• Short Path Distillation Process - Thin Film Evaporation
• Intermediate tank age
• Solvent extraction
• Solvent recovery and drying
• Product storage & Dispatch
The process uses vacuum distillation and tertiary product” polishing" by solvent extraction. These processes remove contaminants that mix with the oil in motor engines. In a process manufacturing context, the process uses only moderate temperatures and pressures (vacuum) to sequentially remove water, fuels and residue from the lubricant.
Initially the used oil would be chemically treated. The pre-treated oil would then be fed to a water evaporation unit and the temperature of the oil would be heated to 120-140°C. The water and entrained light ends would be thermally treated on site and the water vapor exhausted to atmosphere. The preheated and dried used oil would then proceed to the de-fueling stage. The de-fueling stage would be undertaken in a specially designed vessel where the temperature of the oil would increase to between 250-280°C under intermediate vacuum. Fuel (or gas oil) material would then be taken off to dedicated storage in the tank farm (for subsequent sale as an industrial fuel product) and the dried and de-fueled used oil would pass to the main distillation processes.
Short Path Distillation – Thin Film Evaporation:
Primary base oil recovery process would occur in a short path distillation–Thin Film Evaporation where the feed oil would be exposed to elevated temperatures of up to 350°C at high vacuum. The base oil would be distilled off for intermediate storage and the majority of the heavy base oil and heavier fractions would pass to the subsequent Short Path Distillation -Thin Film Evaporator. The distillation in the pressure range below 1 mbar requires large cross sections for the transport of vapors from the place of evaporation to the place of condensation. Too small cross sections inevitably lead to a higher pressure in the evaporator as this pressure is required for the transfer of vapors to the condenser. The required cross section cannot be reached if we have two separate apparatuses to perform the distillation process, one for evaporation (evaporator) and a second one for the condensation (condenser). Both functions - the evaporation and the condensation - have therefore to be realized in one apparatus only. Short Path Distillatory meets this requirement. They are equipped with vertically arranged cylindrical surfaces for the evaporation. The material to be distilled is being fed continuously onto this heated surface from the top and distributed evenly by means of a wiper system. It is flowing downward as a thin film. Depending on the temperature of the heated surface and the pressure in the apparatus the light volatile components of the feed material are evaporated. WFE ex cels in distillation steps where products are heat sensitive, viscous, tend to foul heated surfaces, or are high temperature boiling.
Following are the Silent Points in Agitated THIN FILM EVAPORATOR RE-REFINING OF USED LUBE OIL DESIGN BY OUR
CHEMICAL ENGINEERS TEAM.
Per Shift to Operate the Unit. Once started, it has to run Continuously 24 Hours a Day and Seven Days a Week till Feed Stock
(Used Oil) is exhausted.
Used/Waste Oil is Raw Material of Re-Refine Plant. The Used Oil is Available every part of the world at Garages, Service Stations, Ship Service Stations, and Industrial units.
RE-REFINING of the following oils can be done:
The Used Oil Contains Water, dirt, metal, solid particles from rust and other impurities.
