Abstract: Carbon capture, utilization, and storage (CCUS) is a crucial strategy for achieving CO2 emission reduction targets and mitigating the impacts of global warming and climate change. Among various CCUS technologies, chemical absorption of CO2 has proven to be a mature and widely-used technique in various industrial sectors. However, the current CO2 chemical absorption process involves large-scale equipment with low efficiencies, making it difficult to control. To address these issues, microfluidic devices have emerged as a promising technology to intensify the CO2 absorption process by providing a smaller required volume, enhanced mass transfer, cleaner and safer operations, higher productivity, and more efficient energy use.
