Carbon dioxide capture by [emim][Ac] ionic liquid in a polysulfone hollow fiber membrane contactor

CO2 emissions have to be controlled and reduced in order to avoid greenhouse effect. This work reports an analysis of the efficiency of CO2 separation using a hollow fiber membrane contactor and an ionic liquid.
