Invista Nylon Chemicals (China) Co. has begun construction on its new adiponitrile (ADN) facility at the Shanghai Chemical Industry Park (SCIP) in Shanghai, China. The project, costing over USD 1-billion, involves a 400 kta ADN plant based on Invista's "most-advanced, energy-efficient" ADN technology. Start-up is expected in 2022. When complete, the unit will be integrated with Invista's existing hexamethylene diamine (HMD) plant and polymer facilities to directly supply domestic customers. Invista currently has a 215 kta HMD facility and a 150 kta nylon 6,6 plant at the site.
