Abstract: Polyester (PET) industrial production has been arrogant, the biggest use is processed into polyester fibers, at present, countries around the world the technology used in PET production line, there are mainly three kinds, namely, law DMT, PTA Act, EO of this paper focuses on the PTA Act Synthesis of PET, the study of its principles, introduced a polyester plant in Zhejiang Huatesi and the main production processes. Installation of direct esterification, continuous polycondensation of polyester production process, purified terephthalic acid (PTA) and ethylene glycol (EG) as raw materials and titanium dioxide (TiO2) for the extinction agent to ethylene glycol Antimony (Sb2(OCH2CH2O)3) as a catalyst, producing polyethylene terephthalate (PET).Study of its main production process, raw materials transportation, preparation and pulp preparation, esterification system, pre-condensation reaction system, final polycondensation reaction systems, transportation and melt granulation packaging. And to explore the esterification and polycondensation reaction of factors such as slurry ratio, yield, and so on.
