Thin Film Distillation Plant

Reclaiming Used Engine Oil

Teaming with international reputed company and professionals with over 30 years of experience in Waste Oil Continuous Distillation Process, ES offers new range of innovation process design in oil reclamation.

Ever thinking of reclaim the used engine oil to diesel and base oil?

ES make it possible with the input of latest technology as below

Our designs separate into two systems:-
a) Agitated Thin Film Evaporator (ATFE)+ Short Path Distillation Unit (SPDU)
b) Reactivated Oil Polishing Plant

Evolution of Distillation Process

Distillation is one of the most important thermal separation methods used in crude oil processing and separation as well as waste oil reclamation.

Below are the technology trend

Thin Film Distillation substantially reduce the boiling temperature of the oil in vacuum as compare to Pot still Distillation, thus reduce the process energy cost. It also allows thermal separation of products effectively, as compare to Pot Still Distillation would destroy the oil due to high temperatures and long residence time.

In a Thin Film Evaporator the raw material is heated up on the internal surface of a heated tube until the lower boiling component starts to evaporate. These vapors are then liquefied on the cold tubes of a condenser. In Thin Film Evaporator design the condenser is located outside but as close to the evaporator as possible. Residence time in Thin Film and Short Path Evaporators is only few seconds, which helps to avoid thermal decomposition of the product. Thin Film Distillation is a continuous and single pass technology where not require to process for multi passes

The Improved Version:- Thin Film + Short Path Distillation (ATFE+SPDU)

Advantages of Thin Film+ Short Path Distillation

Positioning the condenser within the evaporator allows a further reduction of operational pressure down to vacuum 0.001 mbar as compare to 1 mbar in thin film evaporators. The stronger vacuum further reduce the temperature for oil boiling and avoid the issue of thermal decomposition. This is due to the fact that a pressure gradient from evaporator to condenser essentially can be avoided. Vaporized particles have a realistic chance to directly arrive at the condenser without colliding with other particles.

The geometrical distance between the evaporator and the condenser is in the range of few centimeters which is comparable with the mean free path lengths in this pressure range.

The unique combination of agitated thin film evaporator and short path distillation unit (ATFE+SPDU) to process used motor/mineral oils can maximize both the purity and distillation rate at lower energy cost per litre output


  • High Turbulence in a Thin /Wiped Film for High Mass and Heat Transfer
  • Short Residence Time for Low Thermal Stress of the Products
  • Evaporation in One Pass , No Circulation
  • Small Film Thickness, No Hydrostatic Height
  • No Product Fouling on the Heated Evaporator Wall Due to High Turbulence of Wiped Film
  • High Turndown Ratio, High Flexibility for Variation in Requirements
  • Distillation of High Viscosity Products by Special Designed Wiper Systems
  • Low operating pressure (Vacuum) Down to One Micron to Decrease Boiling Temperature
  • Reactivated Oil Polishing Plant

    In extension to the distillation output of base oil, ES offer of Reactivated Oil Polishing plant which is another innovation from oil regeneration process, this will further improve the quality of oil by improving oil colour and reducing acidity and absorbing fine impurity. The advantage of this process is the raw material, activated clay used for the polishing process can be reactivated over 300 times. This has substantially increase the life span of the activated clay from originally 1 weeks to 2 years

    This give a lot saving in terms of

  • Weekly replacement cost of activated clay
  • Weekly disposal cost for the used activated clay
  • 5-8% of oil loss when replacing the new clay due to absorption
  • Weekly down time due to the material changes

  • All the above costing is saved to occurrence only once in 2 years with the Reactivated Oil Polishing Plant. With the input of this technology, the process cost per litre of base oil output become very low and resulting the ROI for the investment become viable and short.

  • Process Flow of Single Base Oil output design ( ATFE+SPDU) for Waste Engine /Mineral oil Reclamation

  • Estimation of Output

    The output from the process may be varies depend on the source of oil

    Options of design and selections:
    Capacity: Range from 500 litre per hours 10000 litre/ hours output

    Operation/Control method:-
    Manual control, Semi Auto or Fully Auto by PLC and SCADA system

    Single base oil output or separate to 2 types:- low viscosity output and high viscosity output oil.

    Design and delivery:-
    System will be built in modular design so that it can be easily transport and assemble at site

    Modular design that can be easily assemble in the site.
