The paper presents results of an experimental study of separation efficiency and distribution of flow parameters over the cross section of the distillation columns. The experiments were carried out on the large-scale research setup “Large Freon Column” with diameter of packing of 0.6 m and 0.9 m. The mixture of refrigerants R114 and R21 was used as the working liquid at a pressure of 3 bar in the column. Experimental data were obtained at uniform and nonuniform irrigation of the Mellapak 350.Y and Sulzer 500X structured packings by a controlled liquid distributor. The liquid distributor with independently controlled valves for each drip point was used for controlled packing irrigation. The newmethod for dynamically controlled irrigation of the packing by an operated liquid distributor is suggested. This method is aimed at the destruction of large-scale maldistribution areas (flows) inside the column and the achievement of higher separation efficiency through periodic irrigation of the entire packing or its individual areas under the liquid distributor. The use of dynamically controlled irrigation of the packing allows an increase in efficiency of mixture separation of up to 20%.

动态控制灌溉方式下结构性填料蒸馏塔混合气分离效率

本文介绍了在蒸馏塔横截面上分离效率和流动参数分布的实验研究结果。实验是在大型研究装置“大型氟利昂柱”上进行的，填料直径分别为0.6 m和0.9 m。在塔中以3巴的压力将制冷剂R114和R21的混合物用作工作液体。实验数据是通过受控的液体分配器对Mellapak 350.Y和Sulzer 500X结构填料进行均匀和非均匀灌溉而获得的。每个滴点均具有独立控制阀的液体分配器用于受控填料灌溉。提出了通过操作的液体分配器动态控制填料冲洗的新方法。此方法旨在通过定期冲洗整个填料或其液体分配器下方的各个区域来破坏色谱柱内部的大规模不均匀分布区域（流），并提高分离效率。使用填料的动态控制冲洗可以使混合物分离效率提高多达20％。
