CONDUX has completed a multiclient study specifying the capital investment and factory processing required to convert a large continuous PET manufacturing line for PTT production.
PTT is a new polyester composed of propanediol (PDO) and terephthalic acid (TPA). While PTT has been known for years, a potential economical process for producing polymerization quality PDO has recently been suggested by Shell Chemical. As a result, there is significant global commercial interest both in the manufacture of PDO and PTT.
PDO (1,3 propanediol) (complete)
Unlike TPA or DMT, the global capacity for PDO is too small to support growth in PTT. Thus, prospective producers are exploring different routes to the manufacture of PDO. The study compares several approaches. The cost of PDO is a critical issue.

PTT (3GT) (complete)
As the annual global capacity for PET is about 45 billion pounds and profitability is marginal, CONDUX projects that PET lines are likely to be converted to produce PTT as the demand grows. The issue is the cost of conversion.
