Separation of mixtures of gases by new polymeric membranes and modelling of the process

Combustion of fossil fuels stands as the predominant method globally for generating heat and power, constituting the largest contributor to greenhouse gas (GHG) emissions, including carbon dioxide, NOX, and sulfur dioxide. Additionally, GHGs stem from various industrial activities such as metal production, glassmaking, cement manufacturing, ceramics, sewage sludge drying, and waste incineration. In this study, we propose employing advanced membrane technology for flue gas purification. The membranes will use polymers of intrinsic microporosity and incorporate novel fillers like ionic liquids and MOFs to develop mixed matrix membranes. Our primary objective is the removal of a broad spectrum of GHGs and gaseous pollutants (e.g. CO₂, SO₂, NO_x) from simulated flue gases. The project includes the development of a new mathematical model to predict and describe membrane purification efficiency. Subsequently, the most effective membranes will undergo testing with real flue gas to determine optimal purification parameters, (feed flow rate, temperature, and upstream and downstream pressures).
