A lubricant feed can be introduced into a vacuum distillation tower having a reduced pressure and a reduced or minimized water vapor par- 138 tial pressure. The lubricant feed can be separated into a plurality of lubricant boiling range products. The can allow an overlap in boiling ranges of one or more products separated from the lub- ricant feed to be reduced or minimized .132 —122 114 r 140 WO 2017/172311 Al 1#11101M01101010IIMME311111111111111111111111111111111110111111111111 SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
