中文摘要：

引言 20世纪70年代以来，填料塔已广泛地应用于精馏、吸收、解吸和萃取等工业分离过程．板波纹规整填料出现以后，与板式塔相比，在相同的分离效率下填料塔具有更低的压降、更大处理能力和更小持液量等优点，大大地扩展了其应用范围，在常、减压操作中有不少成功的例子．许多研究者也对这些条件下的填料分离和流体力学性能作了研究．但由于在高压下，气液相体积比以及体系密度、表面张力等物理性质的变化，其传质和流体力学行为都不同于常压．在高压条件下，规整填料压降小、处理能力大的优势已经不再明显，反之，其分离效率因返混的加剧而下降．

英文摘要：

The performance of wire gauze structured packing was studied in a packed column of 19 mm internal diameter under the condition of total reflux and high pressure. The pressure ranged from 0.7 MPa to 1.9 MPa. i-Butane/n butane was used as the testing system. The influence of pressure on HETP was investigated. With the increase of F-factor, the HETP values would slightly decrease at all testing pressure before flooding point. By comparing with the previous experimental data at Tianjin University, it was found that the separation efficiency of wire gauze packing was obviously higher than Mellapak 250Y structured packing.
