PREDICTION OF SOLUTE CONCENTRATION CHANGES ALONG PULSED SIEVE PLATE EXTRACTION COLUMNS

摘要

Pulsed columns are one of the most important extraction columns that have extensive application in different industries. Obtaining the solute concentration in different heights of the column has a great influence on achieving the physical property changes of the phases along the column. An experimental work of mass transfer in a pilot pulsed sieve plate extraction column at different operating conditions is carried out in this research, and the solute concentration in different heights of the column is obtained for two different systems with medium and high interfacial tensions. The solute concentration changes along the column are calculated using previous models in the literature and the model presented for achieving the effective diffusivity in a previous work of the present authors. Comparison of the experimental results and the models is made and the best one is suggested.View full textDownload full textKeywordsDiffusivity, Pulsed columns, Solute concentrationRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00986440902900758
