The Honeywell UOP Parex TM Process: Fifty Years of Growth for the Petrochemical Industry (Case Study)

Chapter 13 describes the genesis of competitive adsorptive separation of xylene isomers and how this led to the first application of the Parex process in 1971, the world's first commercial-scale adsorptive separation process for purifying and recovering para -xylene. The chapter goes on to highlight the advances in Parex technology that have been made over the years, resulting in its use in more than 70% of the world's para -xylene production for fiber, resin, and film applications.
