To develop cost-effective CO₂ capture technology process intensification will play a vital role. In this work, the capabilities of a gas–liquid vortex reactor (GLVR) as novel process intensification equipment are evaluated by studying its interphase mass transfer parameters to build up the fundamentals for its future application to for example, CO₂ capture. The NaOH-CO₂ chemisorption system and Danckwerts' model are applied to obtain the effective interfacial area and liquid-side mass transfer coefficient. Results show that the gas–liquid contact in the GLVR is capable of both generating a large interfacial area in a small reactor volume and creating a region with high-energy dissipation to improve mass transfer. A comparison of the volumetric mass transfer coefficients with data reported in literature for conventional and intensified reactor types confirms a superior mass transfer efficiency and, most importantly, a favorable energetic efficiency of the GLVR.

气液涡流反应器中 CO2 的化学吸附：相间传质效率评估

开发具有成本效益的CO ₂捕获技术过程强化将发挥至关重要的作用。在这项工作中，通过研究其相间传质参数来评估气液涡流反应器 (GLVR) 作为新型工艺强化设备的能力，从而为其未来在 CO ₂捕集等方面的应用奠定基础。NaOH-CO ₂应用化学吸附系统和 Danckwerts 模型获得有效界面面积和液体侧传质系数。结果表明，GLVR 中的气液接触既能在小反应器体积内产生大的界面面积，又能产生高能量耗散区域以改善传质。体积传质系数与文献中报道的常规和强化反应器类型数据的比较证实了卓越的传质效率，最重要的是，GLVR 具有良好的能量效率。
