Corrugated packing is a vital component in Carbon Capture and Storage (CCS) systems, enabling efficient CO₂ separation from industrial flue gases. Its unique corrugated design maximizes specific surface area, facilitating optimal gas-liquid contact—key for high carbon capture rates in amine absorption and adsorption processes.

Design and Material Selection for CCS Corrugated Packing
The performance of corrugated packing in CCS hinges on structural design and material compatibility. Its interlocking, angled wave pattern creates a continuous, open flow path for gases and liquids, minimizing channeling and dead spaces. Common materials include stainless steel (316L grade for corrosion resistance), polypropylene (PP) for chemical inertness, and ceramic for high-temperature tolerance. These materials ensure durability in amine-rich environments, where CO₂ absorption often involves aggressive solvents. The packing’s uniform structure ensures consistent gas distribution, reducing pressure drop and enhancing overall system efficiency.
Key Advantages and Industrial Applications
Corrugated packing offers distinct benefits for CCS, including superior mass transfer efficiency, low energy consumption, and long-term operational stability. In post-combustion CCS, it is widely used in absorption towers where amine solutions (e.g., monoethanolamine, MEA) selectively bind CO₂. A recent industrial case study at a coal-fired power plant showed that replacing traditional packed beds with metal corrugated packing increased CO₂ capture rate by 22% while reducing energy use by 15%. Its adaptability also suits pre-combustion CCS (e.g., gas shift processes) and oxy-fuel CCS (e.g., pure O₂ combustion), making it a versatile solution for diverse industrial decarbonization needs.
