Abstract

The KM–2 unit for production of oils and waxes has been operating at Slavneft'–Yaroslavnefteorgsintez Co. since 1984. It includes the S–200 section for deasphalting of vacuum resid obtained in vacuum distillation of atmospheric resid. The problem of increasing the output of this section has arisen with the increase in the demand for residual base oil.
