Invista says it is confident of China's demand growth for nylon as the US-based fibre producer makes advancements in its 400,000 tonne adiponitrile (ADN) plant in Shanghai.

The US$1.2bn facility, announced in August 2018, is part of a deal with Shanghai Chemical Industry Park (SCIP). It will produce ADN – a key ingredient for the nylon 6,6 polymer used in plastics, coatings and apparel fibres.

In January, the project obtained Environmental Impact Assessment (EIA) approval and Safety Condition Review approval. Detailed engineering and procurement on the project are well underway, Invista says, with awards already made for more than 90% of process equipment. Construction is expected to start this year, with production scheduled for 2022.

"We are confident about China's demand growth and continue to advance our investment at SCIP," says Kyle Redinger, vice president Invista Intermediates Asia Pacific. "By our estimates, China could be the world's largest consumer of nylon 6,6 in the next few years, and we believe it's important to serve China from China to realise the full growth potential. We will continue our efforts to satisfy the strong local and regional demand for high-quality nylon products."

When complete, Invista's new ADN plant will integrate with its existing HMD and polymer facilities to directly supply domestic customers with the key building blocks to produce nylon 6,6 and other high-value products in China and throughout the Asia Pacific region.

Invista says its latest ADN technology brings improved product yields, reduced energy consumption, lower greenhouse gas emissions, enhanced process stability, and reduced capital intensity compared to existing technologies.
