It presents the economics of Polyethylene Terephthalate (PET) production from ethylene glycol and purified terephthalic acid (PTA) in the USA. The process examined in this report is a melt-phase process and solid-state polymerization similar to Invista NG3.
This report presents the economics of Polyethylene Terephthalate (PET) production from ethylene glycol and purified terephthalic acid (PTA) in the United States, via a typical melt-phase process followed by a solid-state polymerization. Initially, oligomers are produced by the esterification of PTA with ethylene glycol. The oligomer then undergoes a melt-polymerization and a solid-state polymerization, yielding PET.
