Waste oil distillation equipment

Waste oil distillation and upgrading plant

A pretreatment, heating, fractionation and condensation line for waste engine oil, lubricants and pyrolysis oil.

Published models and values are references for early comparison. Final capacity, weight, power, shipment and configuration remain subject to confirmed technical documents.

Waste-oil distillation separates and recovers fractions by boiling range

  • Feedstock is settled, filtered and dehydrated before controlled heating. Vapour fractions are separated and condensed by boiling range, while heavy residue remains for separate handling.
  • Water, solids, viscosity, sulphur, flash point, boiling range and target specifications determine atmospheric or vacuum operation, tower configuration and condensation load.

Main outputs

  • Light fractions

    Lower-boiling fractions whose use requires testing.

  • Main distillate

    Assess quality against the intended fuel or base-oil route through sampling and testing.

  • Heavy residue

    A high-boiling stream that needs a defined use or disposal route.

  • Process gas

    Handled by the condensation and closed gas system.

Product and engineering features

  • Configure pretreatment, distillation, tower and condensation as one system
  • Compare atmospheric, vacuum and custom routes
  • Work backwards from target specifications
  • Use as a pyrolysis-oil upgrade or standalone waste-oil line

Frequently asked questions

  • Does every pyrolysis project need distillation?

    No. Compare oil analysis, buyer requirements, upgrading cost and additional environmental scope first.

  • Can distillate automatically be called diesel or base oil?

    No. It must meet the relevant specification and buyer testing requirements.

  • How are atmospheric and vacuum routes selected?

    Selection depends on boiling range, thermal sensitivity, target fractions, energy, operations and economics.

Selection basis

Design the distillation route backward from feedstock range and product specification

Used lubricants, industrial waste oils, tyre oil and plastic oil differ in water, light ends, ash, metals, sulfur, chlorine and thermal stability. Confirm feedstock tests and target fractions before selecting pretreatment, pressure, columns and condensation.

Segregated storage

Keep sources and batches separate to prevent uncontrolled quality variation.

Pretreatment

Settling, filtration, dehydration and solids removal influence stability and cleaning intervals.

Separation objective

Target boiling range, flash point, viscosity and use define column, pressure and receiving systems.

Residue and gas

Heavy residue, non-condensable gas and odour treatment belong in the complete project boundary.
