Dividing wall column application for platformate splitter – A case study

摘要

This paper presents results of a simulation study indicating that a DWC would be arnbeneficial alternative to conventional two columns in series configuration for arnplatformate splitter application in a petroleum refinery. The DWC was designed usingrncommercial software, complemented by a fundamentally sound shortcut methodrnproposed by Halvorsen et al. [1-3] which allows generation of reliable initial values forrnrigorous simulations. Compared to actual, two-columns-in-series configuration, a DWCrnrequires approximately 33.6 % less energy to deliver three fractions at required productrnspecifications.
