US chemical and fertilizer producer AdvanSix is exploring adding diesel exhaust fluid (DEF) production at its facility in Hopewell, Virginia, the company said today.
The location of the plant would position the DEF output to serve the US mid-Atlantic and Northeast, a region that is typically dependent on imports to keep the market in balance.
AdvanSix has partnered with nitrogen technology company Nextchem for the process design and licensing technology for the proposed expansion.
The project will move through detailed engineering and development phases before a final decision on the expansion is made, which is anticipated in the first half of 2027. Upon approval, the plant is anticipated to start up in 2029, AdvanSix said.
