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.

The report provides a comprehensive study of Polyethylene Terephthalate production and related Polyethylene Terephthalate production cost, covering three key aspects: a complete description of the Polyethylene Terephthalate production process examined; an in-depth analysis of the related Polyethylene Terephthalate plant capital cost (Capex); and an evaluation of the respective Polyethylene Terephthalate plant operating costs (Opex).

The Polyethylene Terephthalate production process description includes a block flow diagram (BFD), an overview of the industrial site installations, detailing both the process unit and the necessary infrastructure, process consumption figures and comprehensive process flow diagrams (PFD). The Polyethylene Terephthalate plant capital cost analysis breaks down the Capex by plant cost (i.e., ISBL, OSBL and Contingency); owner's cost; working capital; and costs incurred during industrial plant commissioning and start-up. The Polyethylene Terephthalate plant operating costs analysis covers operating expenses, including variable costs like raw materials and utilities, and fixed costs such as maintenance, labor, and depreciation.

Polyethylene Terephthalate Production Cost Report Process Schematic

The process under analysis comprises two major sections: (1) Melt-phase Polymerization; and (2) Solid-state Polymerization.

Melt-phase Polymerization. Terephtalic acid (PTA), ethylene glycol (MEG), and additives are mixed in the paste system and fed to three consecutive reactors: (1) esterification; (2) prepolymerization and (3) polycondensation. Water vapor formed and unreacted MEG are continuously removed and routed to MEG Recovery downstream. The resulting polymer is fed to a Pelletizing system, in which the molten PET is extruded, cooled, and then chopped into cylindrical shapes.

Solid-state Polymerization. The amorphous PET chips are directed to the Crystallization, where they are first submitted to a hot flow of nitrogen in order to prevent that PET chips stick together while the polymer moves through the glass transition temperature. The particles are then fed to the crystallizer itself, in which they achieve the minimum crystallinity to flow in the solid-state polycondensation (SSP) reactor, a long cylindrical hopper-type vessel, where high molecular weight polymer is formed. The PET product is further cooled, packed and stored.
