Information @ a Glance

  • The lubricating oils used by vehicle engines have to be replaced at least every 20 000 km.

  • This oil used to be dumped, but now most of it is re-refined and reused. This is done in a three step process, in which water, solids, lighter oils, dissolved metals, degraded additives etc. are removed.

  • Three steps include: Dehydration, Diesel stripping, Lube oil distillation and condensation.

  • Solvent extraction has been known as one of the potential techniques for recycling used lubricating oil.

  • The solvents used were liquefied petroleum gas (LPG) condensate and stabilized condensate.

  • The extraction process using stabilized condensate demonstrated characteristics that make it competitive with existing used oil treatment technologies.

  • The main products of re-refining are diesel fuel, high and low quality lubricants and heavy fuel oils used in industrial burners.

  • The basic equipment costs of recycling used lubricating oil as a diesel fuel supplement are $8,500 to $10,000, and the total capital investment ranges from $57,000 to $80,000.

  • If the oil is re-refined into lubricating oil for vehicular use, a net savings of $1.50 per gallon could be realized.
