Optimization of a hybrid membrane/enzyme CO2 capture process

The firm CO2 Solutions Inc (CSI) from Québec has developed an enzyme-accelerated CO2 capture technology which may be appended to a variety of gas scrubbing equipments. Simultaneously, our Université Laval research group has been working on membrane gas phase separations using polymeric hollow fibers and mixed matrix membranes. The objective of the present Engage proposal together with the Mitacs Accelerate program is to explore the possibility that a hybrid process allowing to concentrate CO2 to some intermediate concentration (for example 40-50% CO2) using a membrane module, before the gas is fed to the enzyme process would lead to some lower cost per ton of CO2.
