碩士 === 淡江大學 === 化學工程學系 === 84 === The effect of recycle on the separation efficiency of solvent
extraction in aflat-plate microporous membrane module has
been investigated both theo-retically and experimentally. It
was found that with the recycle mo-dule design , the
flow rate of fluid in the system was increased andthe
overall mass transfer rate was thus augmented. Further ,
the con-centration of the aqueous solution at the
inlet was diluted due tothe effect of recycle , leading
to improved separation. Considerableimprovement in
separation was obtained with the use of recycle,
especially under the high reflux ratio. Experiments
for solventextraction of acetic acid from aqueous
solution by means of methylisobutyl ketone were carried
out in a flat-plate microporousmembrane module
both with and without recycle. It was found thatthe
overall mass transfer coefficient increases scarcely
with theflow rate of aqueous solution.
Experimental data for the overallmass transfer rate are
slightly higher than those from theoreticalpredictions.
