Abstract

The article focuses on a case showing the significance of staged modifications in improving benzene-toluene-xylene (BTX) extractive distillation unit capacity. In February 2000, a BTX extractive distillation unit was commissioned by an Asian petrochemical producer. In May 2000, the unit was shut down for tray replacement. After performing a test run in July 2000, modifications have been made which allowed the plant to meet design criteria.
