Used Oil

Brief Introduction:
Used oil refers to oils that have lost their original properties after being used in car engines, industrial machinery, or hydraulic systems. Over time, used oil accumulates impurities and particles, making it less effective for its original purpose. It is considered hazardous waste and must be properly recycled or disposed of to prevent environmental harm.

Product Category:
Used oil falls under recycled fossil fuels and hazardous industrial waste.

Applications:

1. Recycling and Re-refining:
   • Used oil can be refined again to produce lubricants or industrial fuels.
2. Industrial Fuel:
   • Some industries use used oil as a fuel for their boilers and furnaces.
3. Energy Production:
   • It can be used in energy generation processes.

Scientific Properties:

• Chemical Composition: Varies depending on the base oil, but often includes hydrocarbons, heavy metals, and byproducts from engine combustion and wear.
• Density: Approximately 0.87 to 0.91 g/cm³.
• Flash Point: Typically between 150°C and 200°C.
• Contaminants: Includes heavy metals, suspended particles, and various chemical pollutants.

Consumption Barriers:

• Environmental Pollution: Used oil is highly contaminated and improper disposal can cause serious environmental damage.
• Low Efficiency: When used as fuel, it has lower efficiency compared to primary fuels.

Hazards:

• Environmental Contamination: If improperly disposed of, used oil can contaminate water and soil.
• Fire Risk: Used oil is still flammable and can cause fires if exposed to heat sources.
• Toxicity: It may contain harmful chemicals that are dangerous to human health and the environment.

Standards:
Used oil must be managed according to environmental safety and recycling standards, such as the EPA (Environmental Protection Agency) guidelines and the EU Waste Oil Directive.

Storage Conditions:
Used oil should be stored in durable tanks away from heat sources and sparks. These tanks should be properly sealed to prevent leaks and contamination.
