Technologies (IntegRex®)

IntegRex® is Alpek’s proprietary technology for producing >Purified terephthalic acid (PTA)< and Polyethylene Terephthalate (PET) from paraxylene (PX) and monoethylene glycol (MEG).

IntegRex® uses the most advanced techniques to simplify the production process, from Paraxylene (Px) feeding to the production of PET. Based on innovation, integration and optimization of the different stages, this break-through technology has provided Alpek with significant savings in both capital investment and conversion costs.

The significant reduction in operating costs and capital, together with the near elimination of residual water, contributes to sustainability and environmental well-being.
