What can old engine oil be used for?

Old engine oil is a kind of waste oil produced when people change the lubricating oil for engines and gears, etc. What can old engine oil be used for? Is it recyclable?

Actually, though no longer suitable for its original purpose directly in engines due to degradation and contamination, old engine oil can indeed be recycled and repurposed.

Old engine oil after use for recycling

As we know, the best way, also encouraged by the government, to manage various kinds of waste is through recycling, which can not only dispose of waste, but also benefit from the waste recycling process. The common old engine oil recycling way is waste oil distillation technology, designed for recycling the old engine oil and other similar waste oil, heavy oil, etc., from which the non-standard diesel and asphalt will be obtained.

Old engine oil/waste oil to diesel recycling distillation machine

1. Old engine oil recycling principle

For e.g. waste tyre and plastic are managed by recycling renewable energy--waste pyrolysis oil, And after further refinery, this pyrolysis oil can be refined into diesel-like fuel. Both waste pyrolysis oil and old engine oil belong to waste oil, and normally old engine oil has best quality among other kinds of waste oil, so to extract diesel-like fuel oil from old engine oil is of no question.

Old engine oil is very heavy, it has higher flash point and viscosity than diesel and waste tyre/plastic pyrolysis oil, so, if it is used directly for heating, the heat utilization efficiency is not high, besides there are large quantity of waste residues produced because of inadequate combustion. Therefore, before old engine oil is able to used for heating, it has to be refined into lighter diesel-like fuel with waste oil distillation machine.

Waste oils for recycling and distillation to diesel

2. Old engine oil recycling machine

Our new model waste oil distillation machine is specially designed to process old engine oil. The treatment process includes heating, cracking distillation, solid catalyst or liquid fuel refining, odor and color removal as well as oil color further removal. Welcome to click the operation video of waste oil distillation machine to learn the detailed working process:

The final oil got from old engine oil is pure non-standard diesel like fuel, oil standard can be close to China 0# diesel, which can be used as industrial heating energy for steel mill, ceramic factory, cement factory and brick factory, etc. And you can also use it in diesel generators, trucks, ships, boats, tractors, or other similar heavy machinery. Besides, the output yield of old engine oil to diesel is as high as 85%, so old engine oil is a very good waste oil used for recycling to get diesel like fuel. Besides the diesel, we can also obtain asphalt(bitumen) from old engine oil distillation machine, which can be a component in the production of asphalt for road construction, improving the binding properties and durability of the material.
