Stamicarbon to license urea to DEF plant
Written by Richard Hands
Nextchem, through its nitrogen technology licensing arm Stamicarbon, has been awarded a licensing and process design package contract by AdvanSix for a new urea-to-diesel exhaust fluid (DEF) plant in Hopewell, Virginia.
The project scope includes a 700 st/d nameplate urea melt plant based on NX STAMI™ Urea technology, fully integrated with a DEF production designed to convert 100% of the urea melt into DEF. This configuration represents an innovative application for Stamicarbon, marking the first project in which all urea melt production may be dedicated exclusively to DEF.
