Top Use Cases
- Post-combustion Carbon Capture in Power Plants
Membranes enable efficient CO₂ removal from flue gases after fossil fuel combustion, often as a retrofit solution. They offer low energy use and compact design, providing a cost-effective, modular alternative to solvent-based methods helpful in lowering industrial emissions while minimizing infrastructure disruption.
2. Biogas Upgrading for Renewable Energy
CO₂ separation membranes purify biogas by removing carbon dioxide and impurities to produce high-quality biomethane. Faster, energy-efficient processing with low operating costs makes them ideal for transforming organic waste into cleaner fuel, supporting renewable energy and sustainability goals.
3. Natural Gas Processing and Sweetening
In gas processing, membranes remove CO₂ and other acids (e.g., H₂S) from natural gas. This “sweetening” ensures the fuel meets pipeline or liquefaction standards, often for enhanced oil recovery or clean energy use without the energy burden of cryogenic or chemical methods.
4. Modular Membrane Reactors for Chemical Synthesis
Membrane-equipped reactors remove products like CO₂ as they form during synthesis reactions. This shifts reaction equilibrium, improves yield, and cuts energy needs especially useful in high-pressure or high-temperature environments, promoting efficient, cleaner chemical production.
5. Hybrid Systems for Hydrogen & Biogas Markets
Membranes team up with technologies like pressure swing adsorption in hybrid systems to purify hydrogen or upgrade biogas. These combinations enhance selectivity, reduce energy consumption, and enable cleaner production pathways for hydrogen fuel and renewable gas markets.
