Polyethylene Terephthalate Production Process - Cost Analysis - PET E11A

Book excerpt: This report presents a cost analysis of Polyethylene Terephthalate (PET) production from ethylene glycol and purified terephthalic acid (PTA) The process examined is a typical melt-phase polymerization followed by solid-state polymerization. In this process, initially an oligomer intermediate is produced by the esterification of PTA with ethylene glycol. The oligomer then undergoes a melt-polymerization and a solid-state polymerization, leading to a bottle grade PET. This report was developed based essentially on the following reference(s): (1) "Polyesters, Thermoplastic", Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition (2) "Polyesters", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition Keywords: Thermoplastic Polymer, Polyester, High Intrinsic Viscosity, Melt-Phase Polycondensation
