In a lube base oil production,
the feed heavy neutral distillate is originated from fractionation of various
crude oil blends. Because the changing feed properties affect both yield and
quality of raffinate, the plant operating conditions need to be tuned
accordingly. In this study, a predictive model for an existing industrial-scale
extraction process dedicated to group-I production is constructed to determine
the right operating parameters in advance, which minimizes off-spec production
due to faster adaption of operation to a new feedstock. It is developed via use
of the phase equilibrium data published for heavy neutral distillate + Furfural
system, laboratory measurements of physical properties and composition of
distillate as well as the existing plant data. The accuracy of the
corresponding process model is increased via determining stage efficiency from
an empirical equation based on only selected operating conditions, namely
solvent temperature and solvent-to-distillate ratio.
