The Need

The urgent need to mitigate climate change has driven the demand for efficient carbon capture technologies. Current methods often fall short in achieving high capture rates and purity levels, especially for industrial applications. This technology addresses the critical need for a scalable, cost-effective solution to capture and purify CO₂ from flue gases, significantly reducing greenhouse gas emissions.

The Technology

Developed by researchers at The Ohio State University, this innovative three-stage membrane process captures up to 99% of CO₂ from flue gases. The system integrates a primary capture unit, an enriching cascade, and a polishing stage to achieve high capture efficiency and CO₂ purity. The process includes advanced features like SO₂ and NO₂ polishing, heat integration, and CO₂ compression and dehydration.

Commercial Applications

• Cement production plants
• Natural gas combined cycle (NGCC) power plants
• Coal-fired power plants

Benefits/Advantages

• Achieves up to 99% CO₂ capture with high purity
• Lower parasitic energy demand compared to steam-based systems
• Competitive cost and performance compared to existing technologies
