Abstract :
It is generally accepted that carbon capture and storage strategies will play a crucial role for mitigating CO2 emissions at short- and mid-term scenarios. In this study, a membrane gas absorption process was assessed as potential candidate method for CO2 capture in a Greek brick production industry. The membrane contactor pilot unit was installed near the flue, where a slip stream of the flue gases was continuously sampled and fed in the hollow fiber membrane module. A 0.25 M aqueous diethanolamine solution was used as a typical solvent for CO2 capture. The % CO2 removal was chosen as a typical performance indicator and the liquid to gas flow ratio was chosen as the main controlling variable of the process. The test results indicate that almost complete CO2 removal can be attained with a liquid to gas flow rate around 1, demonstrating the high potential of the proposed technology.
