What is the difference between oil recycling and oil refining

In daily life, tens of thousands of waste oils are constantly produced every day. This waste oil needs to be treated before it can be used in cars again. This not only protects the environment, but also saves costs. So now we all know that there are several ways to recover used oil. The first is an oil recycling method, which uses oil recycling plant to process waste oil to obtain a clean base oil. The second method is the oil refining method, that is, using oil refining equipment to perform a series of treatments on waste oil to obtain a base oil that can be reused. In addition, some refining equipment also has re-refining technology, so that the quality of the recovered oil is better and meets the use standards. So what is the main difference between oil recycling and oil refining?

Oil Recycling – Used Oil Filtered for Further Use

Recycled oil is used oil that has been run through a process of oil recycling that removes particulate and insoluble impurities. Although oil recycling process removes physical impurities in the form of particulate matter from the oil, it does not remove chemical impurities and contaminants. This allows the oil to be reused in the form of fuel or as lubrication in non-critical systems. Recycled oil is generally one-time-use and is not high enough in purity to be used in cars or trucks. Motor oils and hydraulic oils are commonly recycled and can be combusted as fuel for a variety of heating applications such as for boilers, space heaters and for industrial purposes such as for cement kilns or blast furnaces. Recycled motor oil can also be distilled into diesel fuel or marine fuel. Motor oil retains its lubrication ability and properties ongoingly and can be recycled again and again for a wide variety of different purposes. For this reason, recycled oil is positive for the environment, keeping lubricant products within circulation rather than being wasted through disposal or through environmentally detrimental dumping into soil or waterways.

Oil Refinery – The Removal of Soluble and Insoluble Impurities

Unlike recycled oil, where only soluble impurities such as heavy metals and dirt are removed. The oil refining system includes extensive processing, filtration, distillation and dehydration to remove both soluble and insoluble contaminants.

When the workers are finishing used oil refining process, additives are removed through chemical processing, which creates an un-additized base oil that can then be distilled to remove any remaining water or additional impurities. A dehydrating process removes residual light fuel, ethylene glycol, and a vacuum distillation step removes the fraction of oil suitable for reuse as lubricating oil. This fraction of oil undergoes hydro treating that further removes remaining polymers and chemicals.

Because re-refined oil goes through the same oil refining and distillation process as the crude oil that later becomes virgin, it can be as high of quality if not higher than virgin. Re-refining waste oil is environmentally friendly and requires significantly less energy to produce than virgin. Re-refined motor oils can be refined again and again, keeping them in circulation versus becoming waste products.
