The new technology, Invista’s most advanced adiponitrile, or ADN, technology, has already been deployed and proven at Invista’s facility in Orange, Texas, and now the company will implement it at the Butachimie joint venture facility in France. Butachimie is the largest ADN facility in the world. Invista’s new technology will be implemented by retrofitting the existing facilities during a planned turnaround in the second quarter of 2019.
ADN technology is used for the hydrocyanation of butadiene using a homogeneous nickel catalyst. ADN is a critical intermediate in the production of hexamethylene diamine, which is reacted with adipic acid to produce nylon 6,6. The update extends the company’s ADN technology in several aspects, including improved product yields, reduced energy consumption, lower greenhouse gas emissions, enhanced process stability and reduced capital intensity, compared to existing technologies.
“The performance of this technology at Orange has exceeded our expectations and we look forward to the benefits that deployment at additional facilities will bring to the marketplace,” said Bill Greenfield, president of Invista Intermediates. “Since beginning commercial operation of this technology in 2014, we’ve demonstrated improved yield, reliability and record production rates at Orange.”
Invista, based in Wichita, Kansas, will also implement its latest-generation ADN technology at its nylon intermediates facility in Victoria, Texas, pending final internal and regulatory approvals. Implementation is scheduled for the fourth quarter of 2020.
“We expect the combined increase in production capacity from deploying our technology in these existing facilities will be similar to that of a new ADN plant,” Greenfield said. “These considerable investments highlight Invista’s dedication to the nylon 6,6 industry and positions Invista and its customers with an advantaged and sustainable value chain.”
In China, the company has received strong interest from customers and others in the value chain seeking to participate with Invista in building a new ADN plant at the Shanghai Chemical Industry Park, where Invista opened a 215,000-ton hexamethylene diamine (HMD) plant and a 150,000-ton polymer plant in 2016. The company is assessing this approach.
As the preferred supplier for ADN, Invista supports growth and innovation in the nylon industry by continually investing in research and development, including the continued improvement of its ADN technology. The new ADN technology is the result of more than $40 million in research and development spanning four years on two continents.
With brands like Lycra, Coolmax, Cordura, Stainmaster and Antron, INVISTA is one of the world’s largest integrated producers of chemical intermediates, polymers and fibers. The company’s advantaged technologies for nylon, spandex and polyester are used to produce such products as clothing, carpets and air bags.
