Abstract

Presented on Thursday 23 May: Session 27

Reducing emissions from the industrial and fossil fuel-based power sectors is crucial to achieving net zero emissions. These sectors contribute to ~60% of global carbon dioxide (CO2) emissions. However, there are several challenges that current CO2 capture technology faces. The use of coal in steel and cement industries produces flue gases with high CO2 content but also with nitrogen and sulfur oxides (NOx and SOx) as impurities. These impurities cause faster degradation of amine-based solvents in the current CO2 capture system. Additionally, capturing CO2 from flue gases from the hard-to-abate sector, such as steel plants, is complex as it is not easy to capture CO2 from multiple sources and different CO2 concentration flue gas streams. For cement and other kiln processes, limited availability of water/steam can add to the difficulty and cost of CO2 capture. CO2CRC’s HyCaps process, an efficient and compact hybrid of solvent absorption and membrane technology, overcomes some of these challenges. It takes advantage of the capture efficiency of the solvent system, controlled flow regime and high surface-to-volume ratio of membrane technology. The mode of interaction between gas and liquid in HyCaps limits solvent exposure to NOx and SOx, reducing solvent degradation. In HyCaps, as solvent is regenerated at a lower temperature, low-quality, low-cost waste heat can be effectively utilised to reduce operational expenditure. Successful trials at three different industrial setups and preliminary techno-economic analysis from test trial data show the HyCaps process has the potential to offer very competitive capture solutions for various industrial settings.
