Q
how is used engine oil recycled
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Recycling used engine oil involves several steps:
1. Collection: Used engine oil is collected from various sources such as garages, car establishments, and service centers.
2. Dehydration: Collected oil is dehydrated to remove any water content. This can be done by heating the oil.
3. Pre-treatment: The used oil is then pre-treated to remove impurities such as solids and lighter fuels. This is done through a filtration process.
4. Distillation: In this process, the oil is heated at high temperature to separate the lighter and heavier components of the oil. The lighter components are removed first, followed by the lube cut, which is used to make new lubricating oils.
5. Hydro-treating: The lube cut is treated with hydrogen under high pressure to remove any contaminants such as sulfur, nitrogen, and traces of heavy metals. This is known as hydrotreating.
6. Quality Control: The recycled oil is tested to ensure it meets all quality standards for making new lubricants.
7. Re-Refining: Finally, the clean, recycled oil can be used as base oil, which can be further refined and blended to produce new lubricating oils or can be used in other industrial processes.
This recycling process helps in conserving natural resources and also reduces the impact on the environment.
