Application of Ebullated-Bed Vacuum Residue Hydrocracking at Lukoil Neftohim Burgas

This paper summarizes the experience gained over seven years of operating an H-Oil ebullated-bed vacuum residue hydrocracking unit. The following key factors in improving performance process were identified, including feedstock quality, catalyst condition, as well loading and utilization unconverted residue. optimum combination these four allowed a conversion rate about 90% to be achieved. challenge still remains determine optimal approaches using produced at higher rates.
