PROCESS DESCRIPTION
This unit is designed to catalytically saturate aromatic low viscosity index (LVI) lube oils and upgrade them to medium viscosity index (MVI) quality. The process facilities are similar to that of existing hydrotreaters but operate as a significantly higher pressure. The process design is set to run three distillates in blocked out operation. These are MVI 65, MVI 200 and MVI 750. Unit feed rates for the 3 distillates are as follows - MVI 65 - 8000 B/SD; MVI 200 - 6640 B/SD; MVI 750 - 3360 B/SD.
