CO2 and SO2 removal from flue gas and waste streams

Recently, we reviewed the state of membrane separation in post-combustion CO₂ capture, highlighting the potential of membrane technology despite challenges such as polymer aging and sensitivity to minor species (SO₂, NO_X, humidity). We experimentally explore various membrane compositions and configurations to achieve efficient gas separation of CO₂ as well as SO₂. For instance, we examine the separation performance of membranes blended with ionic liquids or using water-swollen composite membranes, observing increased permeability and selectivity. Furthermore, we assessed the potential of ultrapermeable membranes based on polymers of intrinsic microporosity for SO₂ and CO₂ removal in complex gas mixtures resembling industrial conditions. Additionally, membrane technologies were reviewed for their potential in simultaneous chemical transformations combining separation catalytic processes.
