Experiments of hydrodynamic and gas liquid mass transfer were carried out in a bubble column of 19.4 cm internal diameter and of 4 m height. The liquid phase can be either tap water or a coalescence inhibitor system, using aqueous solutions of three alcohols (ethanol, 2-propanol and 1-butanol) with a volumetric concentration of 0.05% v/v and sodium dodecyl sulfate: SDS (10⁻³ mol/L) as an anionic surfactant. The hydrodynamic study involved placing wall pressure sensors in different axial positions of a bubble column to determine the gas hold-up in different regions and the influence of non-coalescing system on its evolution. The overall liquid movement induced by bubbles and the residence time distribution analysis of liquid phase was performed by using inductivity sensors. Gas hold-up results showed that the presence of the gas is more important in the zone far enough to the gas distributor (zone II). The results of the volumetric mass transfer coefficient (K_La) revealed that K_La decreased with the addition of alcohol, especially when the number of carbons in alcohol increased. K_La decreased more with the addition of anionic surfactant. It was also proven that a decrease in K_La was due to a decrease in K_L, which was due to a decrease of bubble rise velocity as well as of the diffusivity when alcohol or ionic surfactant was added. Correlations were developed linking gas holdup and gas-liquid mass transfer coefficient to superficial gas velocity and surface tension gradient.

在内径为19.4 cm，高为4 m的鼓泡塔中进行了流体动力和气液传质实验。液相可以是自来水或聚结抑制剂体系，使用三种醇（乙醇，2-丙醇和1-丁醇）的水溶液含0.05％V / V和十二烷基硫酸钠的体积浓度：SDS（10 ^{- 3}（mol / L）作为阴离子表面活性剂。流体力学研究包括将壁压传感器放置在鼓泡塔的不同轴向位置，以确定在不同区域的气体滞留量以及非集结系统对其演化的影响。由气泡引起的整体液体运动和液相的停留时间分布分析是通过使用感应传感器进行的。气体滞留结果表明，在距离气体分布器足够远的区域（II区）中，气体的存在更为重要。体积传质系数（K _L a）的结果表明，K _L a随着添加醇而降低，特别是当醇中碳的数量增加时。ķ_大号随着阴离子表面活性剂的添加，其下降更多。还证明了K _L a的降低归因于K _L的降低，这归因于气泡上升速度的降低以及当添加醇或离子表面活性剂时的扩散率的降低。建立了将气体滞留率和气液传质系数与表观气体速度和表面张力梯度联系起来的相关性。
