Dow, DPT Launch PTA Technology


Nov 11, 2010

The Dow Chemical Co. and Davy Process Technology (DPT) announce the launch of Compress PTA, a streamlined technology for the production of Purified Terephthalic Acid based on the breakthrough combination of demonstrated pressure filtration; solvent recovery and integrated water recycle processes. PTA production is integral to the manufacture of PET (polyethylene terephthalate); a performance polymer used in fiber, film, packaging containers, engineering resins and binder resins.
This new technology process is said to offer PTA producers an investment cost reduction of 15%, higher reliability leading to higher capacity utilization, and conversion cost improvement of 20% compared to competing technologies.
The technology is jointly licensed, with basic engineering being provided by DPT.
