Abstract

To mitigate the effects of climate change, novel carbon capture technologies need to be developed. Since 2020, a new solution has been to adopt an energy-efficient combination of “amine blend + heterogeneous catalysts” in large CCUS demonstration plants. This study adopted the specific tri-solvent MEA-EAE-AMP and solid catalysts CaSO₄, HND-580, and HND-8 in a novel bench-scale pilot plant with hot oil as the heat source. Three key parameters were investigated—absorption efficiency (AE), cyclic capacity (CC), and heat duty (HD)—to analyze the technology under a steady state. The results indicated that the solid acid significantly reduced α_lean and the solid base increased αrich, while the CC was increased and HD was reduced to its minimum at 2.47 GJ/tCO₂ and at optimized doses of the catalysts, 40 g CaSO₄ and 100 HND-580. These results verified another energy-efficient solution that could be further scaled up into an industrial amine scrubbing pilot plant.
