AI Technical Summary
Technical Problem
Current ammonia-based solvent CO2 capture processes, such as the Mixed Salt Process (MSP), are inefficient in terms of energy consumption and suffer from ammonia slip, leading to reduced CO2 capture performance and increased equipment costs.
Method used
A process and system that utilizes a CO2-partially-enriched solvent for ammonia slip abatement, incorporating sequential absorber sections with solvent cooling and reintroduction to maintain driving forces, thereby reducing ammonia emissions and energy consumption.
Benefits of technology
The process enhances CO2 removal efficiency, minimizes ammonia slip, and reduces the required gas-liquid contacting device volume and steam consumption, achieving cost and energy savings while maintaining high CO2 capture performance.
