Abstract: A study on two-phase How characteristics was carried out in two structured packed extraction columns of 40mm, 100mm in diameter with 30%TBP (inkerosene)/acetic acid/water and n-butanol/succinic acid/water as testing systems. Correlation of all experimental data gave the following flow equation for structured-packed extraction column: for 30% TBP(in kerosene)/acetic acid/water system, c =0.508, n =0.26 for n- butanol/succinic acid/water system, c =0.717, n =0.53

摘要： 在内径分别为40、100mm的板波填料萃取塔中,对30%TBP(煤油)-醋酸-水和正丁醇-丁二酸-水两种体系的流体力学特性进行了实验研究,并对实验数据进行分析处理,得到了描述板波填料萃取塔流体力学行为的关联式U_x/(e(1-φ))+U_y/(eφ)=c(a/eg·ρ_c/Δρ)~(-1/2)·(1-φ)~n
