The Opportunity

PET (polyethylene terephthalate), one of the most commonly utilized resin products in the world, requires the chemical intermediate PTA (purified terephthalic acid).

 

The PTA manufacturing industry produces literally billions of gallons each year of wastewater containing lost resources such as PTA fines, cobalt catalyst and demineralized water. The wastewater is primarily produced in the purification of crude terephthalic acid. Conventional technologies cannot economically recover these valuable resources.

 

The Solution

To address the problem of a major PTA manufacturer's resource losses, MPT completed extensive process development activities, both at the customer's site and at MPT facilities. MPT utilized a combination of HyperFluxâ„¢ advanced membrane cross-flow filtration and HyperSorbâ„¢ sorption technologies to solve the resource recovery challenge. Through application of advanced inorganic membrane technology and special reactive polymers, recovery of lost PTA fines, cobalt catalyst and water was accomplished.

 

The Value

PTA, like many other commodity chemical products, is brought to market under the constraints of very tight margins. Process improvements continue to provide opportunities which can make a significant impact to the bottom line for the PTA manufacturer.

 

By outsourcing build/own/operate wastewater services to MPT, our PTA customer continues to experience significant resource recovery and bottom line benefits.
