ABSTRACT
SARA composition and other characteristics of vacuum distillates from different crude distillation units are studied. It is established that all the distillates have broad boiling range. The distillates SARA composition was compared with the main viscosity-temperature characteristic of lubes, that is viscosity index. It was determined that, when utilizing the mentioned distillates to produce fuels, flow charts including purification the distillates from sulfur compounds are preferential. At the same time, when utilizing the mentioned distillates for production of lubes, which meet API specifications, more sharp fractionation at the first step with further hydrogenation processing within a general flow chart of lube production are required.
