To increase the applicability of a rotor–stator reactor (RSR) in gas–liquid mass transfer processes, the effective mass transfer area (ae) and the local gas-side mass transfer coefficient (kG) 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 ae. The effects of operating conditions and stator rings on these mass transfer parameters were investigated. The experimental results showed that ae and kG in the RSR with stator rings were higher than those in the RSR without stator rings by 17–30 and 1–9%, respectively. ae in the RSR with stator rings was 3.4% lower than that in a rotating packed bed, but kG 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 ek 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。
