Advances in Pressure Swing Adsorption for Carbon Dioxide Separation: Materials, Process Modeling, and Applications

Carbon dioxide capture and storage (CCS) is widely recognized as a key strategy for mitigating greenhouse gas emissions and combating climate change. Among the available technologies, pressure swing adsorption (PSA) has emerged as a promising option due to its simplicity, energy efficiency, and adaptability to diverse industrial applications. This review provides a comprehensive assessment of recent advancements in PSA technology, focusing on both adsorbent materials and process design. Recent advances in adsorbent materials and hybrid adsorbents are discussed in details. The most widely used absorbents for CO2 separation are developed zeolites, which have recovery and purity of up to 85% and 97%, respectively. However, metal-organic frameworks (MOFs) have recently attracted attention due to their special features and capabilities (purity up to 99.93%, recovery up to 92.7%). Novel process configurations and hybrid PSA-based systems are also explored for their potential to enhance performance while reducing energy consumption. Case studies from bench scale, pilot-scale and industrial-scale systems are presented to illustrate the maturity and scalability of PSA systems. Development in process design and system configuration were developed to reach high recovery of more than 97% and purity of 99.5%. The role of mathematical modeling and simulation for evaluation and optimization of PSA system performance is addressed.
