ABSTRACT

Effect of upward two-phase gas-liquid flow on the rate of liquid-solid mass transfer in a bubble column equipped with a horizontal tube bundle was studied by measuring the rate of the diffusion-controlled dissolution of copper in an acidified K₂Cr₂O solution. Variables studied included gas (nitrogen) flow rate, liquid flow rate, and the number of tube arrays. Data were successfully correlated by a dimensionless equation. The presence of surfactants reduced the rate of mass transfer by 3–17% depending on flow rates. The importance of the tube array as a built-in heat exchanger and a catalyst support was highlighted.

具有管束内件的泡罩塔反应器中的固液传质

摘要

通过测量铜在酸化 K ₂ Cr ₂中的扩散控制溶解速率，研究了向上两相气液流动对配备水平管束的泡罩塔中液固传质速率的影响哦解决方案。研究的变量包括气体（氮气）流速、液体流速和管阵列的数量。数据通过无量纲方程成功关联。取决于流速，表面活性剂的存在使传质速率降低了 3-17%。强调了管阵列作为内置热交换器和催化剂载体的重要性。
