Reducing Material Waste in Flexible Pet (Polyethylene Terephthalate) Production

Siemens Process Control Application Note

Polyester is very popular because it is a light, soft, flexible, low-maintenance material that keeps you warm. Making it this way poses diverse challenges to PET producers.

A chemical plant specializing in producing PET was looking for a solution to reduce the waste resulting from product variance. The factory produces 25,000 tons of polyester annually, which is then provided to other manufacturers to produce a vast range of end products.

This vast range requires different PET grades, which are achieved by slight variations in the synthesis procedures. In order to investigate possible options to upgrade their primary processing, understanding the complete process is vital. In the case of PET production, this process starts with mixing three key ingredients – PTA and IPA powder along with glycol liquid – in specific ratios to make a paste.
