Bottom of The Barrel
Axens offers an extensive line of residue and heavy-fraction conversion technologies. Our residue fluidized catalytic cracking (R2R) technology is a cornerstone for gasoline production.
For hydroprocessing residues Axens proposes both ebullated bed technologies (H-OilRC, H-OilDC) and fixed bed technology (Hyvahl) that can be combined with solvent deasphalting (Solvahl). In vacuum distillate hydrocracking, Axens is among the few licensors able to provide a large range of solutions ranging from mild hydrocracking to high-conversion hydrocracking (HyK).
Except for the high-conversion hydrocracking process, streams issued from bottom-of-the-barrel conversion require further processing before incorporation in ultra-clean fuel pools. For that purpose we successfully developed and commercialized our Prime-G+ technology that selectively desulfurizes cracked gasoline fractions. For diesel fractions issued from mild hydrocracking (HyC-10) and H-OilRC processes, Axens offers integrated diesel hydrotreating solutions.
