Abstract: A study on mass transfer performance was carried out in structured-packed extraction columns of 40mm, 100mm in diameter with 30% TBP(in kerosene)/ acetic acid/water and n-butanol/succinic acid/water as testing systems. The parameters of mass transfer and axial mixing were simultaneously estimated from a diffusion model by fitting the measured concentration profiles under steady state with optimization method.

摘要： 本文应用扩散模型并采用最优化方法拟合实测的稳态浓度剖面,在内径40mm、100mm的板波填料萃取塔中,用30%TBP(煤油)-醋酸-水和正丁醇-丁二酸-水两种体系研究了板波填料萃取塔的传质性能.
