International community shouts out technology

Every year the Global CCS Institute compiles a report outlining the latest carbon capture and storage technologies that are available on the global market. These technologies and others are bringing us closer to carbon neutrality. Among the 120 projects featured in the 2024 edition is a promising technology developed by InnoTech Alberta, in conjunction with Alberta Innovates, called Amine Intensification Process. 

The Amine Intensification Process (AIP) is an enhancement of traditional amine-based carbon capture technology. An amine is an organic compound derived from ammonia. Key developments include: 

• Alternative Absorption Tower: The use of high-efficiency structured packing materials in the absorption tower significantly increases the mass transfer efficiency by 30 percent and reduces pressure drop by 20 percent. This improvement allows for a more compact and efficient absorption column. 
• Microwave Heating: Implementing microwave heating for regenerating solvents presents a breakthrough method that offers instantaneous and volumetric heating. This approach reduces the energy cost of CO2 capture by releasing CO2 at lower temperatures and more quickly than traditional methods. 
• Water Lean Solvent: The adoption of organic solvents with lower specific heat and volatility, instead of water, cuts the energy requirements for CO2 capture in half. This significantly reduces the heat duty of the reboiler and mitigates solvent degradation, leading to improved efficiency and cost savings. 

Overall, these improvements lead to a 75 percent reduction in energy requirements compared to conventional amine-based processes, offering substantial cost-saving opportunities and aligning with global sustainability goals. The AIP enables industries to lower their carbon footprints more effectively and economically, positioning them as leaders in environmental stewardship.
