Application of pulsed membrane contactor for CO2 capturing from flue gas

Abstract

Climate change resulting from the emission of greenhouse gases, in particular CO2 into the atmosphere has become a global challenge in recent years. Post-combustion CO2 capture is an effective way to mitigate CO2 emissions from power plants. Gas-solvent hollow fibre membrane contactors have been introduced as a promising technology for post-combustion CO2 capture, as contactors combine the benefits of membrane technology with chemical absorption. Although the membrane acts as a permeable barrier adding further mass transfer resistance approximately by 40% to the contactor system, the membrane module provides 10-fold reduction in equipment size and 30 times higher interfacial area than that o..
