Abstract

Rectification is the most often used fluid separation technology. The improvement of the distillation equipment and process is significant because rectification has relatively low energy efficiency. The different constructions of the divided wall column (DWC) were investigated with simulation experiments. The structure of the column was implemented in Aspen Plus simulator using the Radfrac unit of the software. The column was divided in four parts, which were implemented with different blocks. The heat transfer between the feed and product zone was also calculated. The user interface of the simulation was then created. The optimal parameter combination of the DWC was determined. This construction was compared with column with sidestream product, which could solve the separation task. In this case, DWC was better than customary construction. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and the 19th International Congress of Chemical and Process Engineering CHISA (Prague, Czech Republic 8/28/2010-9/1/2010).
