The objective of this project is to explore the possibility of minimizing the cost of capture of CO2 from**combustion gases such as the gaseous emissions of a natural gas fired boiler, by combining two technologies.**In the considered hybrid process an enzymatic absorber system is preceded by a membrane separation system**which raises the CO2 concentration before enzymatic treatment. CO2 Solutions has already developed to**demonstration scale an enzymatic absorber. The Université Laval group has developed mixed matrix**membranes suitable for CO2/N2 gas mixtures. Combining the two processes may lower the cost of CO2**capture by both technologies.

该项目的目标是通过结合两种技术，探索将从燃烧气体（如天然气锅炉的气体排放）中捕获二氧化碳的成本降至最低的可能性。在考虑的混合过程中，酶吸收系统之前是膜分离系统**，在酶处理之前提高CO2浓度。CO2 Solutions已经开发出一种酶吸收剂，达到了示范规模。法国拉瓦尔大学研究小组开发了适用于二氧化碳/氮气混合气体的混合基质膜。将这两种方法结合起来可以降低两种技术捕获二氧化碳的成本。
