The #25 teller rosette (TR) random packing was used to enhance foam drainage in foam fractionation under continuous steady-state conditions and tested using sodium dodecyl sulfate (SDS) as a model surfactant. A column without the #25 TR served as control. The results demonstrated that the #25 TR was capable of enhancing the foam drainage and enrichment ratio while reducing the liquid holdup. The experiment was set up with optimized feed flow rate, liquid pool height, air flow rate, and SDS feed concentration. The enrichment ratio obtained by the #25 TR column was 1.76 times higher compared with the control column. Based on the mass balances and equilibrium relationship, a new method for graphical illustration of theoretical stages is also presented.

连续泡沫分馏中的随机堆积性能
#25 Teller Rosette (TR) 无规填料用于在连续稳态条件下增强泡沫分馏中的泡沫排放，并使用十二烷基硫酸钠 (SDS) 作为模型表面活性剂进行测试。没有#25 TR 的色谱柱用作对照。结果表明，#25 TR 能够提高泡沫排水和富集率，同时降低液体滞留率。实验设置为优化进料流速、液池高度、空气流速和 SDS 进料浓度。由#25 TR 列获得的富集率比对照列高 1.76 倍。基于质量平衡和平衡关系，还提出了一种新的理论阶段图解方法。
