Effects of recycle type on solvent extraction through a parallel-plate membrane module

The effects of recycle type on membrane extraction through a parallel-plate module has been studied. Theoretical predictions are in fairly good agreem ent with the experimental results. Considerable improvement in mass-transfe r is obtainable if membrane extraction is operated with recycle which provi des the effects of pre-extraction and increasing fluid velocity. The influe nces of recycle type on the performance of membrane extraction, as well as on the fixed and operating costs, have been also discussed. (C) 2001 Elsevi er Science B.V. All rights reserved.
