In this research, a novel aqueous solvent, i.e., nanoparticle-enhanced ionic liquid (NEIL), is proposed for CO₂ capture by mixing of MEA as the base fluid and [Bmim]BF₄ ionic liquid and TiO₂ nanoparticles as chemical additives. Then, the flow hydrodynamics, mass transfer characteristics, and CO₂ absorption performance of the proposed solvent are investigated in a T-shaped microchannel structure by Computational Fluid Dynamics technique at steady-state condition. To present a detailed model, the Navier–Stokes and continuity equations are combined with a two-phase laminar flow module considering mass transfer between heterogeneous phases. Then, the effects of [Bmim]BF₄ and TiO₂ mass fraction on CO₂ loading, bubble formation, and velocity profile are investigated at different gas and liquid holdups at ionic liquid fraction 0 % to 10% and nanoparticle fraction 0 to 0.1%. It concludes that the purification fraction reaches a maximum at TiO₂ weight fraction 0.04% and applying solvent with high nanoparticle content decreases purification fraction. In general, the proposed solvent and the considered contactor present adequate performance to absorb CO₂ from the gas mixture.

在这项研究中，提出了一种新型的水性溶剂，即纳米颗粒增强型离子液体（NEIL），通过混合MEA作为基础液和[Bmim] BF ₄离子液体和TiO ₂纳米颗粒作为化学添加剂来捕获CO ₂。然后，通过计算流体动力学技术在稳态条件下，在T形微通道结构中研究了拟议溶剂的流动流体动力学，传质特性和CO ₂吸收性能。为了给出详细的模型，考虑了异相之间的质量转移，将Navier-Stokes和连续性方程与两相层流模块组合在一起。然后，[Bmim] BF ₄和TiO _2的作用研究了在离子液体分数为0％至10％和纳米粒子分数为0至0.1％的不同气体和液体滞留量下，CO ₂负载，气泡形成和速度分布的质量分数。结论是，当TiO _2的重量分数为0.04％时，纯化分数达到最大值，而使用具有高纳米颗粒含量的溶剂会降低纯化分数。通常，所提出的溶剂和所考虑的接触器表现出足够的性能以从气体混合物中吸收CO ₂。
