    Project Name:

  • Polyester Polymerization Lines , Polyester chip plant,Polyester production plant , Polycondensation plant (Polytex tech,Polytex Design)
  • Main Raw Material: PTA(Pure Terephthalic Acid) and MEG (Mono Ethylene Glycol) OR DMT(Dimethyl terephthalate) and MEG (Mono Ethylene Glycol)
    Project Description:

  • PET batch type,PTA or DMT based (BP)(Single line:2TPD~100TPD)
  • PET continuous polymerization,PTA based (CP)(Single line:20TPD~1000TPD)
  • Mult-Function continuous polymerization,PTA or DMT based (M-CP)(Single line:15TPD~300TPD)
    Polyester batch type (Polytex tech,Polytex Design) (Batch-poly Single line:2TPD~100TPD):
  • EG distribution system
  • Paste preparation system
  • Esterification system
  • Polycondensation system
  • Chip cutting and packing system
  • TiO2/SiO2 Preparation System
  • Filter cleaning system
  • EG recovery system
  • Other Additative (Including SIPE/SIPA)Preparation System
  • Thermal Fluid system
    Specification and Advantage:
  • Paste preparation system can be used for preparing material of modified PET, catalyst and additive can be fed in low temperature.
  • Esterification in the low-temperature normal temperature or under continuous feed, easy to control, safe and reliable
  • The Pre-poly reactor is for modified PET products. It's easy for changing product, and the reactor should not be cleaned to avoid the material waste caused by system start and stop. Pre-poly reaction can be finished to improve the product capacity.
  • EG vacuum system will not generate the waste water.

    Apply to Bright chips,Alkali-dissolved chips, CDP, Semi-dull, Full- dull, Antistatic, Anti-pilling, Far infrared, Antibiosis, Film grade, Bottle grade and other fields.
