“…Therefore, changing the concentration of MDEA has little effect on CO 2 absorption. [39] In addition, it can be found from Figure 7 that the absorption enhancement factor of blended amine nanofluids is markedly higher than that of MEA nanofluids. Moreover, the higher the concentration of MDEA in blended amine, the larger the enhancement factor E, and the more evident the enhancement effect of the nanoparticles on CO 2 absorption.…”

Nanofluids promote the application of nanotechnology in the mass transfer process, which can effectively reduce mass transfer resistance and increase the gas–liquid mass transfer rate. A bubbling absorption system was used to explore the CO2 absorption performance of methyldiethanolamine (MDEA) and monoethanolamine (MEA) blended nanofluids. TiO2 nanoparticles and sodium polyacrylate (ASAP) surfactant were added to MDEA‐MEA aqueous solutions to prepare nanofluids. The effects of MDEA concentration, MEA concentration, blended amine ratio, and nanoparticle solid content on CO2 capture performance were investigated, respectively. The study found that, compared with single‐component MEA/MDEA solutions, nanofluids have a more significant enhancement in CO2 absorption of blended amines. The increase of MEA concentration in blended amine has a negative effect on the enhanced CO2 absorption of TiO2 nanoparticles. The enhancement factor of MDEA‐MEA nanofluids at each solid content is higher than that of two single‐component nanofluids. The best solid content of TiO2 nanoparticles in the MDEA‐MEA system is 0.6 g/L, while the enhancement factor E in 25% MDEA + 5% MEA nanofluids can reach up to 1.36. Finally, a new empirical formula was proposed to predict the enhancement factor and optimum solid content of TiO2‐MEA/MDEA nanofluids.

Function S-rough sets are defined by R-function equivalence class, which have dynamic characteristic. Function S-rough sets have dynamic characteristic, law characteristic and law-hiding characteristic. Function S-rough sets can generate f-hiding law and f -hiding law. By engrafting, crossing, and penetrating between the information security theory and function S-rough sets, the security hiding and the authentication of f -hiding law and f -hiding law are given respectively in this paper. The fusion and share between function S-rough sets and information security theory is a new research direction of the application of information law in information system.
