A renewable diesel unit at the Navajo refinery, in Artesia, New Mexico, completed in 2022 alongside a Pre-treatment Unit (PTU).

The PTU provides feedstock flexibility, mitigating single feedstock risk and generating value through the use of lower priced unrefined soybean oil and lower carbon intensity waste feedstock such as animal fats and distillers corn oil.

The 9,000 barrels-per-day renewable diesel unit upgrades the renewable feedstock refined by the PTU into a hydrocarbon, high-value renewable diesel that has 50% to 80% less net greenhouse gas emissions and is chemically equivalent to petroleum diesel.
