Abstract: The LUKOIL Neftohim Burgas (LNB) H-Oil hydrocracker performance at different operating conditions, and different crude oils, and processing of recycle of partially blended fuel oil (PBFO) was assessed. The lower throughput, a result from the Covid 19 pandemic, allowed the LNB H-Oil hydrocracker to operate at a capacity lower than 50% of the design and to process recycle of PBFO achieving a vacuum residue conversion of 93%. The impact of crude oil slate, and processing of recycle of PBFO on conversion and on the unconverted hydrocracked vacuum residue quality was discussed. Intercriteria analysis was employed to evaluate the statistically meaningful relations of the operating conditions to the H-Oil conversion and yields. Regression equations were developed and discussed. [Received: April 16, 2021; Accepted: 28, 2021]
