To increase the applicability of a rotor–stator reactor (RSR) in gas–liquid mass transfer processes, the effective mass transfer area (a_e) and the local gas-side mass transfer coefficient (k_G) in the RSR were measured by employing a NaOH solution to absorb CO₂ and SO₂, where gas radial velocity is required to be large enough to ignore the gas-side mass transfer resistance in determination of a_e. The effects of operating conditions and stator rings on these mass transfer parameters were investigated. The experimental results showed that a_e and k_G in the RSR with stator rings were higher than those in the RSR without stator rings by 17–30 and 1–9%, respectively. a_e in the RSR with stator rings was 3.4% lower than that in a rotating packed bed, but k_G in such RSR was higher than that in the rotating packed bed by 78.6%, suggesting that the RSR has great potential for industrial applications in the processes controlled by gas-side mass transfer.

转子-定子反应堆有效传质面积和气体侧局部传质系数的研究

为了提高转子-定子反应器 (RSR) 在气-液传质过程中_的_适用性，通过采用用于吸收 CO ₂和 SO ₂的 NaOH 溶液，其中气体径向速度需要足够大以忽略测定a _e时的气体侧传质阻力。研究了运行条件和定子环对这些传质参数的影响。实验结果表明，a _e和k _G有定子环的 RSR 比没有定子环的 RSR 分别高 17-30% 和 1-9%。带定子环的 RSR的 a _e比旋转填充床低 3.4%，但这种 RSR 中的k _G比旋转填充床高 78.6%，表明 RSR 在工业应用方面具有巨大潜力由气体侧传质控制的过程。
