CO2 solvent removal plant showing the solvent absorption equipment and process.
Solvent-based absorption CO2 capture is a cyclical process re-using solvent and waste heat.
Schematic representation of three of the different possible mechanisms for membrane gas separation (after Scholes, Kentish and Stevens).
Membrane gas separation modules can be constructed for efficiency of space.
Membrane gas absorption: hollow fibre module.
Gas separation membrane: flatsheet module.
Zeolites are hydrated aluminosilicate minerals which form regular, porous structures and act as a molecular sieve. They may be readily modified to include a large variety of metal cations through a simple ion-exchange process. These modifications lead to large changes in CO2 sorption capacity, selectivity and water tolerance.
Melbourne University is working on new technologies for capturing and separating carbon dioxide from other gases.
