration solution, CO2 removal efficiency by regeneration solution was lower than that by original absorption solution.
