Description
Summary:HYSYS process modeling software was used to analyze the effect of reflux ratio and number of trays on the purity of ethylene in a vapor recompression distillation column and also in an ordinary distillation column. Analysis of data showed that with increased pressure a higher reflux ratio is needed to obtain a purity of 99.9{\%} for both towers. In addition number of trays was varied to see its effect on purity. Analysis proved that purity increases with number of trays.
