The regeneration of waste engine oil is to remove impurities in engine oil by means of precipitation, distillation, acid washing, alkali washing and filtration. It is a toxic substance and a solid hazardous waste that is explicitly prohibited by the state. It is strictly forbidden to buy and sell waste engine oil at will, and it should be handled by qualified waste engine oil treatment enterprises.
The waste engine oil itself is not damaged much, but the additives in it have expired in cumulative use and contain impurities in the engine. After purification and adding new additives, it can be returned to the market as regenerated engine oil with the same performance.
Function of waste engine oil
Waste engine oil can also lubricate parts with low requirements for lubricating oil. For example, mechanical metal hinges such as the chain of our bicycles, the cab locks of excavators, loaders and other equipment can be coated with waste engine oil to achieve lubrication, friction reduction and rust prevention.
In the construction site, waste engine oil can be used in building formwork to prevent the formwork from sticking to cement, and it can also play a role in rust prevention and corrosion protection.
Although diesel oil extracted from waste engine oil may damage the fuel system of vehicles, it is not a big problem to use it in cooking stoves used by catering enterprises or some machinery factories. Moreover, the price of fuel extracted from waste engine oil is much cheaper than the gas on the market, and some catering enterprises and machinery factories are also willing to use this fuel.
