摘　　要：在１２０的不锈钢填料塔中，以１６共轭环塔填料为研究对象，分别选用正丁醇－丁二酸－水和３０％ＴＢＰ（磷酸三丁酯）的煤油－醋酸－水２种不同界面张力的体系进行试验，测定了该填料在不同两相流速下的表观传质单元高度，和相同条件下测定的同尺寸鲍尔环、拉西环和θ环作了比较，θ环的表观传质单元高度（Ｈｏｘｐ）比共轭环小，但共轭环的（Ｈｏｘｐ）分别比鲍尔环小１６％，比拉西环小２５％．本文对影响传质性能的因素也进行了分析．In a  120mm extraction column, two different extraction systems, butanol_succinic_water and 30%(TBP) kerosene_acetic acid_water are chosen to examine the mass transfer performance of  16 conjugate ring under various continuous phase and disperse phase velocities, and compared with that of same size rashing ring, pall ring and θ ring under the same conditions. Results show that H oxp (height of mass transfer unit based on plug flow and continuous flow) of conjugate ring is bigger than that of θ ring, but less than that of pall ring and rashing ring at a rate of 16% and 25% respectively. Factors of affecting mass transfer were discussed.
