Description

The PET reaction trains use the technology from DuPont for TPA based esterification process and the upgrades to enhance the polymerization capacity. This technology includes six (6) process sections: PTA & MEG slurry mixing, esterification, catalyst and additive injection, pre-polymerization, polymerization, and ship formation. The pre-polymerization uses glycol enhanced mass transfer without mechanical agitation. The polymerization occurs by a cage-type finisher agitator without central shaft. Continuous wiping of finisher vessel wall eliminates degradation. The product bottle resin has polymer IV 0.6 (+/- 0.01), catalyst concentration less than 250 PPM as Sb, DEG content 1.2% in polymer, IPA 2.15% weight, toner (Cobalt Acetate) 60 PPM, phosphoric acid 20 PPM, COOH 40, acetaldehyde 90 PPM, moisture content 0.2%, bottle chip weight 15 – 18 mg/chip, chip size 3.0 X 2.0 X 2.5 mm. The SSP (Solid State Polymerization) plant uses UOP technology further processes the PET resin of 0.60 dl/g IV into 0.84 dl/g IV, which is bottle grade quality resin. The SSP process includes 4 steps: (1) crystallization, (2) annealing, (3) SSP reaction, (4) cooling.
