What specific technology and scope of services is Axens providing to YPF for the diesel hydrotreating unit in Plaza Huincul?

Axens is providing YPF with a license for its Prime-D technology, basic engineering design, specialized equipment—including reactor internals, catalysts, and patented equipment—as well as technical support services such as catalyst loading guidance and technical training, for a 5,000 m³/day diesel hydrotreating unit at YPF’s Plaza Huincul refinery in Neuquén Province.

Why is YPF installing this new diesel hydrotreating unit, and what regulatory requirement does it address?

YPF is installing the new diesel hydrotreating unit to produce ultra-low-sulfur diesel in compliance with Argentina’s tightened national diesel sulfur limit of 10 ppm, which took effect in 2026; the project is a key measure to upgrade fuel quality and meet increasingly stringent regional clean fuel standards.
