Description of Recycle Base Oil
Recycle Base Oil is eco-friendly, and it generates lower carbon emissions than virgin base oil. The process of production of virgin base oil is energy intensive and it generates higher emissions of carbon. Rise in the focus on sustainability of the environment across the globe is providing significant opportunity to the global recycled base oil market.
Automotive oil recycling involves the recycling of used oils and the creation of new products from the recycled oils and includes the recycling of motor oil and hydraulic oil.
Oil recycling also benefits the environment. increased opportunities for consumers to recycle oil lessens the likelihood of used oil being dumped on lands and in waterways. For example, one gallon of motor oil dumped into waterways has the potential to pollute one million gallons of water.
Additionally, limited availability of feedstock required for the manufacture of virgin oil is driving the need for use of recycled base oil. Producing base oil from crude oil is an energy-intensive process.
A refinery needs to process 100 gallons of crude oil in order to produce one gallon of base oil. On the other hand, only 1.4 gallons of used oil is sufficient to manufacture one gallon of base oil. This makes recycling of used oil a fairly viable process for base oil manufacturing.
Pre-treatment or Dewatering
Pre-treatment of used oil involves removing any water within the oil, known as dewatering. One way of doing this is by placing it in large settling tanks, which separates the oil and water.
Further recycling steps include
Filtering & demineralization of the oil, to remove any solids, inorganic material and certain additives present in the oil, producing a cleaner burner fuel or feed oil for further refining.
Propane de-asphalting to remove the heavier bituminous fractions, producing re-refined base oil; and
Distillation to produce re-refined base oil suitable for use as a lubricant, hydraulic or transformer oil. This process is very similar to the process undergone by virgin oil.
Water is found in used oil as free water or bound water, for example in emulsions. The term dewatering is usually taken to mean the removal of free water. Where water has been emulsified with oil, the emulsion has to be “broken” with a demulsifies before the water can be separated from the oil.
Dewatering is a simple process relying on the separation of aqueous and oil phases over time under the influence of gravity. The used oil is allowed to stand in a tank (raw waste oil) and free water drops to the bottom where it can be drained, treated (wastewater treatment) and discharged appropriately to sewer or stormwater depending on quality and local regulations.
Uses of Recycle Base Oil
Recycling used oil keeps it from polluting soil and water.
Motor oil does not wear out—it just gets dirty—so recycling it saves a valuable resource.
Less energy is required to produce a gallon of re-refined base stock than a base stock from crude oil.
One gallon of used motor oil provides the same 2.5 quarts of lubricating oil as 42 gallons of crude oil.
Used oil includes a variety of origins such as:
- Motor oil
- Industrial oil
- Lubricating Greases
- Metal processing fluids
- Additives
- Hydraulic Oils
- Transformer Oils
Packing of Recycle Base Oil
Recycle Base oil packed in new or used 180 kg drums, iso tank, flexitanks, and IBC tank. Each 20-foot container takes 80 drums.
