A PROCESS FOR DISTILLING PARAFFINIC HYDROCARBONS COMPRISES FEEDING A FISCHER-TROPSCH DERIVED PARAFFINIC HYDROCARBON FEEDSTOCK COMPRISING HEAVY PARAFFINIC HYDROCARBONS AND, OPTIONALLY, LIGHT AND/OR MEDIUM PARAFFINIC HYDROCARBONS, INTO A DISTILLATION COLUMN (12). THE DISTILLATION COLUMN (12) IS OPERATED TO PRODUCE USABLE WAX PRODUCTS. AN OVERHEAD STREAM, A BOTTOM STREAM, AND AT LEAST ONE SIDE STREAM, ARE WITHDRAWN FROM THE DISTILLATION COLUMN (12). ALL THE WAX PRODUCTS OBTAINED ARE USABLE WAX PRODUCTS. (FIGURE 1)
