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

Abstract:

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.
