Deoiling process

A method of deoiling comprising:

• introducing a waxy feed and a deoiling solvent to a dilution chilling zone, the waxy feed comprising about 70 wt. % wax or more and an oil, as determined by ASTM D721;
• co-currently mixing the waxy feed and the deoiling solvent in the dilution chilling zone while agitating the waxy feed and the deoling solvent to form a slurry, wherein the agitation is sufficient to provide substantially instantaneous mixing of the waxy feed and the deoling solvent, wherein the deoiling solvent is added in an amount such that the slurry has a liquids:
• solids volume ratio of from about 10:1 to about 20:1, wherein a temperature of the solvent introduced into the dilution chilling zone is from about 10° F. (about −12° C.) to about 30° F. (about −1° C.);
• withdrawing the slurry from the dilution chilling zone and introducing the slurry to a filter zone while simultaneously co-currently mixing additional waxy feed and deoiling solvent in the dilution chilling zone, the filter zone comprising one or more filter stages, wherein a temperature of the slurry is from about 40° F. (about 4.5° C.) to about 75° F. (about 24° C.);
• separating the wax from the oil and the deoiling solvent, by filtering the oil from the wax, to form a wax cake in a first filter stage;
• and
• washing the wax cake in the first filter stage with the deoiling solvent by spraying the wax cake with the deoiling solvent to obtain a composition comprising a wax.
