摘要

以30%TBP(煤油)-HNO_3-H_2O为实验体系

在外柱内径为100mm的环形脉冲萃取柱中以4种不同隙径比进行了传质性能研究.实验测定了环形柱的稳态浓度剖面

以扩散模型为基础拟合求取了传质模型参数

建立了相应的关联式.研究结果表明

4种不同隙径比环形柱的“真实”传质单元高度H_(ox)值可以用相同关联式表述;分散单元高度H_(oxd)值则与隙径比的0.16次方成正比.与外柱内径为50mm的环形柱相比较

其H_(ox)值可采用相同关联式描述;其H_(oxd)值与环形柱外柱内径有关.这反映了外柱径对环形柱轴向混合的影响.

Abstract

The mass transfer characteristics in an annular pulsed extraction column were studied with four different annular widths. 30% TBP(in kerosene)-HNO3 - H2O was used as experimental system (water as continuous phase). The solute concentration profiles under steady state were measured. Mass transfer parameters were estimated from the diffusion model by fitting the measured concentration profiles. Correlation of mass transfer parameters (Hoxand Hoxd) was suggested. Results showed that the "true" mass transfer unit height Hox of four annular extraction columns can be correlated with the same equation and the diffusion unit height Hoxd is in direct proportion to the 0. 16 power of the ratio of annular width to column diameter. In comparison with annular column 0. 05m in diameter

the correlation equation of Hox is the same for two kinds of annular column

but that of Hoxd is different. It indicates that axial miximg is affected by column diameter.
