| description | In this research, the intensification of the CO2 absorption process in methyl diethanolamine solution through ultrasound waves and nanofluids was studied in a batch system. A number of nanoparticles were utilised to evaluate the effects of the nanoparticle type. Based on the results, both application of the nanofluids and the ultrasound waves were effective in the intensification of the absorption process. However, the intensification resulting from the ultrasound waves utilisation, was much more infuential, which was related to the different mechanisms governing these two intensification methods. The results showed that among different nanofluids, only in the case of SiO2 containing nanofluids, simultaneous utilizing the nanofluids and ultrasound waves led to a greater enhancement in the CO2 absorption process in comparison to utilisation of solely ultrasound wave. Based upon the experimental results, the maximum enhancement in the absorption rate was achieved for the nanofluids containing 0.1 wt% SiO2 under ultrasonic irradiation with a power of 3.9 W by 638.3 %. The difference in the performance of the nano-additives in the ultrasound-assisted absorption process is related to their different properties, such as density, morphology, and physicochemical properties. It was also observed that increasing the nanoparticle loading more than a certain amount reduces the influence of the nanoparticles upon the ultrasound-assisted absorption process. This is due to ultrasound wave propagation weakening at higher concentrations of the nanoparticles, which causes the positive effects of the nanoparticles to be diminished. The performances of the nanoparticles were also evaluated by examining the height of the acoustic fountain. |
