Abstract

In order to resolve the problem of controling the vapour split in the divided wall column (DWC)

a new vapour splitter was put forward. The study was carried out by using the computational fluid dynamics (CFD) software STAR-CCM+ with k-ε turbulence model and SIMPLE method. The split and the nonuniformity of the vapour were researched and compared against experimental data. The relationship between vapour tubes and internal diameter of the column was examined by simulations. Model results and experimental data obtained in this study have revealed that the device can accurately adjust the vapour split and achieve a uniform vapour distribution. The model results were in good agreement with experimental data.
