1. Problem Statement Benzene, toluene and xylene are important precursors in the manufacture of petrochemicals. The feedstock can be reformed naphtha. open fire --> News New Case You have been contracted to design the distillation column for the recovery of benzene. You may assume that a constant flow of 150 metric tonnes per hour of feedstock is to be processed. Typically, a column will have a feed stream pumped at a certain temperature and pressure, a vapour stream that is cooled by an overhead condenser, a reflux stream that is pumped back to the column by a reflux pump, and a reboiler that adds heat to the process. 2. Data Feed Composition: Benzene 0.75 0.22 0.01 Toluene p-xylene 0-xylene m-xylene 0.01 0.021 Temperature and Pressure You choose, but ensure that these parameters are suitable to comply with the client's Note that some of the materials may need to be in a liquid state and that the pressure a level that will cause the benzene to flash when it enters the column.
