The Atmospheric and Vacuum Residue (AR/VR) hydrotreater is a key refinery unit which improves Residue Feeds for Fluid Catalytic Cracking (RFCC) units and which produces additional diesel as well as low sulfur fuel oil. Residue hydroDeSulfurization units (RDS) improve downstream conversion operations by eliminating difficult feed components thus enabling the refinery engineers to squeezing the most out of the bottom-of-the-barrel, and maximize profitability.
Axens' unique portfolio for AR/VRDS processing is highlighted by the Hyvahl™ technology and a full range of advanced resid hydrotreating catalysts.
Atmospheric residues (ARs), vacuum residues (VRs), and also refractory oils such as heavy deasphalted oils (DAOs), straight-run vacuum gas oils (VGOs), heavy coker gas oil (HCGO) or coal-derived oils such as coal slurries (Direct Coal Liquefaction, DCL), as well as PyOil from steam crackers are all potential H-Oil® feeds.
