In this study, tri-ethylene glycol (TEG) based nanofluids of carbon nanotubes (CNT), silica (SiO₂) and aluminum oxide (Al₂O₃) in different weight percents of 0.01 and 0.05 wt% were employed to improve the properties of TEG for water vapor absorption in a hollow fiber membrane contactor (HFMC). To do so, the impact of various operational parameters including nanofluid type, nanoparticles (NPs) concentration, liquid and gas flow rate on water vapor separation were elucidated. According to obtained results, CNT nanofluid was more capable on water vapor absorption toward SiO₂ and Al₂O₃, so that the injection of CNT nanofluid led to water vapor absorption enhancement up to 10.8 % as compared to TEG solution alone. The results also indicated that the gas flow rate has an inverse relationship with the amount of water vapor absorption efficiency, whereas increasing the liquid flow rate has no tangible effect on absorption efficiency, which is because of the very high solubility of water vapor in TEG. Ultimately, dynamic light scattering (DLS) analysis was carried out to evaluate the stability of nanofluids and size distribution of nanostructures in the base fluid.

在这项研究中，采用三甘醇（TEG）基纳米流体的碳纳米管（CNT），二氧化硅（SiO ₂）和氧化铝（Al ₂ O ₃）分别以0.01和0.05 wt％的重量百分比改善了性能。 TEG用于中空纤维膜接触器（HFMC）中的水蒸气吸收。为此，阐明了包括纳米流体类型，纳米颗粒（NPs）浓度，液体和气体流速在内的各种操作参数对水蒸气分离的影响。根据得到的结果，CNT纳米流体对SiO ₂和Al ₂ O _3的水蒸气吸收能力更强。，因此与单独的TEG溶液相比，CNT纳米流体的注入导致水蒸气吸收增强高达10.8％。结果还表明，气体流速与水蒸气吸收效率的量成反比，而增加液体流速对吸收效率没有明显的影响，这是因为水蒸气在TEG中的溶解度非常高。最终，进行了动态光散射（DLS）分析以评估纳米流体在基础流体中的稳定性和纳米结构的尺寸分布。
