Monday, November 14, 2022 - 1:20pm to 1:45pm
In this study, a modified Oldershaw column was installed and commissioned that is capable of operating under total as well as non-total reflux modes of operation. Furthermore, the Oldershaw column was validated with cyclohexane/n-heptane test system. Additional test systems were carefully selected to ensure that large VLE errors are avoided. The test systems also provided a wide variation in physical properties for the measurement of distillation column efficiencies. The effect of stripping factor on distillation column efficiency was studied by systematically varying the stripping factor for several test systems. The point efficiencies of the column under non-total reflux were compared with the results of our previous study under total reflux conditions. This paper will discuss important findings from the study.
