Mass Transfer Studies In A 'Finpak' Distillation Column

This thesis presents the results of an investigation of the behaviour of a new form of rectification device under vacuum distillation conditions.<br/><br/>The operating conditions were so varied as to not only provide a measure of 'Finpak' column efficiency under a variety of such conditions, but also to illustrate the effect such variables have on the overall distillation efficiency.<br/><br/>The results of the research indicate that the 'Finpak' fractionating column is a suitable contacting device for the investigation of mass transfer processes inhere low liquid rates are employed, such as in vacuum distillation.<br/><br/>With regards to the vacuum distillation process it was shown that column efficiency improved on reducing stillhead pressure, and it is proposed that the increase in efficiency occurs as a result of a reduction in the resistance to mass transfer within the liquid film, which may be as high as 9O % of the total resistance to mass transfer under the low liquid flow conditions employed throughout the study.
