Post-Combustion Carbon Capture Amine Reclamation
The ElectroSep® CO₂ Process™ For Carbon Capture
How it Works
Amine reclamation is a critical component of the overall capture process to maintain operational efficiency. Typically the carbon capture (CC) process prioritizes the bulk removal of CO₂ over low outlet CO₂ concentrations. For example, a CC project might remove 90% of the feed CO₂ but still end up with an outlet concentration of possibly 50,000 ppm or more.
Typical bulk systems often utilize tertiary amines as primary CO₂ buffering agents for high capture capacity and low degradation rates. Using primary or secondary amines, these systems can improve capture kinetics and overall capacity, but these amines are typically less stable than tertiary amines. Reclamation of these formulated CC amine systems can lead to very high amine losses–the ElectroSep CO₂ Process is different.
The ElectroSep CO₂ Process Targeting Carbon Capture Applications
The ElectroSep Process is composed of up to three independent stages to maximize efficiency and reduce waste:
1
ElectroSep patented pre-treatment process
- Significantly reduces amine loss, which is a major cost concern for CC amine systems.
- Significantly reduces the amine reclamation units size and associated utility consumptions and waste generation.
2
ElectroSep patented TL³® amine reclamation process
- Delivers industry leading performance and sustainability, while optimizing overall amine unit cost performance.
3
ElectroSep patented near-zero waste process
- Critical for sites with limited waste water disposal options
