Feed from 1 optionally heated to 100-150‹ F. in heat exchanger 3 is introduced into dilution chilling tower 5 in which it is contacted with successive additions of solvent at -45‹ to 0‹ F. through lines 49. The pressure in 5 is such as to maintain the solvent in the liquid phase, and the mixture is agitated, e.g. by turbine or propeller and disc agitators. Oil-solvent mixture leaving 5 at from 0-40‹ F. is fed via drum 7 alternately to batch chillers 11. Cooling is effected by controlled evaporation of the solvent under the suction action of lines 12, 13, 14, 15, 21 and 40 to a propane compresser, additional wax being crystallized. At a pressure of about 1 atm. and a temperature -30‹ to -40‹ F. the slurry is withdrawn through 17, 18 to 1st filter drum 19. The filtrate passes to high and low pressive flash towers and then a vacuum "explosivity corrector" to remove solvent from the de-waxed oil. The wax residue is treated with further cold solvent under agitation and passed to second filter 43 where a filtrate of solvent containing 2-10% by wt. de-waxed oil, and a wax containing 0À1-5% by wt. oil is produced. Further filter stages are optional. The cold final-stage filtrate is recycled via line 48 and injection lines 49 to dilution chilling tower 5, and the final-stage wax is passed to a flash tower to remove solvent. The solvent may be propane or propylene (preferred), ethane, ethylene butane, butylene, or a mixture thereof.
