To reduce the energy consumption for solvent regeneration in chemisorptions, a nanofluid-based direct non-aqueous gas stripping process was proposed for CO2 capture. Nanofluid solvents were prepared based on SiO2, TiO2 and γ-Al2O3 nanoparticles and monoethanolamine (MEA) solution, with pentane, hexane, and cyclohexane as the carrier gases, to study the CO2 desorption ability in the direct non-aqueous gas stripping process, and to analyze the regeneration rate, cycle load and related energy consumption. Results show that the nanofluid solvents prepared above are relatively stable. Compared with conventional stripping processes, optimum regeneration effects could be obtained with pentane as the carrier gas, when the regeneration energy could be lowered by more than 40%. © 2019, Editorial Department of Chinese Society of Power Engineering.
