Abstarct. This article is devoted to the experience of TAIF-NK JSC Refinery in the application of hydrogenation processes in the processing of heavy residues of oil distillation – Vacuum Residue. The complex of TAIF-NK JSC, which operates on the basis of Veba Combi Cracking (VCC) technology, is the only one in the world that allows processing of heavy residues (Vacuum Residue) obtained by primary distillation from crude oil, with maximum production of high-quality light oil products. Implementation of hydrocracking technology on the basis of VCC technology at TAIF-NK JSC ensured the achievement of oil refining depth and light product yields for 2021 — 85.1% and 80.7% respectively. The article demonstrates the retrospective dynamics of indicators of oil refining depth and light oil products draw-off from implementation of the project, the change in the food basket, as well as highlights the problems that arose in the course of implementation of the project.
