CO2Rückgewinnung

CO2Rückgewinnung refers to the process of capturing carbon dioxide (CO2) from industrial emissions or the atmosphere for subsequent reuse or storage. This technology is a key component of carbon capture, utilization, and storage (CCUS) strategies aimed at mitigating climate change. Various methods exist for CO2Rückgewinnung, including absorption, adsorption, membrane separation, and cryogenic processes. Absorption, for instance, typically involves using liquid solvents that selectively absorb CO2. Adsorption utilizes solid materials that bind to CO2 molecules. Membrane technologies employ semi-permeable barriers that allow CO2 to pass through while retaining other gases. Cryogenic separation cools the gas stream to liquefy CO2.

The captured CO2 can then be utilized in a range of applications. This includes enhanced oil recovery (EOR), where CO2 is injected into oil reservoirs to increase oil production. It can also be used in the production of chemicals, fuels, and building materials, contributing to a circular economy. Alternatively, the captured CO2 can be permanently stored underground in geological formations, a process known as carbon sequestration. This approach aims to prevent CO2 from entering the atmosphere and contributing to global warming. CO2Rückgewinnung technologies are continuously being developed and improved to increase efficiency, reduce costs, and broaden their applicability across different industrial sectors. The economic viability and environmental effectiveness of these processes are subject to ongoing research and policy considerations.
