Novel Approaches to Controlling Contaminant Levels in Vacuum Gas Oil (VGO)

摘要

THE IMPORTANCE OF CONTROLLING CONTAMINANT LEVELS IN VGO For many refiners, the amount of VGO that their vacuum distillation units {VDU) can generate is a critical constraint. Have you ever tried to lift more from the vacuum residue (VR) in order to fiii the hydrocracker, fluidised catalytic cracker (FCC) or other conversion unit, only for that downstream unit to suffer reliability issues as a consequence? When lifting additional VGO with standard hardware, elevated levels of metals and other harmful contaminants can be entrained in the VGO, However, with the latest technology it is possible to increase the VGO yield of a VDU substantially, at low cost, and without affecting the downstream units' reliability.
