“…Nanofluids (NFs) are uniform and stable suspension systems formed by dispersing a small amount of nanoparticles into base fluid . In recent years, numerous researchers have found that NFs have great potential for enhancing mass and heat transfer performance. , NFs have been used as new absorbents for the removal of CO 2 . − However, the use of NFs to remove H 2 S has rarely been investigated. According to reports, nanoparticles (carbon nanotubes, CuO, graphene oxide, and so on) were introduced into different base solutions (water, MDEA, and so on) to obtain different NF systems, and it was found that they have significant enhancement performance.…”

Heteropoly compounds were dissolved in ionic liquids to obtain heteropoly compound/ionic liquid solutions. SiO 2 nanoparticles with different mass ratios were introduced into the solutions described above to obtain nanofluids. The desulfurization and regeneration performances of the nanofluids have been explored by dynamic H 2 S absorption experiments. The results showed that the optimal ratio of SiO 2 nanoparticles was confirmed to be 0.05% at 150 °C and the desulfurization efficiency of the nanofluid remained above 97% at 480 min. The nanofluids exhibited lower desulfurization performance at 100 °C than that at 150 °C. It is noteworthy that heteropoly blue has a self-catalytic effect on the absorption process of H 2 S. The results of characterizations revealed that SiO 2 nanoparticles in the nanofluids were covered by heteropoly compounds and sulfur. The morphology of SiO 2 nanoparticles showed no significant change in the absorption−regeneration process. The nanofluids had stable and high desulfurization performance at high temperature and could be regenerated by air easily.

Heat exchangers are crucial in transferring heat and finding applications across various industries. Numerous strategies have been devised to improve and optimize the heat transfer process within these systems. Among these, passive methods have garnered significant attention for their ability to operate without external power consumption. This article examines the recent experimental and computational studies conducted by researchers since 2018 on passive enhancement techniques, especially twisted tape, wire coil, swirl flow generator, and others, to boost the thermal efficiency of heat exchangers and aid designers in adopting passive augmentation methods for compact heat exchangers. Recently, researchers' new class of flow maldistribution devices, referred to as swirl flow devices, has gained attention; which enhances convective heat transfer by introducing swirl into the main flow and disrupting the boundary layer at the tube surface through alterations in surface geometry. Twisted tape inserts are devices that demonstrate better performance in laminar flow compared to turbulent flow. Conversely, other passive techniques like ribs, conical nozzles, and conical rings are generally more effective in turbulent flow than laminar flow. A recent research trend is the utilization of nanofluids in combination with other passive heat transfer enhancement techniques like turbulators, ribs, and twisted tape inserts in heat exchangers, which can reduce exergy losses and improve overall convective heat transfer coefficient and effectiveness of heat exchanger.
